However, this value + is defined in the PDF and PostScript specs, and that algorithm is + better than the one FreeType currently uses: + + FreeType: Use the middle of the bounding box as the X coordinate + of the vertical origin. + + Adobe PDF spec: Use the middle of the horizontal advance vector as + the X coordinate of the vertical origin. + + FreeType's algorithm goes wrong if you have a really small glyph + (like the full-width, circle-like dot at the end of the sentence, as + used in CJK scripts) with large bearings. With the FreeType + algorithm this dot gets centered on the baseline; with the PDF + algorithm it gets the correct location (in the top right). Note + that this is a serious issue, it's like printing the dot at the end + of a Roman sentence at the center of the textline instead of on the + baseline like it should. So i believe the PDF spec's algorithm + should be used in FreeType as well. + + The `vertBearingY' value for such small glyphs is also very strange + if no `vmtx' information is present, since the height of the bbox is + not representable for the height of the glyph visually (the + whitespace up to the baseline is part of the glyph).

However, there are fonts like `pala.ttf' + which additionally contain this instruction in the hinting code of + some glyphs (but not all). As a result it can happen that a + composite glyph needs multiple drop-out modes for its subglyphs + since the rendering state gets reset for each subglyph. + + FreeType collects the hinted outlines from all subglyphs, then it + sends the data to the rasterizer. It also sends the drop-out mode + -- after hinting has been applied -- and here is the error: It sends + the drop-out mode of the last subglyph only; drop-out modes of all + other subglyphs are lost. + + This patch fixes the problem; it adds a second, alternative + mechanism to pass the drop-out mode: For each contour, the + rasterizer now checks the first `tags' array element.

The old code was too rigorous and suppressed more + pixel than it should. + + . The intersection of the two profiles with the scanline is less + than a half pixel. Code related to this was already present in + the sources but has been commented out. + + .

This glyph is a composite; + the first component, `E', has an advance width of 1366 font units, + while the advance width of the composite itself (which looks like + uppercase `E' with dieresis) is 1367 font units. I think this is + actually a bug in the font itself, because there is no reason that + this glyph has not the same width as uppercase `E' without the + dieresis. Anyway, it helped identify this problem. + + Using the TrueType hinter, the correct value (1367) of `afii10023' + was returned, but the autohinter mysteriously returned 1366. + + Digging in the code showed that the autohinter recursively calls + FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load + flag. However, the `linearHoriAdvance' field is still returned as a + scaled value. To avoid scaling twice, the old code in autofit reset + `linearHoriAdvance', using the `horiAdvance' field. This seemed to + work since FT_LOAD_NO_SCALE was in use, but it failed actually, + because `horiAdvance' is defined as the distance of the first + subglyph's phantom points, which in turn are initialized using the + advance width of the first subglyph. And as the given example + shows, these widths can differ. + + * src/autofit/afloader.c (af_loader_load_g): Temporarily set + FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled + values for the linear advance widths. + +2012-03-10 Werner Lemberg + + [truetype] Fix SSW instruction. + + * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units.

Indeed, the meanings of + `miter' and `bevel' were incorrectly reversed (consistently) in + both the code and comments. + + o The way bevel joins were constructed (whether specified + explicitly, or created as a result of exceeding the miter limit) + did not match what is required for stroked text in PostScript or + PDF. + + The main fixes + -------------- + + o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. + + o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been + introduced to support PostScript and PDF miter joins. + + o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an + alias for FT_STROKER_LINEJOIN_MITER. + + Additionally, a variety of stroking errors have been fixed. These + would cause various artifacts (including points `at infinity'), + especially when stroking poor quality fonts. + + See + + http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html + + for example documents. The FreeType stroker now produces results + very similar to that produced by GhostScript and Distiller for these + fonts. + + Other problems + -------------- + + The following problems have been resolved: + + o Inside corners could be generated incorrectly. Intersecting the + inside corner could cause a missing triangular area and other + effects. + + The intersection point can only be used if the join is between + two lines and both lines are long enough. The `optimization' + condition in `ft_stroker_inside' has been corrected; this + requires the line length to be passed into various functions and + stored in `FT_StrokerRec'. + + o Incorrect cubic curves could be generated. The angle + calculations in `FT_Stroker_CubicTo' have been corrected to + handle the case of the curve crossing the +/-PI direction. + + o If the border radius was greater than the radius of curvature of + a curve, then the negative sector would end up outside (not + inside) the border. This situation is now recognized and the + negative sector is circumnavigated in the opposite direction. + (If round line joins are being used, this code is disabled + because the line join will always cover the negative sector.) + + o When a curve is split, the arcs may not join smoothly (especially + if the curve turns sharply back on itself). Changes in + direction between adjacent arcs were not handled. A round + corner is now added if the deviation from one arc to the next is + greater than a suitable threshold. + + o The current direction wasn't retained if a the outline contained + a zero length lineto or a curve that was determined to be + `basically a point'. This could cause a spurious join to be + added. + + o Cubics with close control points could be mishandled. All eight + cases are now distinguished correctly. + + Other improvements + ------------------ + + o Borders for cubic curves could be too `flat'. + FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent + this. + + o The handling and use of movable points has been simplified a + little. + + o Various values are now computed only if the results are actually + needed. + + o The directions of the outer and inner borders have been swapped, + as recommended by Graham Asher. + + * src/base/ftstroke.c: Revised. + * include/freetype/ftstroke.h: Updated. + +2011-06-30 İsmail Dönmez + + * builds/toplevel.mk: We use git, not CVS, thus skip `.gitignore'. + +2011-06-29 Werner Lemberg + + [bdf] Fix Savannah bug #33663. + + * src/bdf/bdflib.c (_bdf_parse_glyphs): Handle negative values for + ENCODING correctly. + + * docs/CHANGES: Document it. + +2011-06-24 Werner Lemberg + + * Version 2.4.5 released. + ========================= + + + Tag sources with `VER-2-4-5'. + + * docs/CHANGES: Updated. + + * docs/VERSION.DLL: Update documentation and bump version number to + 2.4.5 + + * README, Jamfile (RefDoc), + builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, + builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, + builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, + builds/win32/visualc/freetype.dsp, + builds/win32/visualc/freetype.vcproj, + builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, + builds/win32/visualce/freetype.vcproj, + builds/win32/visualce/index.html, + builds/wince/vc2005-ce/freetype.vcproj, + builds/wince/vc2005-ce/index.html, + builds/wince/vc2008-ce/freetype.vcproj, + builds/wince/vc2008-ce/index.html: s/2.4.4/2.4.5/, s/244/245/. + + * include/freetype/freetype.h (FREETYPE_PATCH): Set to 5. + + * builds/unix/configure.raw (version_info): Set to 13:0:7. + +2011-06-20 Werner Lemberg + + * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Fix change + from 2011-05-04. + +2011-06-19 suzuki toshiya + + [gxvalid] make the `prop' validation tracing verbose. + + * src/gxvalid/gxvprop.c: Add tracing messages for errors. + +2011-06-19 suzuki toshiya + + [autogen.sh] Reflect environment variable LIBTOOLIZE. + +2011-06-18 Werner Lemberg + + Update license documentation. + + * docs/GPL.TXT: Renamed to... + * docs/GPLv2.TXT: This. + + * docs/LICENSE.TXT: Updated. + +2011-06-14 suzuki toshiya + + Fix g++4.6 compiler warnings in module drivers. + + The background is same with previous commit. + + * src/truetype/ttgxvar.c (ft_var_readpackedpoints): + Init `points'.

This directory contains project files for Visual C++, named -freetype.dsp, and Visual Studio, called freetype.sln. It -compiles the following libraries from the FreeType 2.3.12 sources:

- -
    -
    -    freetype2312.lib     - release build; single threaded
    -    freetype2312_D.lib   - debug build;   single threaded
    -    freetype2312MT.lib   - release build; multi-threaded
    -    freetype2312MT_D.lib - debug build;   multi-threaded
    -
- -

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

- FreeType 2 Project Files for Visual C++ and VS.NET 2005 - (Pocket PC) -

- -

This directory contains project files for Visual C++, named -freetype.dsp, and Visual Studio, called freetype.sln for -the following targets: - -

    -
  • PPC/SP 2003 (Pocket PC 2003)
  • -
  • PPC/SP WM5 (Windows Mobile 5)
  • -
  • PPC/SP WM6 (Windows Mobile 6)
  • -
- -It compiles the following libraries from the FreeType 2.3.12 sources:

- -
    -
    -    freetype2312.lib     - release build; single threaded
    -    freetype2312_D.lib   - debug build;   single threaded
    -    freetype2312MT.lib   - release build; multi-threaded
    -    freetype2312MT_D.lib - debug build;   multi-threaded
    -
- -

Be sure to extract the files with the Windows (CR+LF) line endings. ZIP -archives are already stored this way, so no further action is required. If -you use some .tar.*z archives, be sure to configure your extracting -tool to convert the line endings. For example, with WinZip, you should activate the TAR -file smart CR/LF Conversion option. Alternatively, you may consider -using the unix2dos or u2d utilities that are floating -around, which specifically deal with this particular problem. - -

Build directories are placed in the top-level objs -directory.

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    + FreeType 2 Project Files for VS.NET 2010 or newer +

    + +

    This directory contains a project file for Visual C++ (VS.NET 2010 +or newer), named freetype.vcxproj, and Visual Studio, called +freetype.sln. It compiles the following libraries from the +FreeType 2.5.4 sources:

    + +
      +
      +freetype254.lib     - release build
      +freetype254d.lib    - debug build
      +freetype254ST.lib   - release build; single threaded
      +freetype254STd.lib  - debug build;   single threaded
      +freetype254MT.lib   - release build; multi-threaded
      +freetype254MTd.lib  - debug build;   multi-threaded
      +
    + +

    Both Win32 and x64 builds are supported.

    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs\vc2010 +directory.

    + +

    Customization of the FreeType library is done by editing the +ftoptions.h header file in the top-level devel path. +Alternatively, you may copy the file to another directory and change the +include directory in freetype.users.props.

    + +

    To configure library dependencies like zlib and libpng, +edit the freetype.users.props file in this directory. It also +simplifies automated (command-line) builds using msbuild.

    + FreeType 2 Project Files for Visual C++ and VS.NET 2005 +

    + +

    This directory contains project files for Visual C++, named +freetype.dsp, and Visual Studio, called freetype.sln. It +compiles the following libraries from the FreeType 2.5.4 sources:

    + +
      +
      +    freetype254.lib     - release build; single threaded
      +    freetype254_D.lib   - debug build;   single threaded
      +    freetype254MT.lib   - release build; multi-threaded
      +    freetype254MT_D.lib - debug build;   multi-threaded
      +
    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs +directory.

    + FreeType 2 Project Files for Visual C++ and VS.NET 2005 + (Pocket PC) +

    + +

    This directory contains project files for Visual C++, named +freetype.dsp, and Visual Studio, called freetype.sln for +the following targets: + +

      +
    • PPC/SP 2003 (Pocket PC 2003)
    • +
    • PPC/SP WM5 (Windows Mobile 5)
    • +
    • PPC/SP WM6 (Windows Mobile 6)
    • +
    + +It compiles the following libraries from the FreeType 2.5.4 sources:

    + +
      +
      +    freetype254.lib     - release build; single threaded
      +    freetype254_D.lib   - debug build;   single threaded
      +    freetype254MT.lib   - release build; multi-threaded
      +    freetype254MT_D.lib - debug build;   multi-threaded
      +
    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs +directory.

This is for orthogonality with all other + enumeration (and enumeration-like) values in FreeType. + + - `cmake' now supports builds of FreeType as an OS X framework and + for iOS. + + - Improved project files for vc2010, introducing a property file. + + - The documentation generator for the API reference has been + updated to produce better HTML code (with proper CSS). At the + same time, the documentation got a better structure. + + - The FT_LOAD_BITMAP_CROP flag is obsolete; it is not used by any + driver. + + - The TrueType DELTAP[123] bytecode instructions now work in + subpixel hinting mode as described in the ClearType whitepaper + (i.e., for touched points in the non-subpixel direction). + + - Many small improvements to the internal arithmetic routines. + + +====================================================================== + +CHANGES BETWEEN 2.5.2 and 2.5.3 + + I. IMPORTANT BUG FIXES + + - A vulnerability (CVE-2014-2240) was identified and fixed in the + new CFF driver (cf. http://savannah.nongnu.org/bugs/?41697). + All users should upgrade. + + - More bug fixes related to correct positioning of composite + glyphs. + + - Many fixes to better protect against malformed input. + + + II. IMPORTANT CHANGES + + - FreeType can now use the HarfBuzz library to greatly improve the + auto-hinting of fonts that use OpenType features: Many glyphs + that are part of such features but don't have cmap entries are + now handled properly, for example small caps or superscripts. + Define the configuration macro FT_CONFIG_OPTION_USE_HARFBUZZ to + activate HarfBuzz support. + + You need HarfBuzz version 0.9.19 or newer. + + Note that HarfBuzz depends on FreeType; this currently causes a + chicken-and-egg problem that can be solved as follows in case + HarfBuzz is not yet installed on your system. + + 1. Compile and install FreeType without the configuration + macro FT_CONFIG_OPTION_USE_HARFBUZZ. + + 2. Compile and install HarfBuzz. + + 3. Define macro FT_CONFIG_OPTION_USE_HARFBUZZ, then compile + and install FreeType again. + + With FreeType's `configure' script the procedure boils down to + configure, build, and install Freetype, then configure, compile, + and install HarfBuzz, then configure, compile, and install + FreeType again (after executing `make distclean'). + + - All libraries FreeType depends on are now checked using the + `pkg-config' configuration files first, followed by alternative + methods. + + - The new value `auto' for the various `--with-XXX' library + options (for example `--with-harfbuzz=auto') makes the + `configure' script automatically link to the libraries it finds. + This is now the default. + + - In case FreeType's `configure' script can't find a library, you + can pass environment variables to circumvent pkg-config, and + those variables have been harmonized as a consequence of the + changes mentioned above: + + LIBZ -> removed; use LIBZ_CFLAGS and LIBZ_LIBS + LIBBZ2 -> removed; use BZIP2_CFLAGS and BZIP2_LIBS + LIBPNG_LDFLAGS -> LIBPNG_LIBS + + `./configure --help' shows all available environment variables. + + - The `freetype-config' script now understands option `--static' + to emit static linking information. + + +====================================================================== + +CHANGES BETWEEN 2.5.1 and 2.5.2 + + I. IMPORTANT BUG FIXES + + - Improving the display of some broken TrueType fonts introduced a + bug that made FreeType crash on some popular (but not fully + conformant) fonts like `ahronbd.ttf'. + + - Another round of improvements to correct positioning and hinting + of composite glyphs in TrueType fonts. + + + II. MISCELLANEOUS + + - Version 2.5.1 introduced a bug in handling embedded bitmap + strikes of TrueType fonts, causing garbage display under some + circumstances. + + - The `ftgrid' demo program couldn't be compiled in + non-development builds. + + +====================================================================== + +CHANGES BETWEEN 2.5 and 2.5.1 + + I. IMPORTANT BUG FIXES + + - For some WinFNT files, the last glyph wasn't displayed but + incorrectly marked as invalid. + + - The vertical size of glyphs was incorrectly set after a call to + `FT_GlyphSlot_Embolden', resulting in clipped glyphs. + + - Many fields of the `PCLT' table in SFNT based fonts (if accessed + with `FT_Get_Sfnt_Table') were computed incorrectly. + + - In TrueType fonts, hinting of composite glyphs could sometimes + deliver incorrect positions of components or even distorted + shapes. + + + II. IMPORTANT CHANGES + + - WOFF font format support has been added. + + - The auto-hinter now supports Hebrew. Greek and Cyrillic support + has been improved. + + - Support for the forthcoming `OS/2' SFNT table version 5, as can + be found e.g. in the `Sitka' font family for Windows 8.1. + + - The header file layout has been changed. After installation, + all files are now located in `/include/freetype2'. + + Applications that use (a) `freetype-config' or FreeType's + `pkg-config' file to get the include directory for the compiler, + and (b) the documented way for header inclusion like + + #include + #include FT_FREETYPE_H + ... + + don't need any change to the source code. + + + III. MISCELLANEOUS + + - The stem darkening feature of the new CFF engine can now be + fine-tuned with the new `darkening-parameters' property. + + - `ftgrid' has been updated to toggle various engines with the `H' + key, similar to `ftview' and `ftdiff'. + + - The functionality of `ttdebug' has been greatly enhanced. + + . It now displays twilight, storage, and control value data; key + `T' shows the twilight point table, key `S' the storage data, + and key `C' the control value table. + + . Some keys have been reassigned from lowercase to their + uppercase equivalents; for example `q' to quit the program is + now `Q'. + + . Key `f' finishes the current function. + + . Key `R' restarts the debugger. + + . Keys `b' and `p' set a breakpoint. + + . Key `B' provides a function call backtrace. + + - Better support of ARMv7 and x86_64 processors. + + - Apple's `sbix' color bitmap format is now supported. + + - Improved auto-hinter rendering for many TrueType fonts, + especially in the range 20-40ppem. + + - A new face flag `FT_FACE_FLAG_COLOR' has been added (to be + accessed with the macro `FT_HAS_COLOR'). + + - `FT_Gzip_Uncompress' (modeled after zlib's `uncompress' + function) has been added; this is a by-product of the newly + added WOFF support. + + - Support for a build with `cmake' has been contributed by John + Cary . + + - Support for x64 builds with Visual C++ has been contributed by + Kenneth Miller + + - Manual pages for most demo programs have been added. + + - The GETINFO bytecode instruction for TrueType fonts was buggy if + used to retrieve subpixel hinting information. It was necessary + to set selector bit 6 to get results for selector bits 7-10, + which is wrong. + + - Improved computation of emulated vertical metrics for TrueType + fonts. + + - Fixed horizontal start-up position of vertical phantom points in + TrueType bytecode. + + +====================================================================== + +CHANGES BETWEEN 2.4.12 and 2.5 + + I. IMPORTANT BUG FIXES + + - The cache manager function `FTC_Manager_Reset' didn't flush the + cache. + + + II. IMPORTANT CHANGES + + - Behdad Esfahbod (on behalf of Google) contributed support for + color embedded bitmaps (eg. color emoji). + + A new load flag, FT_LOAD_COLOR, makes FreeType load color + embedded-bitmaps, following this draft specification + + https://color-emoji.googlecode.com/git/specification/v1.html + + which defines two new SFNT tables, `CBDT' and `CBLC' (named and + modeled after `EBDT' and `EBLC', respectively). The color + bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to + represent BGRA pre-multiplied sRGB images. If PNG support is + available, PNG color images as defined in the same proposed + specification are supported also. + + Note that color bitmaps are converted to grayscale if client + didn't ask for color. + + - As announced in the previous release, the old FreeType CFF + engine is now disabled by default. It can be conditionally + compiled by defining the configuration macro + CFF_CONFIG_OPTION_OLD_ENGINE. + + - As announced in the previous release, all code related to macro + FT_CONFIG_OPTION_OLD_INTERNALS has been removed, thus becoming + obsolete. + + + III. MISCELLANEOUS + + - The property API (`FT_Property_Get' and `FT_Property_Set') is + now declared as stable. + + The exception, however, are the experimental auto-hinter + properties `glyph-to-script-map' and `fallback-script' which are + subject to change in a forthcoming release. + + - `ftview' has been updated to support color embedded bitmaps; it + can be toggled on and off with key `c'. The small cache toggle + is now key `K'. + + - It is now possible to control the version of the TrueType + hinting engine using the new `interpreter-version' property of + the `truetype' module: Versions 35 and 38 (the default) are + supported, which roughly corresponds to disable and enable + subpixel hinting support, respectively. + + In both `ftview' and `ftdiff', switching between the two + versions can be done with key `H'. In the `ftbench' demo + program, command line option `-H' has been extended to activate + the non-default interpreter version. + + - The `ttdebug' program has been further improved. In particular, + it accepts a new command line option `-H' to select the hinting + engine. + + - `ftdump's verbose option has been renamed to `-V'. For all demo + programs, `-v' now shows version information. + + - Another round of TrueType subpixel hinting fixes. + + - The `apinames' tool can now create an import file for NetWare. + + - 64bit compilation of the new CFF engine was buggy. + + - Some fixes to improve robustness in memory-tight situations. + + +====================================================================== + +CHANGES BETWEEN 2.4.11 and 2.4.12 + + - We have another CFF parsing and hinting engine!

IMPORTANT BUG FIXES + + - Some vulnerabilities in the BDF implementation have been fixed. + Users of this font format should upgrade. + + + II. IMPORTANT CHANGES + + - Subpixel hinting support has been contributed by Infinality, + based on Greg Hitchcock's whitepaper at + + http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx + + Originally, it was a separate patch available from + + http://www.infinality.net/blog/ + + and which has been integrated. + + Note that ClearType support is not completely implemented!

MISCELLANEOUS + + - Minor rendering improvements to the auto-hinter. + + - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°. + + - Experimental support to handle `property modules', for example + to control the behaviour of the auto-hinter. The API consists + of two new functions, `FT_Property_Set' and `FT_Property_Get'. + + The code is still subject to change and should not be used for + production. + + - The `ftdiff' demo program now supports UTF-8 encoded input files + for option `-f'. + + - Using keys `r' and `R', you can now adjust the stroker radius in + the `ftview' demo program. + + - Other, minor fixes and improvements. + + +====================================================================== + +CHANGES BETWEEN 2.4.9 and 2.4.10 + + I.

IMPORTANT BUG FIXES + + - For TrueType based fonts, the ascender and descender values were + incorrect sometimes (off by a pixel if the ppem value was not a + multiple of 5). Depending on the use you might now experience + a different layout; the change should result in better, more + consistent line spacing. + + - Fix CVE-2011-0226 which causes a vulnerability while handling + Type 1 fonts. + + - BDF fonts containing glyphs with negative values for ENCODING + were incorrectly rejected. This bug has been introduced in + FreeType version 2.2.0. + + - David Bevan contributed a major revision of the FreeType stroker + code: + + .

MISCELLANEOUS + + - Detect tricky fonts (e.g. MingLiU) by the lengths and checksums + of Type42-persistent subtables (`cvt ', `fpgm', and `prep') when + a TrueType font without family name is given. The previous fix, + introduced in 2.4.3, was too rigorous, causing many subsetted + fonts (mainly from PDF files) displayed badly because FreeType + forced rendering with the TrueType bytecode engine instead of + the autohinter. + + - Better support for 64bit platforms. + + - More fixes to improve handling of broken fonts. + + +====================================================================== + +CHANGES BETWEEN 2.4.2 and 2.4.3 + + I. IMPORTANT BUG FIXES + + - Fix rendering of certain cubic, S-shaped arcs. This regression + has been introduced in version 2.4.0. + + + II.

The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License.

If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code.

For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6.

If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

Ensure that you are using GNU Make - ------------------------------------- - - The FreeType build system _exclusively_ works with GNU Make (as an - exception you can use make++ which emulates GNU Make sufficiently; - see http://makepp.sourceforge.net). You will not be able to compile - the library with the instructions below using any other alternative - (including BSD Make). - - Trying to compile the library with a different Make tool prints a - message like: - - Sorry, GNU make is required to build FreeType2. - - and the build process is aborted. If this happens, install GNU Make - on your system, and use the GNUMAKE environment variable to name it. - - - 4. Build and install the library - -------------------------------- - - The following should work on all Unix systems where the `make' - command invokes GNU Make: - - ./configure --prefix= - make - make install (as root) - - where `' must be replaced by the prefix returned by the - `freetype-config' command. - - When using a different command to invoke GNU Make, use the GNUMAKE - variable. For example, if `gmake' is the command to use on your - system, do something like: - - GNUMAKE=gmake ./configure --prefix= - gmake - gmake install (as root) - - - 5. Take care of XFree86 version 4 - --------------------------------- - - Certain Linux distributions install _several_ versions of FreeType - on your system. For example, on a fresh Mandrake 8.1 system, you - can find the following files: - - /usr/lib/libfreetype.so which links to - /usr/lib/libfreetype.6.1.0.so - - and - - /usr/X11R6/lib/libfreetype.so which links to - /usr/X11R6/lib/libfreetype.6.0.so - - Note that these files correspond to two distinct versions of the - library!

    FT_Library

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  typedef struct FT_LibraryRec_  *FT_Library;
    -
    -

    -
    -

    A handle to a FreeType library instance. Each ‘library’ is completely independent from the others; it is the ‘root’ of a set of objects like fonts, faces, sizes, etc.

    -

    It also embeds a memory manager (see FT_Memory), as well as a scan-line converter object (see FT_Raster).

    -

    For multi-threading applications each thread should have its own FT_Library object.

    -

    -
    note
    -

    Library objects are normally created by FT_Init_FreeType, and destroyed with FT_Done_FreeType.

    FT_Face

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  typedef struct FT_FaceRec_*  FT_Face;
    -
    -

    -
    -

    A handle to a given typographic face object. A face object models a given typeface, in a given style.

    -

    -
    note
    -

    Each face object also owns a single FT_GlyphSlot object, as well as one or more FT_Size objects.

    -

    Use FT_New_Face or FT_Open_Face to create a new face object from a given filepathname or a custom input stream.

    -

    Use FT_Done_Face to destroy it (along with its slot and sizes).

    -
    -
    also
    -

    See FT_FaceRec for the publicly accessible fields of a given face object.

    FT_Size

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  typedef struct FT_SizeRec_*  FT_Size;
    -
    -

    -
    -

    A handle to an object used to model a face scaled to a given character size.

    -

    -
    note
    -

    Each FT_Face has an active FT_Size object that is used by functions like FT_Load_Glyph to determine the scaling transformation which is used to load and hint glyphs and metrics.

    -

    You can use FT_Set_Char_Size, FT_Set_Pixel_Sizes, FT_Request_Size or even FT_Select_Size to change the content (i.e., the scaling values) of the active FT_Size.

    -

    You can use FT_New_Size to create additional size objects for a given FT_Face, but they won't be used by other functions until you activate it through FT_Activate_Size. Only one size can be activated at any given time per face.

    -
    -

    -

    See FT_SizeRec for the publicly accessible fields of a given size object.

    FT_GlyphSlot

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  typedef struct FT_GlyphSlotRec_*  FT_GlyphSlot;
    -
    -

    -
    -

    A handle to a given ‘glyph slot’. A slot is a container where it is possible to load any of the glyphs contained in its parent face.

    -

    In other words, each time you call FT_Load_Glyph or FT_Load_Char, the slot's content is erased by the new glyph data, i.e., the glyph's metrics, its image (bitmap or outline), and other control information.

    FT_CharMap

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  typedef struct FT_CharMapRec_*  FT_CharMap;
    -
    -

    -
    -

    A handle to a given character map. A charmap is used to translate character codes in a given encoding into glyph indexes for its parent's face. Some font formats may provide several charmaps per font.

    -

    Each face object owns zero or more charmaps, but only one of them can be ‘active’ and used by FT_Get_Char_Index or FT_Load_Char.

    -

    The list of available charmaps in a face is available through the ‘face->num_charmaps’ and ‘face->charmaps’ fields of FT_FaceRec.

    -

    The currently active charmap is available as ‘face->charmap’. You should call FT_Set_Charmap to change it.

    -

    -
    note
    -

    When a new face is created (either through FT_New_Face or FT_Open_Face), the library looks for a Unicode charmap within the list and automatically activates it.

    -

    -
    -

    An enumeration used to specify character sets supported by charmaps. Used in the FT_Select_Charmap API function.

    -

    -
    note
    -

    Despite the name, this enumeration lists specific character repertories (i.e., charsets), and not text encoding methods (e.g., UTF-8, UTF-16, etc.).

    -

    Other encodings might be defined in the future.

    -
    values
    -

    - - - - - - - - - - - - - - - - - - - - - - - - - - -
    FT_ENCODING_NONE -

    The encoding value 0 is reserved.

    -
    FT_ENCODING_UNICODE -

    Corresponds to the Unicode character set. This value covers all versions of the Unicode repertoire, including ASCII and Latin-1. Most fonts include a Unicode charmap, but not all of them.

    -

    For example, if you want to access Unicode value U+1F028 (and the font contains it), use value 0x1F028 as the input value for FT_Get_Char_Index.

    -
    FT_ENCODING_MS_SYMBOL -

    Corresponds to the Microsoft Symbol encoding, used to encode mathematical symbols in the 32..255 character code range. For more information, see ‘http://www.ceviz.net/symbol.htm’.

    -
    FT_ENCODING_SJIS -

    Corresponds to Japanese SJIS encoding. More info at at ‘http://langsupport.japanreference.com/encoding.shtml’. See note on multi-byte encodings below.

    -
    FT_ENCODING_GB2312 -

    Corresponds to an encoding system for Simplified Chinese as used used in mainland China.

    -
    FT_ENCODING_BIG5 -

    Corresponds to an encoding system for Traditional Chinese as used in Taiwan and Hong Kong.

    -
    FT_ENCODING_WANSUNG -

    Corresponds to the Korean encoding system known as Wansung. For more information see ‘http://www.microsoft.com/typography/unicode/949.txt’.

    -
    FT_ENCODING_JOHAB -

    The Korean standard character set (KS C 5601-1992), which corresponds to MS Windows code page 1361. This character set includes all possible Hangeul character combinations.

    -
    FT_ENCODING_ADOBE_LATIN_1
    -

    Corresponds to a Latin-1 encoding as defined in a Type 1 PostScript font. It is limited to 256 character codes.

    -
    FT_ENCODING_ADOBE_STANDARD
    -

    Corresponds to the Adobe Standard encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes.

    -
    FT_ENCODING_ADOBE_EXPERT
    -

    Corresponds to the Adobe Expert encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes.

    -
    FT_ENCODING_ADOBE_CUSTOM
    -

    Corresponds to a custom encoding, as found in Type 1, CFF, and OpenType/CFF fonts. It is limited to 256 character codes.

    -
    FT_ENCODING_APPLE_ROMAN
    -

    Corresponds to the 8-bit Apple roman encoding. Many TrueType and OpenType fonts contain a charmap for this encoding, since older versions of Mac OS are able to use it.

    -
    FT_ENCODING_OLD_LATIN_2
    -

    This value is deprecated and was never used nor reported by FreeType. Don't use or test for it.

    -
    FT_ENCODING_MS_SJIS -

    Same as FT_ENCODING_SJIS. Deprecated.

    -
    FT_ENCODING_MS_GB2312 -

    Same as FT_ENCODING_GB2312. Deprecated.

    -
    FT_ENCODING_MS_BIG5 -

    Same as FT_ENCODING_BIG5. Deprecated.

    -
    FT_ENCODING_MS_WANSUNG -

    Same as FT_ENCODING_WANSUNG. Deprecated.

    -
    FT_ENCODING_MS_JOHAB -

    Same as FT_ENCODING_JOHAB. Deprecated.

    -
    -
    -
    note
    -

    By default, FreeType automatically synthesizes a Unicode charmap for PostScript fonts, using their glyph names dictionaries. However, it also reports the encodings defined explicitly in the font file, for the cases when they are needed, with the Adobe values as well.

    -

    FT_ENCODING_NONE is set by the BDF and PCF drivers if the charmap is neither Unicode nor ISO-8859-1 (otherwise it is set to FT_ENCODING_UNICODE). Use FT_Get_BDF_Charset_ID to find out which encoding is really present. If, for example, the ‘cs_registry’ field is ‘KOI8’ and the ‘cs_encoding’ field is ‘R’, the font is encoded in KOI8-R.

    -

    FT_ENCODING_NONE is always set (with a single exception) by the winfonts driver. Use FT_Get_WinFNT_Header and examine the ‘charset’ field of the FT_WinFNT_HeaderRec structure to find out which encoding is really present. For example, FT_WinFNT_ID_CP1251 (204) means Windows code page 1251 (for Russian).

    -

    FT_ENCODING_NONE is set if ‘platform_id’ is TT_PLATFORM_MACINTOSH and ‘encoding_id’ is not TT_MAC_ID_ROMAN (otherwise it is set to FT_ENCODING_APPLE_ROMAN).

    -

    If ‘platform_id’ is TT_PLATFORM_MACINTOSH, use the function FT_Get_CMap_Language_ID to query the Mac language ID which may be needed to be able to distinguish Apple encoding variants. See

    -

    http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/README.TXT

    -

    to get an idea how to do that. Basically, if the language ID is 0, don't use it, otherwise subtract 1 from the language ID. Then examine ‘encoding_id’. If, for example, ‘encoding_id’ is TT_MAC_ID_ROMAN and the language ID (minus 1) is ‘TT_MAC_LANGID_GREEK’, it is the Greek encoding, not Roman. TT_MAC_ID_ARABIC with ‘TT_MAC_LANGID_FARSI’ means the Farsi variant the Arabic encoding.

    -
    -

    -
    -

    A structure used to model the metrics of a single glyph. The values are expressed in 26.6 fractional pixel format; if the flag FT_LOAD_NO_SCALE has been used while loading the glyph, values are expressed in font units instead.

    -

    -
    -  } FT_Bitmap_Size;
    -
    -

    -
    -

    This structure models the metrics of a bitmap strike (i.e., a set of glyphs for a given point size and resolution) in a bitmap font. It is used for the ‘available_sizes’ field of FT_Face.

    -

    -
    fields
    -

    - - - - - - -
    height -

    The vertical distance, in pixels, between two consecutive baselines. It is always positive.

    -
    width -

    The average width, in pixels, of all glyphs in the strike.

    -
    size -

    The nominal size of the strike in 26.6 fractional points. This field is not very useful.

    -
    x_ppem -

    The horizontal ppem (nominal width) in 26.6 fractional pixels.

    -
    y_ppem -

    The vertical ppem (nominal height) in 26.6 fractional pixels.

    -
    -
    -
    note
    -

    Windows FNT: The nominal size given in a FNT font is not reliable. Thus when the driver finds it incorrect, it sets ‘size’ to some calculated values and sets ‘x_ppem’ and ‘y_ppem’ to the pixel width and height given in the font, respectively.

    -

    TrueType embedded bitmaps: ‘size’, ‘width’, and ‘height’ values are not contained in the bitmap strike itself. They are computed from the global font parameters.

    This macro converts four-letter tags into an unsigned long. It is used to define ‘encoding’ identifiers (see FT_Encoding).

    -

    -
    note
    -

    Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:

    -
    -  #define FT_ENC_TAG( value, a, b, c, d )  value                   
    -
    -

    to get a simple enumeration without assigning special numbers.

    FreeType root face class structure. A face object models a typeface in a font file.

    -

    -
    fields
    -

    - - - - - - - - - - - - - - - - - - - - - - - - - -
    num_faces -

    The number of faces in the font file. Some font formats can have multiple faces in a font file.

    -
    face_index -

    The index of the face in the font file. It is set to 0 if there is only one face in the font file.

    -
    face_flags -

    A set of bit flags that give important information about the face; see FT_FACE_FLAG_XXX for the details.

    -
    style_flags -

    A set of bit flags indicating the style of the face; see FT_STYLE_FLAG_XXX for the details.

    -
    num_glyphs -

    The number of glyphs in the face. If the face is scalable and has sbits (see ‘num_fixed_sizes’), it is set to the number of outline glyphs.

    -

    For CID-keyed fonts, this value gives the highest CID used in the font.

    -
    family_name -

    The face's family name. This is an ASCII string, usually in English, which describes the typeface's family (like ‘Times New Roman’, ‘Bodoni’, ‘Garamond’, etc). This is a least common denominator used to list fonts. Some formats (TrueType & OpenType) provide localized and Unicode versions of this string. Applications should use the format specific interface to access them. Can be NULL (e.g., in fonts embedded in a PDF file).

    -
    style_name -

    The face's style name. This is an ASCII string, usually in English, which describes the typeface's style (like ‘Italic’, ‘Bold’, ‘Condensed’, etc). Not all font formats provide a style name, so this field is optional, and can be set to NULL. As for ‘family_name’, some formats provide localized and Unicode versions of this string. Applications should use the format specific interface to access them.

    -
    num_fixed_sizes -

    The number of bitmap strikes in the face. Even if the face is scalable, there might still be bitmap strikes, which are called ‘sbits’ in that case.

    -
    available_sizes -

    An array of FT_Bitmap_Size for all bitmap strikes in the face. It is set to NULL if there is no bitmap strike.

    -
    num_charmaps -

    The number of charmaps in the face.

    -
    charmaps -

    An array of the charmaps of the face.

    -
    generic -

    A field reserved for client uses. See the FT_Generic type description.

    -
    bbox -

    The font bounding box. Coordinates are expressed in font units (see ‘units_per_EM’). The box is large enough to contain any glyph from the font. Thus, ‘bbox.yMax’ can be seen as the ‘maximal ascender’, and ‘bbox.yMin’ as the ‘minimal descender’. Only relevant for scalable formats.

    -

    Note that the bounding box might be off by (at least) one pixel for hinted fonts. See FT_Size_Metrics for further discussion.

    -
    units_per_EM -

    The number of font units per EM square for this face. This is typically 2048 for TrueType fonts, and 1000 for Type 1 fonts. Only relevant for scalable formats.

    -
    ascender -

    The typographic ascender of the face, expressed in font units. For font formats not having this information, it is set to ‘bbox.yMax’. Only relevant for scalable formats.

    -
    descender -

    The typographic descender of the face, expressed in font units. For font formats not having this information, it is set to ‘bbox.yMin’. Note that this field is usually negative. Only relevant for scalable formats.

    -
    height -

    The height is the vertical distance between two consecutive baselines, expressed in font units. It is always positive. Only relevant for scalable formats.

    -
    max_advance_width -

    The maximal advance width, in font units, for all glyphs in this face. This can be used to make word wrapping computations faster. Only relevant for scalable formats.

    -
    max_advance_height -

    The maximal advance height, in font units, for all glyphs in this face. This is only relevant for vertical layouts, and is set to ‘height’ for fonts that do not provide vertical metrics. Only relevant for scalable formats.

    -
    underline_position -

    The position, in font units, of the underline line for this face. It is the center of the underlining stem. Only relevant for scalable formats.

    -
    underline_thickness -

    The thickness, in font units, of the underline for this face. Only relevant for scalable formats.

    -
    glyph -

    The face's associated glyph slot(s).

    -
    size -

    The current active size for this face.

    -
    charmap -

    The current active charmap for this face.

    -
    values
    -

    - - - - - - - - - - - - - - - - - - - - - - -
    FT_FACE_FLAG_SCALABLE -

    Indicates that the face contains outline glyphs. This doesn't prevent bitmap strikes, i.e., a face can have both this and and FT_FACE_FLAG_FIXED_SIZES set.

    -
    FT_FACE_FLAG_FIXED_SIZES
    -

    Indicates that the face contains bitmap strikes. See also the ‘num_fixed_sizes’ and ‘available_sizes’ fields of FT_FaceRec.

    -
    FT_FACE_FLAG_FIXED_WIDTH
    -

    Indicates that the face contains fixed-width characters (like Courier, Lucido, MonoType, etc.).

    -
    FT_FACE_FLAG_SFNT -

    Indicates that the face uses the ‘sfnt’ storage scheme. For now, this means TrueType and OpenType.

    -
    FT_FACE_FLAG_HORIZONTAL
    -

    Indicates that the face contains horizontal glyph metrics. This should be set for all common formats.

    -
    FT_FACE_FLAG_VERTICAL -

    Indicates that the face contains vertical glyph metrics. This is only available in some formats, not all of them.

    -
    FT_FACE_FLAG_KERNING -

    Indicates that the face contains kerning information. If set, the kerning distance can be retrieved through the function FT_Get_Kerning. Otherwise the function always return the vector (0,0). Note that FreeType doesn't handle kerning data from the ‘GPOS’ table (as present in some OpenType fonts).

    -
    FT_FACE_FLAG_FAST_GLYPHS
    -

    THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT.

    -
    FT_FACE_FLAG_MULTIPLE_MASTERS
    -

    Indicates that the font contains multiple masters and is capable of interpolating between them. See the multiple-masters specific API for details.

    -
    FT_FACE_FLAG_GLYPH_NAMES
    -

    Indicates that the font contains glyph names that can be retrieved through FT_Get_Glyph_Name. Note that some TrueType fonts contain broken glyph name tables. Use the function FT_Has_PS_Glyph_Names when needed.

    -
    FT_FACE_FLAG_EXTERNAL_STREAM
    -

    Used internally by FreeType to indicate that a face's stream was provided by the client application and should not be destroyed when FT_Done_Face is called. Don't read or test this flag.

    -
    FT_FACE_FLAG_HINTER -

    Set if the font driver has a hinting machine of its own. For example, with TrueType fonts, it makes sense to use data from the SFNT ‘gasp’ table only if the native TrueType hinting engine (with the bytecode interpreter) is available and active.

    -
    FT_FACE_FLAG_CID_KEYED -

    Set if the font is CID-keyed. In that case, the font is not accessed by glyph indices but by CID values. For subsetted CID-keyed fonts this has the consequence that not all index values are a valid argument to FT_Load_Glyph. Only the CID values for which corresponding glyphs in the subsetted font exist make FT_Load_Glyph return successfully; in all other cases you get an ‘FT_Err_Invalid_Argument’ error.

    -

    Note that CID-keyed fonts which are in an SFNT wrapper don't have this flag set since the glyphs are accessed in the normal way (using contiguous indices); the ‘CID-ness’ isn't visible to the application.

    -
    FT_FACE_FLAG_TRICKY -

    Set if the font is ‘tricky’, this is, it always needs the font format's native hinting engine to get a reasonable result. A typical example is the Chinese font ‘mingli.ttf’ which uses TrueType bytecode instructions to move and scale all of its subglyphs.

    -

    It is not possible to autohint such fonts using FT_LOAD_FORCE_AUTOHINT; it will also ignore FT_LOAD_NO_HINTING. You have to set both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT to really disable hinting; however, you probably never want this except for demonstration purposes.

    -

    Currently, there are six TrueType fonts in the list of tricky fonts; they are hard-coded in file ‘ttobjs.c’.

    The size metrics structure gives the metrics of a size object.

    -

    -
    fields
    -

    - - - - - - - - - -
    x_ppem -

    The width of the scaled EM square in pixels, hence the term ‘ppem’ (pixels per EM). It is also referred to as ‘nominal width’.

    -
    y_ppem -

    The height of the scaled EM square in pixels, hence the term ‘ppem’ (pixels per EM). It is also referred to as ‘nominal height’.

    -
    x_scale -

    A 16.16 fractional scaling value used to convert horizontal metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats.

    -
    y_scale -

    A 16.16 fractional scaling value used to convert vertical metrics from font units to 26.6 fractional pixels. Only relevant for scalable font formats.

    -
    ascender -

    The ascender in 26.6 fractional pixels. See FT_FaceRec for the details.

    -
    descender -

    The descender in 26.6 fractional pixels. See FT_FaceRec for the details.

    -
    height -

    The height in 26.6 fractional pixels. See FT_FaceRec for the details.

    -
    max_advance -

    The maximal advance width in 26.6 fractional pixels. See FT_FaceRec for the details.

    -
    -
    -
    note
    -

    The scaling values, if relevant, are determined first during a size changing operation. The remaining fields are then set by the driver. For scalable formats, they are usually set to scaled values of the corresponding fields in FT_FaceRec.

    -

    Note that due to glyph hinting, these values might not be exact for certain fonts. Thus they must be treated as unreliable with an error margin of at least one pixel!

    -

    Indeed, the only way to get the exact metrics is to render all glyphs. As this would be a definite performance hit, it is up to client applications to perform such computations.

    -

    The FT_Size_Metrics structure is valid for bitmap fonts also.

    -
    -

    FreeType root glyph slot class structure. A glyph slot is a container where individual glyphs can be loaded, be they in outline or bitmap format.

    -

    -
    fields
    -

    - - - - - - - - - - - - - - - - - - - - - -
    library -

    A handle to the FreeType library instance this slot belongs to.

    -
    face -

    A handle to the parent face object.

    -
    next -

    In some cases (like some font tools), several glyph slots per face object can be a good thing. As this is rare, the glyph slots are listed through a direct, single-linked list using its ‘next’ field.

    -
    generic -

    A typeless pointer which is unused by the FreeType library or any of its drivers. It can be used by client applications to link their own data to each glyph slot object.

    -
    metrics -

    The metrics of the last loaded glyph in the slot. The returned values depend on the last load flags (see the FT_Load_Glyph API function) and can be expressed either in 26.6 fractional pixels or font units.

    -

    Note that even when the glyph image is transformed, the metrics are not.

    -
    linearHoriAdvance -

    The advance width of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for outline glyphs.

    -
    linearVertAdvance -

    The advance height of the unhinted glyph. Its value is expressed in 16.16 fractional pixels, unless FT_LOAD_LINEAR_DESIGN is set when loading the glyph. This field can be important to perform correct WYSIWYG layout. Only relevant for outline glyphs.

    -
    advance -

    This shorthand is, depending on FT_LOAD_IGNORE_TRANSFORM, the transformed advance width for the glyph (in 26.6 fractional pixel format). As specified with FT_LOAD_VERTICAL_LAYOUT, it uses either the ‘horiAdvance’ or the ‘vertAdvance’ value of ‘metrics’ field.

    -
    format -

    This field indicates the format of the image contained in the glyph slot. Typically FT_GLYPH_FORMAT_BITMAP, FT_GLYPH_FORMAT_OUTLINE, or FT_GLYPH_FORMAT_COMPOSITE, but others are possible.

    -
    bitmap -

    This field is used as a bitmap descriptor when the slot format is FT_GLYPH_FORMAT_BITMAP. Note that the address and content of the bitmap buffer can change between calls of FT_Load_Glyph and a few other functions.

    -
    bitmap_left -

    This is the bitmap's left bearing expressed in integer pixels. Of course, this is only valid if the format is FT_GLYPH_FORMAT_BITMAP.

    -
    bitmap_top -

    This is the bitmap's top bearing expressed in integer pixels. Remember that this is the distance from the baseline to the top-most glyph scanline, upwards y coordinates being positive.

    -
    outline -

    The outline descriptor for the current glyph image if its format is FT_GLYPH_FORMAT_OUTLINE. Once a glyph is loaded, ‘outline’ can be transformed, distorted, embolded, etc. However, it must not be freed.

    -
    num_subglyphs -

    The number of subglyphs in a composite glyph. This field is only valid for the composite glyph format that should normally only be loaded with the FT_LOAD_NO_RECURSE flag. For now this is internal to FreeType.

    -
    subglyphs -

    An array of subglyph descriptors for composite glyphs. There are ‘num_subglyphs’ elements in there. Currently internal to FreeType.

    -
    control_data -

    Certain font drivers can also return the control data for a given glyph image (e.g. TrueType bytecode, Type 1 charstrings, etc.). This field is a pointer to such data.

    -
    control_len -

    This is the length in bytes of the control data.

    -
    other -

    Really wicked formats can use this pointer to present their own glyph image to client applications. Note that the application needs to know about the image format.

    -
    lsb_delta -

    The difference between hinted and unhinted left side bearing while autohinting is active. Zero otherwise.

    -
    rsb_delta -

    The difference between hinted and unhinted right side bearing while autohinting is active. Zero otherwise.

    -
    -
    -
    note
    -

    If FT_Load_Glyph is called with default flags (see FT_LOAD_DEFAULT) the glyph image is loaded in the glyph slot in its native format (e.g., an outline glyph for TrueType and Type 1 formats).

    -

    This image can later be converted into a bitmap by calling FT_Render_Glyph. This function finds the current renderer for the native image's format, then invokes it.

    -

    The renderer is in charge of transforming the native image through the slot's face transformation fields, then converting it into a bitmap that is returned in ‘slot->bitmap’.

    -

    Note that ‘slot->bitmap_left’ and ‘slot->bitmap_top’ are also used to specify the position of the bitmap relative to the current pen position (e.g., coordinates (0,0) on the baseline). Of course, ‘slot->format’ is also changed to FT_GLYPH_FORMAT_BITMAP.

    Here a small pseudo code fragment which shows how to use ‘lsb_delta’ and ‘rsb_delta’:

    -
    -  FT_Pos  origin_x       = 0;                                      
    -  FT_Pos  prev_rsb_delta = 0;                                      
    -

    -  for all glyphs do                                                
    -    <compute kern between current and previous glyph and add it to

    -    <load glyph with `FT_Load_Glyph'>

    -    if ( prev_rsb_delta - face->glyph->lsb_delta >= 32 )           
    -      origin_x -= 64;                                              
    -    else if ( prev_rsb_delta - face->glyph->lsb_delta < -32 )

    -
    fields
    -

    - - - - - - - - - -
    flags -

    A set of bit flags indicating how to use the structure.

    -
    memory_base -

    The first byte of the file in memory.

    -
    memory_size -

    The size in bytes of the file in memory.

    -
    pathname -

    A pointer to an 8-bit file pathname.

    -
    stream -

    A handle to a source stream object.

    -
    driver -

    This field is exclusively used by FT_Open_Face; it simply specifies the font driver to use to open the face. If set to 0, FreeType tries to load the face with each one of the drivers in its list.

    -
    num_params -

    The number of extra parameters.

    -
    params -

    Extra parameters passed to the font driver when opening a new face.

    -
    -
    -
    note
    -

    The stream type is determined by the contents of ‘flags’ which are tested in the following order by FT_Open_Face:

    -

    If the ‘FT_OPEN_MEMORY’ bit is set, assume that this is a memory file of ‘memory_size’ bytes, located at ‘memory_address’. The data are are not copied, and the client is responsible for releasing and destroying them after the corresponding call to FT_Done_Face.

    -

    Otherwise, if the ‘FT_OPEN_STREAM’ bit is set, assume that a custom input stream ‘stream’ is used.

    -

    Otherwise, if the ‘FT_OPEN_PATHNAME’ bit is set, assume that this is a normal file and use ‘pathname’ to open it.

    -

    If the ‘FT_OPEN_DRIVER’ bit is set, FT_Open_Face only tries to open the file with the driver whose handler is in ‘driver’.

    -

    If the ‘FT_OPEN_PARAMS’ bit is set, the parameters given by ‘num_params’ and ‘params’ is used. They are ignored otherwise.

    -

    Ideally, both the ‘pathname’ and ‘params’ fields should be tagged as ‘const’; this is missing for API backwards compatibility. In other words, applications should treat them as read-only.

    -

    Unlike FreeType 1.x, this function automatically creates a glyph slot for the face object which can be accessed directly through ‘face->glyph’.

    -

    FT_Open_Face can be used to quickly check whether the font format of a given font resource is supported by FreeType. If the ‘face_index’ field is negative, the function's return value is 0 if the font format is recognized, or non-zero otherwise; the function returns a more or less empty face handle in ‘*aface’ (if ‘aface’ isn't NULL). The only useful field in this special case is ‘face->num_faces’ which gives the number of faces within the font file. After examination, the returned FT_Face structure should be deallocated with a call to FT_Done_Face.

    -

    Each new face object created with this function also owns a default FT_Size object, accessible as ‘face->size’.

    note
    -

    The meaning of the ‘attach’ (i.e., what really happens when the new file is read) is not fixed by FreeType itself. It really depends on the font format (and thus the font driver).

    -

    Client applications are expected to know what they are doing when invoking this function. Most drivers simply do not implement file attachments.

    values
    -

    - - - - - - - - - - - -
    FT_SIZE_REQUEST_TYPE_NOMINAL
    -

    The nominal size. The ‘units_per_EM’ field of FT_FaceRec is used to determine both scaling values.

    -
    FT_SIZE_REQUEST_TYPE_REAL_DIM
    -

    The real dimension. The sum of the the ‘Ascender’ and (minus of) the ‘Descender’ fields of FT_FaceRec are used to determine both scaling values.

    -
    FT_SIZE_REQUEST_TYPE_BBOX
    -

    The font bounding box. The width and height of the ‘bbox’ field of FT_FaceRec are used to determine the horizontal and vertical scaling value, respectively.

    -
    FT_SIZE_REQUEST_TYPE_CELL
    -

    The ‘max_advance_width’ field of FT_FaceRec is used to determine the horizontal scaling value; the vertical scaling value is determined the same way as FT_SIZE_REQUEST_TYPE_REAL_DIM does. Finally, both scaling values are set to the smaller one. This type is useful if you want to specify the font size for, say, a window of a given dimension and 80x24 cells.

    -
    FT_SIZE_REQUEST_TYPE_SCALES
    -

    Specify the scaling values directly.

    -
    -
    -
    note
    -

    The above descriptions only apply to scalable formats. For bitmap formats, the behaviour is up to the driver.

    -
    -

    A list of bit-field constants used with FT_Load_Glyph to indicate what kind of operations to perform during glyph loading.

    -

    -
    values
    -

    - - - - - - - - - - - - - - - - - - - -
    FT_LOAD_DEFAULT -

    Corresponding to 0, this value is used as the default glyph load operation. In this case, the following happens:

    -

    1. FreeType looks for a bitmap for the glyph corresponding to the face's current size. If one is found, the function returns. The bitmap data can be accessed from the glyph slot (see note below).

    -

    2. If no embedded bitmap is searched or found, FreeType looks for a scalable outline. If one is found, it is loaded from the font file, scaled to device pixels, then ‘hinted’ to the pixel grid in order to optimize it. The outline data can be accessed from the glyph slot (see note below).

    -

    Note that by default, the glyph loader doesn't render outlines into bitmaps. The following flags are used to modify this default behaviour to more specific and useful cases.

    -
    FT_LOAD_NO_SCALE -

    Don't scale the outline glyph loaded, but keep it in font units.

    -

    This flag implies FT_LOAD_NO_HINTING and FT_LOAD_NO_BITMAP, and unsets FT_LOAD_RENDER.

    -
    FT_LOAD_NO_HINTING -

    Disable hinting. This generally generates ‘blurrier’ bitmap glyph when the glyph is rendered in any of the anti-aliased modes. See also the note below.

    -

    This flag is implied by FT_LOAD_NO_SCALE.

    -
    FT_LOAD_RENDER -

    Call FT_Render_Glyph after the glyph is loaded. By default, the glyph is rendered in FT_RENDER_MODE_NORMAL mode. This can be overridden by FT_LOAD_TARGET_XXX or FT_LOAD_MONOCHROME.

    -

    This flag is unset by FT_LOAD_NO_SCALE.

    -
    FT_LOAD_NO_BITMAP -

    Ignore bitmap strikes when loading. Bitmap-only fonts ignore this flag.

    -

    FT_LOAD_NO_SCALE always sets this flag.

    -
    FT_LOAD_VERTICAL_LAYOUT
    -

    Load the glyph for vertical text layout. Don't use it as it is problematic currently.

    -
    FT_LOAD_FORCE_AUTOHINT -

    Indicates that the auto-hinter is preferred over the font's native hinter. See also the note below.

    -
    FT_LOAD_CROP_BITMAP -

    Indicates that the font driver should crop the loaded bitmap glyph (i.e., remove all space around its black bits). Not all drivers implement this.

    -
    FT_LOAD_PEDANTIC -

    Indicates that the font driver should perform pedantic verifications during glyph loading. This is mostly used to detect broken glyphs in fonts. By default, FreeType tries to handle broken fonts also.

    -
    FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH
    -

    Indicates that the font driver should ignore the global advance width defined in the font. By default, that value is used as the advance width for all glyphs when the face has FT_FACE_FLAG_FIXED_WIDTH set.

    -

    This flag exists for historical reasons (to support buggy CJK fonts).

    -
    FT_LOAD_NO_RECURSE -

    This flag is only used internally. It merely indicates that the font driver should not load composite glyphs recursively. Instead, it should set the ‘num_subglyph’ and ‘subglyphs’ values of the glyph slot accordingly, and set ‘glyph->format’ to FT_GLYPH_FORMAT_COMPOSITE.

    -

    The description of sub-glyphs is not available to client applications for now.

    -

    This flag implies FT_LOAD_NO_SCALE and FT_LOAD_IGNORE_TRANSFORM.

    -
    FT_LOAD_IGNORE_TRANSFORM
    -

    Indicates that the transform matrix set by FT_Set_Transform should be ignored.

    -
    FT_LOAD_MONOCHROME -

    This flag is used with FT_LOAD_RENDER to indicate that you want to render an outline glyph to a 1-bit monochrome bitmap glyph, with 8 pixels packed into each byte of the bitmap data.

    -

    Note that this has no effect on the hinting algorithm used. You should rather use FT_LOAD_TARGET_MONO so that the monochrome-optimized hinting algorithm is used.

    -
    FT_LOAD_LINEAR_DESIGN -

    Indicates that the ‘linearHoriAdvance’ and ‘linearVertAdvance’ fields of FT_GlyphSlotRec should be kept in font units. See FT_GlyphSlotRec for details.

    -
    FT_LOAD_NO_AUTOHINT -

    Disable auto-hinter. See also the note below.

    By default, hinting is enabled and the font's native hinter (see FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can disable hinting by setting FT_LOAD_NO_HINTING or change the precedence by setting FT_LOAD_FORCE_AUTOHINT. You can also set FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be used at all.

    -

    See the description of FT_FACE_FLAG_TRICKY for a special exception (affecting only a handful of Asian fonts).

    -

    Besides deciding which hinter to use, you can also decide which hinting algorithm to use. See FT_LOAD_TARGET_XXX for details.

    FT_LOAD_TARGET_XXX

    -#define FT_LOAD_TARGET_LCD_V   FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V  )
    -
    -

    -
    -

    A list of values that are used to select a specific hinting algorithm to use by the hinter. You should OR one of these values to your ‘load_flags’ when calling FT_Load_Glyph.

    -

    Note that font's native hinters may ignore the hinting algorithm you have specified (e.g., the TrueType bytecode interpreter). You can set FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.

    -

    Also note that FT_LOAD_TARGET_LIGHT is an exception, in that it always implies FT_LOAD_FORCE_AUTOHINT.

    -

    -
    values
    -

    - - - - - - -
    FT_LOAD_TARGET_NORMAL -

    This corresponds to the default hinting algorithm, optimized for standard gray-level rendering. For monochrome output, use FT_LOAD_TARGET_MONO instead.

    -
    FT_LOAD_TARGET_LIGHT -

    A lighter hinting algorithm for non-monochrome modes. Many generated glyphs are more fuzzy but better resemble its original shape. A bit like rendering on Mac OS X.

    -

    As a special exception, this target implies FT_LOAD_FORCE_AUTOHINT.

    -
    FT_LOAD_TARGET_MONO -

    Strong hinting algorithm that should only be used for monochrome output. The result is probably unpleasant if the glyph is rendered in non-monochrome modes.

    -
    FT_LOAD_TARGET_LCD -

    A variant of FT_LOAD_TARGET_NORMAL optimized for horizontally decimated LCD displays.

    -
    FT_LOAD_TARGET_LCD_V -

    A variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays.

    -
    -
    -
    note
    -

    You should use only one of the FT_LOAD_TARGET_XXX values in your ‘load_flags’. They can't be ORed.

    -

    If FT_LOAD_RENDER is also set, the glyph is rendered in the corresponding mode (i.e., the mode which matches the used algorithm best) unless FT_LOAD_MONOCHROME is set.

    -

    You can use a hinting algorithm that doesn't correspond to the same rendering mode. As an example, it is possible to use the ‘light’ hinting algorithm and have the results rendered in horizontal LCD pixel mode, with code like

    -
    -  FT_Load_Glyph( face, glyph_index,
    -                 load_flags | FT_LOAD_TARGET_LIGHT );
    -
    -  FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );

    -                    FT_Vector*  delta );
    -
    -

    -
    -

    A function used to set the transformation that is applied to glyph images when they are loaded into a glyph slot through FT_Load_Glyph.

    -

    -
    inout
    -

    - - -
    face -

    A handle to the source face object.

    -
    -
    -
    input
    -

    - - - -
    matrix -

    A pointer to the transformation's 2x2 matrix. Use 0 for the identity matrix.

    -
    delta -

    A pointer to the translation vector. Use 0 for the null vector.

    -
    -
    -
    note
    -

    The transformation is only applied to scalable image formats after the glyph has been loaded. It means that hinting is unaltered by the transformation and is performed on the character size given in the last call to FT_Set_Char_Size or FT_Set_Pixel_Sizes.

    -

    Note that this also transforms the ‘face.glyph.advance’ field, but not the values in ‘face.glyph.metrics’.

    -  {
    -    FT_RENDER_MODE_NORMAL = 0,

    -    FT_RENDER_MODE_MAX
    -
    -  } FT_Render_Mode;
    -
    -

    -
    -

    An enumeration type that lists the render modes supported by FreeType 2. Each mode corresponds to a specific type of scanline conversion performed on the outline.

    -

    For bitmap fonts and embedded bitmaps the ‘bitmap->pixel_mode’ field in the FT_GlyphSlotRec structure gives the format of the returned bitmap.

    -

    All modes except FT_RENDER_MODE_MONO use 256 levels of opacity.

    -

    -
    values
    -

    - - - - - - -
    FT_RENDER_MODE_NORMAL -

    This is the default render mode; it corresponds to 8-bit anti-aliased bitmaps.

    -
    FT_RENDER_MODE_LIGHT -

    This is equivalent to FT_RENDER_MODE_NORMAL. It is only defined as a separate value because render modes are also used indirectly to define hinting algorithm selectors. See FT_LOAD_TARGET_XXX for details.

    -
    FT_RENDER_MODE_MONO -

    This mode corresponds to 1-bit bitmaps (with 2 levels of opacity).

    -
    FT_RENDER_MODE_LCD -

    This mode corresponds to horizontal RGB and BGR sub-pixel displays like LCD screens. It produces 8-bit bitmaps that are 3 times the width of the original glyph outline in pixels, and which use the FT_PIXEL_MODE_LCD mode.

    -
    FT_RENDER_MODE_LCD_V -

    This mode corresponds to vertical RGB and BGR sub-pixel displays (like PDA screens, rotated LCD displays, etc.). It produces 8-bit bitmaps that are 3 times the height of the original glyph outline in pixels and use the FT_PIXEL_MODE_LCD_V mode.

    -
    -
    -
    note
    -

    The LCD-optimized glyph bitmaps produced by FT_Render_Glyph can be filtered to reduce color-fringes by using FT_Library_SetLcdFilter (not active in the default builds). It is up to the caller to either call FT_Library_SetLcdFilter (if available) or do the filtering itself.

    -

    The selected render mode only affects vector glyphs of a font. Embedded bitmaps often have a different pixel mode like FT_PIXEL_MODE_MONO. You can use FT_Bitmap_Convert to transform them into 8-bit pixmaps.

    You should use this function with FT_Get_Next_Char to be able to parse all character codes available in a given charmap. The code should look like this:

    -
    -  FT_ULong  charcode;

    -  while ( gindex != 0 )                                            
    -  {                                                                
    -    ... do something with (charcode,gindex) pair ...               
    -

    -  }                                                                
    -
    -

    Note that ‘*agindex’ is set to 0 if the charmap is empty. The result itself can be 0 in two cases: if the charmap is empty or if the value 0 is the first valid character code.

    - - - - - - - - - - - - - -
    FT_FSTYPE_INSTALLABLE_EMBEDDING
    -

    Fonts with no fsType bit set may be embedded and permanently installed on the remote system by an application.

    -
    FT_FSTYPE_RESTRICTED_LICENSE_EMBEDDING
    -

    Fonts that have only this bit set must not be modified, embedded or exchanged in any manner without first obtaining permission of the font software copyright owner.

    -
    FT_FSTYPE_PREVIEW_AND_PRINT_EMBEDDING
    -

    If this bit is set, the font may be embedded and temporarily loaded on the remote system. Documents containing Preview & Print fonts must be opened ‘read-only’; no edits can be applied to the document.

    -
    FT_FSTYPE_EDITABLE_EMBEDDING
    -

    If this bit is set, the font may be embedded but must only be installed temporarily on other systems. In contrast to Preview & Print fonts, documents containing editable fonts may be opened for reading, editing is permitted, and changes may be saved.

    -
    FT_FSTYPE_NO_SUBSETTING
    -

    If this bit is set, the font may not be subsetted prior to embedding.

    -
    FT_FSTYPE_BITMAP_EMBEDDING_ONLY
    -

    If this bit is set, only bitmaps contained in the font may be embedded; no outline data may be embedded. If there are no bitmaps available in the font, then the font is unembeddable.

    -
    -
    -
    note
    -

    While the fsType flags can indicate that a font may be embedded, a license with the font vendor may be separately required to use the font in this way.

    -

    -
    fields
    -

    - - - - - -
    xMin -

    The horizontal minimum (left-most).

    -
    yMax -

    The vertical maximum (top-most).

    -
    -
    -
    note
    -

    The bounding box is specified with the coordinates of the lower left and the upper right corner. In PostScript, those values are often called (llx,lly) and (urx,ury), respectively.

    -

    If ‘yMin’ is negative, this value gives the glyph's descender. Otherwise, the glyph doesn't descend below the baseline. Similarly, if ‘ymax’ is positive, this value gives the glyph's ascender.

    -

    ‘xMin’ gives the horizontal distance from the glyph's origin to the left edge of the glyph's bounding box. If ‘xMin’ is negative, the glyph extends to the left of the origin.

    -
    -

    -
    -

    A structure used to describe a bitmap or pixmap to the raster. Note that we now manage pixmaps of various depths through the ‘pixel_mode’ field.

    -

    -
    fields
    -

    - - - - - - - - - -
    rows -

    The number of bitmap rows.

    -
    width -

    The number of pixels in bitmap row.

    -
    pitch -

    The pitch's absolute value is the number of bytes taken by one bitmap row, including padding. However, the pitch is positive when the bitmap has a ‘down’ flow, and negative when it has an ‘up’ flow. In all cases, the pitch is an offset to add to a bitmap pointer in order to go down one row.

    -

    For the B/W rasterizer, ‘pitch’ is always an even number.

    -
    buffer -

    A typeless pointer to the bitmap buffer. This value should be aligned on 32-bit boundaries in most cases.

    -
    num_grays -

    This field is only used with FT_PIXEL_MODE_GRAY; it gives the number of gray levels used in the bitmap.

    -
    pixel_mode -

    The pixel mode, i.e., how pixel bits are stored. See FT_Pixel_Mode for possible values.

    -
    palette_mode -

    This field is intended for paletted pixel modes; it indicates how the palette is stored. Not used currently.

    -
    palette -

    A typeless pointer to the bitmap palette; this field is intended for paletted pixel modes. Not used currently.

    -
    -
    -
    note
    -

    For now, the only pixel modes supported by FreeType are mono and grays. However, drivers might be added in the future to support more ‘colorful’ options.

    -#endif /* FT_IMAGE_TAG */
    -
    -

    -
    -

    This macro converts four-letter tags to an unsigned long type.

    -

    -
    note
    -

    Since many 16-bit compilers don't like 32-bit enumerations, you should redefine this macro in case of problems to something like this:

    -
    -  #define FT_IMAGE_TAG( value, _x1, _x2, _x3, _x4 )  value         
    -
    -

    to get a simple enumeration without assigning special numbers.

    -
    FT_GLYPH_FORMAT_COMPOSITE
    -

    The glyph image is a composite of several other images. This format is only used with FT_LOAD_NO_RECURSE, and is used to report compound glyphs (like accented characters).

    -
    FT_GLYPH_FORMAT_BITMAP -

    The glyph image is a bitmap, and can be described as an FT_Bitmap. You generally need to access the ‘bitmap’ field of the FT_GlyphSlotRec structure to read it.

    -
    FT_GLYPH_FORMAT_OUTLINE
    -

    The glyph image is a vectorial outline made of line segments and Bézier arcs; it can be described as an FT_Outline; you generally want to access the ‘outline’ field of the FT_GlyphSlotRec structure to read it.

    -
    FT_GLYPH_FORMAT_PLOTTER
    -

    The glyph image is a vectorial path with no inside and outside contours. Some Type 1 fonts, like those in the Hershey family, contain glyphs in this format. These are described as FT_Outline, but FreeType isn't currently capable of rendering them correctly.

    FT_Generic

    -Defined in FT_TYPES_H (freetype/fttypes.h). -

    -
    -
    -  typedef struct  FT_Generic_
    -  {
    -    void*                 data;

    -  } FT_Generic;
    -
    -

    -
    -

    Client applications often need to associate their own data to a variety of FreeType core objects. For example, a text layout API might want to associate a glyph cache to a given size object.

    -

    Most FreeType object contains a ‘generic’ field, of type FT_Generic, which usage is left to client applications and font servers.

    -

    It can be used to store a pointer to client-specific data, as well as the address of a ‘finalizer’ function, which will be called by FreeType when the object is destroyed (for example, the previous client example would put the address of the glyph cache destructor in the ‘finalizer’ field).

    -

    -
    fields
    -

    - - - -
    data -

    A typeless pointer to any client-specified data. This field is completely ignored by the FreeType library.

    -
    finalizer -

    A pointer to a ‘generic finalizer’ function, which will be called when the object is destroyed. If this field is set to NULL, no code will be called.

    FreeType error code. 0 means success.

    -
    -
    note
    -

    This function works with BDF and PCF fonts. It returns an error otherwise. It also returns an error if the property is not in the font.

    -

    A ‘property’ is a either key-value pair within the STARTPROPERTIES ... ENDPROPERTIES block of a BDF font or a key-value pair from the ‘info->props’ array within a ‘FontRec’ structure of a PCF font.

    -

    Integer properties are always stored as ‘signed’ within PCF fonts; consequently, BDF_PROPERTY_TYPE_CARDINAL is a possible return value for BDF fonts only.

    -

    In case of error, ‘aproperty->type’ is always set to BDF_PROPERTY_TYPE_NONE.

    -

    This section describes the FreeType 2 cache sub-system, which is used to limit the number of concurrently opened FT_Face and FT_Size objects, as well as caching information like character maps and glyph images while limiting their maximum memory usage.

    -

    Note that all types and functions begin with the ‘FTC_’ prefix.

    -

    The cache is highly portable and thus doesn't know anything about the fonts installed on your system, or how to access them. This implies the following scheme:

    -

    First, available or installed font faces are uniquely identified by FTC_FaceID values, provided to the cache by the client. Note that the cache only stores and compares these values, and doesn't try to interpret them in any way.

    -

    Second, the cache calls, only when needed, a client-provided function to convert a FTC_FaceID into a new FT_Face object. The latter is then completely managed by the cache, including its termination through FT_Done_Face.

    -

    Clients are free to map face IDs to anything else. The most simple usage is to associate them to a (pathname,face_index) pair that is used to call FT_New_Face. However, more complex schemes are also possible.

    -

    Note that for the cache to work correctly, the face ID values must be persistent, which means that the contents they point to should not change at runtime, or that their value should not become invalid.

    -

    If this is unavoidable (e.g., when a font is uninstalled at runtime), you should call FTC_Manager_RemoveFaceID as soon as possible, to let the cache get rid of any references to the old FTC_FaceID it may keep internally. Failure to do so will lead to incorrect behaviour or even crashes.

    -

    To use the cache, start with calling FTC_Manager_New to create a new FTC_Manager object, which models a single cache instance. You can then look up FT_Face and FT_Size objects with FTC_Manager_LookupFace and FTC_Manager_LookupSize, respectively.

    -

    If you want to use the charmap caching, call FTC_CMapCache_New, then later use FTC_CMapCache_Lookup to perform the equivalent of FT_Get_Char_Index, only much faster.

    -

    If you want to use the FT_Glyph caching, call FTC_ImageCache, then later use FTC_ImageCache_Lookup to retrieve the corresponding FT_Glyph objects from the cache.

    -

    If you need lots of small bitmaps, it is much more memory efficient to call FTC_SBitCache_New followed by FTC_SBitCache_Lookup. This returns FTC_SBitRec structures, which are used to store small bitmaps directly. (A small bitmap is one whose metrics and dimensions all fit into 8-bit integers).

    -

    We hope to also provide a kerning cache in the near future.

    -

    FTC_Manager

    -
    -Defined in FT_CACHE_H (freetype/ftcache.h). -

    -
    -  typedef struct FTC_ManagerRec_*  FTC_Manager;

    -

    This object corresponds to one instance of the cache-subsystem. It is used to cache one or more FT_Face objects, along with corresponding FT_Size objects.

    The manager intentionally limits the total number of opened FT_Face and FT_Size objects to control memory usage. See the ‘max_faces’ and ‘max_sizes’ parameters of FTC_Manager_New.

    -

    The manager is also used to cache ‘nodes’ of various types while limiting their total memory usage.

    -

    All limitations are enforced by keeping lists of managed objects in most-recently-used order, and flushing old nodes to make room for new ones.

    FTC_FaceID

    -
    -Defined in FT_CACHE_H (freetype/ftcache.h). -

    -
    -
    -  typedef FT_Pointer  FTC_FaceID;
    -
    -

    -
    -

    An opaque pointer type that is used to identity face objects. The contents of such objects is application-dependent.

    -

    These pointers are typically used to point to a user-defined structure containing a font file path, and face index.

    -

    -
    note
    -

    Never use NULL as a valid FTC_FaceID.

    -

    Face IDs are passed by the client to the cache manager, which calls, when needed, the FTC_Face_Requester to translate them into new FT_Face objects.

    -

    If the content of a given face ID changes at runtime, or if the value becomes invalid (e.g., when uninstalling a font), you should immediately call FTC_Manager_RemoveFaceID before any other cache function.

    -

    Failure to do so will result in incorrect behaviour or even memory leaks and crashes.

    -
    -
    note
    -

    The third parameter ‘req_data’ is the same as the one passed by the client when FTC_Manager_New is called.

    -

    The face requester should not perform funny things on the returned face object, like creating a new FT_Size for it, or setting a transformation through FT_Set_Transform!

    FTC_Node

    -Defined in FT_CACHE_H (freetype/ftcache.h). -

    -
    -
    -  typedef struct FTC_NodeRec_*  FTC_Node;
    -
    -

    -
    -

    An opaque handle to a cache node object. Each cache node is reference-counted. A node with a count of 0 might be flushed out of a full cache whenever a lookup request is performed.

    -

    If you lookup nodes, you have the ability to ‘acquire’ them, i.e., to increment their reference count. This will prevent the node from being flushed out of the cache until you explicitly ‘release’ it (see FTC_Node_Unref).

    -
    note
    -

    The returned FT_Face object is always owned by the manager. You should never try to discard it yourself.

    -

    The FT_Face object doesn't necessarily have a current size object (i.e., face->size can be 0). If you need a specific ‘font size’, use FTC_Manager_LookupSize instead.

    -

    Never change the face's transformation matrix (i.e., never call the FT_Set_Transform function) on a returned face! If you need to transform glyphs, do it yourself after glyph loading.

    -

    When you perform a lookup, out-of-memory errors are detected within the lookup and force incremental flushes of the cache until enough memory is released for the lookup to succeed.

    -

    If a lookup fails with ‘FT_Err_Out_Of_Memory’ the cache has already been completely flushed, and still no memory was available for the operation.

    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    The returned glyph is owned and managed by the glyph image cache. Never try to transform or discard it manually! You can however create a copy with FT_Glyph_Copy and modify the new one.

    -

    If ‘anode’ is not NULL, it receives the address of the cache node containing the glyph image, after increasing its reference count. This ensures that the node (as well as the FT_Glyph) will always be kept in the cache until you call FTC_Node_Unref to ‘release’ it.

    -

    If ‘anode’ is NULL, the cache node is left unchanged, which means that the FT_Glyph could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!

    FTC_ImageCache_LookupScaler

    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    The small bitmap descriptor and its bit buffer are owned by the cache and should never be freed by the application. They might as well disappear from memory on the next cache lookup, so don't treat them as persistent data.

    -

    The descriptor's ‘buffer’ field is set to 0 to indicate a missing glyph bitmap.

    -

    If ‘anode’ is not NULL, it receives the address of the cache node containing the bitmap, after increasing its reference count. This ensures that the node (as well as the image) will always be kept in the cache until you call FTC_Node_Unref to ‘release’ it.

    -

    If ‘anode’ is NULL, the cache node is left unchanged, which means that the bitmap could be flushed out of the cache on the next call to one of the caching sub-system APIs. Don't assume that it is persistent!

    FT_MulDiv

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  FT_EXPORT( FT_Long )
    -  FT_MulDiv( FT_Long  a,
    -             FT_Long  b,
    -             FT_Long  c );
    -
    -

    -
    -

    A very simple function used to perform the computation ‘(a*b)/c’ with maximal accuracy (it uses a 64-bit intermediate integer whenever necessary).

    -

    This function isn't necessarily as fast as some processor specific operations, but is at least completely portable.

    -

    -
    input
    -

    - - - - -
    a -

    The first multiplier.

    -
    b -

    The second multiplier.

    -
    c -

    The divisor.

    -
    -
    -
    return
    -

    The result of ‘(a*b)/c’. This function never traps when trying to divide by zero; it simply returns ‘MaxInt’ or ‘MinInt’ depending on the signs of ‘a’ and ‘b’.

    FT_MulFix

    -
    -Defined in FT_FREETYPE_H (freetype/freetype.h). -

    -
    -
    -  FT_EXPORT( FT_Long )
    -  FT_MulFix( FT_Long  a,
    -             FT_Long  b );
    -
    -

    -
    -

    A very simple function used to perform the computation ‘(a*b)/0x10000’ with maximal accuracy. Most of the time this is used to multiply a given value by a 16.16 fixed float factor.

    -

    -
    input
    -

    - - - -
    a -

    The first multiplier.

    -
    b -

    The second multiplier. Use a 16.16 factor here whenever possible (see note below).

    -
    -
    -
    return
    -

    The result of ‘(a*b)/0x10000’.

    -
    -
    note
    -

    This function has been optimized for the case where the absolute value of ‘a’ is less than 2048, and ‘b’ is a 16.16 scaling factor. As this happens mainly when scaling from notional units to fractional pixels in FreeType, it resulted in noticeable speed improvements between versions 2.x and 1.x.

    -

    As a conclusion, always try to place a 16.16 factor as the second argument of this function; this can make a great difference.

    -             FT_Long  b );
    -
    -

    -
    -

    A very simple function used to perform the computation ‘(a*0x10000)/b’ with maximal accuracy. Most of the time, this is used to divide a given value by a 16.16 fixed float factor.

    -

    -
    input
    -

    - - - -
    a -

    The first multiplier.

    -
    b -

    The second multiplier. Use a 16.16 factor here whenever possible (see note below).

    -
    -
    -
    return
    -

    The result of ‘(a*0x10000)/b’.

    -
    -
    note
    -

    The optimization for FT_DivFix() is simple: If (a << 16) fits in 32 bits, then the division is computed directly. Otherwise, we use a specialized version of FT_MulDiv.

    This section contains definitions used to manage glyph data through generic FT_Glyph objects. Each of them can contain a bitmap, a vector outline, or even images in other formats.

    FT_Glyph

    -
    -Defined in FT_GLYPH_H (freetype/ftglyph.h). -

    -
    -
    -  typedef struct FT_GlyphRec_*  FT_Glyph;
    -
    -

    -
    -

    Handle to an object used to model generic glyph images. It is a pointer to the FT_GlyphRec structure and can contain a glyph bitmap or pointer.

    -

    -
    note
    -

    Glyph objects are not owned by the library. You must thus release them manually (through FT_Done_Glyph) before calling FT_Done_FreeType.

    -    FT_Bitmap    bitmap;
    -
    -  } FT_BitmapGlyphRec;
    -

    -
    -

    A structure used for bitmap glyph images. This really is a ‘sub-class’ of FT_GlyphRec.

    -

    -
    fields
    -

    - - - - - -
    root -

    The root FT_Glyph fields.

    -
    left -

    The left-side bearing, i.e., the horizontal distance from the current pen position to the left border of the glyph bitmap.

    -
    top -

    The top-side bearing, i.e., the vertical distance from the current pen position to the top border of the glyph bitmap. This distance is positive for upwards y!

    -
    bitmap -

    A descriptor for the bitmap.

    -
    -
    -
    note
    -

    You can typecast an FT_Glyph to FT_BitmapGlyph if you have ‘glyph->format == FT_GLYPH_FORMAT_BITMAP’. This lets you access the bitmap's contents easily.

    -

    The corresponding pixel buffer is always owned by FT_BitmapGlyph and is thus created and destroyed with it.

    -
    -  } FT_OutlineGlyphRec;
    -
    -

    -
    -

    -

    -
    fields
    -

    - - - -
    root -

    The root FT_Glyph fields.

    -
    outline -

    A descriptor for the outline.

    -
    -
    -
    note
    -

    You can typecast an FT_Glyph to FT_OutlineGlyph if you have ‘glyph->format == FT_GLYPH_FORMAT_OUTLINE’. This lets you access the outline's content easily.

    -

    As the outline is extracted from a glyph slot, its coordinates are expressed normally in 26.6 pixels, unless the flag FT_LOAD_NO_SCALE was used in FT_Load_Glyph() or FT_Load_Char().

    -

    The outline's tables are always owned by the object and are destroyed with it.

    FT_Glyph_Get_CBox

    -
    -Defined in FT_GLYPH_H (freetype/ftglyph.h). -

    -
    -
    -  FT_EXPORT( void )
    -  FT_Glyph_Get_CBox( FT_Glyph  glyph,
    -                     FT_UInt   bbox_mode,
    -                     FT_BBox  *acbox );
    -
    -

    -
    -

    Return a glyph's ‘control box’. The control box encloses all the outline's points, including Bézier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline which contains Bézier outside arcs).

    -

    Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the ‘ftbbox’ component which is dedicated to this single task.

    -

    -
    input
    -

    - - - -
    glyph -

    A handle to the source glyph object.

    -
    mode -

    The mode which indicates how to interpret the returned bounding box values.

    -
    -
    -
    output
    -

    - - -
    acbox -

    The glyph coordinate bounding box. Coordinates are expressed in 1/64th of pixels if it is grid-fitted.

    -
    -
    -
    note
    -

    Coordinates are relative to the glyph origin, using the y upwards convention.

    -

    If the glyph has been loaded with FT_LOAD_NO_SCALE, ‘bbox_mode’ must be set to FT_GLYPH_BBOX_UNSCALED to get unscaled font units in 26.6 pixel format. The value FT_GLYPH_BBOX_SUBPIXELS is another name for this constant.

    -

    Note that the maximum coordinates are exclusive, which means that one can compute the width and height of the glyph image (be it in integer or 26.6 pixels) as:

    -
    -  width  = bbox.xMax - bbox.xMin;                                  
    -  height = bbox.yMax - bbox.yMin;                                  
    -
    -

    Note also that for 26.6 coordinates, if ‘bbox_mode’ is set to FT_GLYPH_BBOX_GRIDFIT, the coordinates will also be grid-fitted, which corresponds to:

    -
    -  bbox.xMin = FLOOR(bbox.xMin);                                    
    -  bbox.yMin = FLOOR(bbox.yMin);                                    
    -  bbox.xMax = CEILING(bbox.xMax);                                  
    -  bbox.yMax = CEILING(bbox.yMax);                                  
    -
    -

    To get the bbox in pixel coordinates, set ‘bbox_mode’ to FT_GLYPH_BBOX_TRUNCATE.

    -

    To get the bbox in grid-fitted pixel coordinates, set ‘bbox_mode’ to FT_GLYPH_BBOX_PIXELS.

    -

    Convert a given glyph object to a bitmap glyph object.

    -

    -
    inout
    -

    -

    - - - - -
    render_mode -

    An enumeration that describes how the data is rendered.

    -
    origin -

    A pointer to a vector used to translate the glyph image before rendering. Can be 0 (if no translation). The origin is expressed in 26.6 pixels.

    -
    destroy -

    A boolean that indicates that the original glyph image should be destroyed by this function. It is never destroyed in case of error.

    -
    -
    -
    return

    This component generates stroked outlines of a given vectorial glyph. It also allows you to retrieve the ‘outside’ and/or the ‘inside’ borders of the stroke.

    -

    This can be useful to generate ‘bordered’ glyph, i.e., glyphs displayed with a coloured (and anti-aliased) border around their shape.

    - - - - - - - -
    FT_STROKER_LINEJOIN_ROUND
    -

    Used to render rounded line joins. Circular arcs are used to join two lines smoothly.

    -
    FT_STROKER_LINEJOIN_BEVEL
    -

    Used to render beveled line joins; i.e., the two joining lines are extended until they intersect.

    -
    FT_STROKER_LINEJOIN_MITER
    -

    Same as beveled rendering, except that an additional line break is added if the angle between the two joining lines is too closed (this is useful to avoid unpleasant spikes in beveled rendering).

    values
    -

    - - - - -
    FT_STROKER_BORDER_LEFT -

    Select the left border, relative to the drawing direction.

    FT_STROKER_BORDER_RIGHT
    -

    Select the right border, relative to the drawing direction.

    -
    -
    -
    note
    -

    Applications are generally interested in the ‘inside’ and ‘outside’ borders. However, there is no direct mapping between these and the ‘left’ and ‘right’ ones, since this really depends on the glyph's drawing orientation, which varies between font formats.

    -

    You can however use FT_Outline_GetInsideBorder and FT_Outline_GetOutsideBorder to get these.

    -
    -

    -
    -

    A convenience function used to parse a whole outline with the stroker. The resulting outline(s) can be retrieved later by functions like FT_Stroker_GetCounts and FT_Stroker_Export.

    -

    -
    input
    -

    - - - - -
    stroker -

    The target stroker handle.

    -
    outline -

    The source outline.

    -
    opened -

    A boolean. If 1, the outline is treated as an open path instead of a closed one.

    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    If ‘opened’ is 0 (the default), the outline is treated as a closed path, and the stroker generates two distinct ‘border’ outlines.

    -

    If ‘opened’ is 1, the outline is processed as an open path, and the stroker generates a single ‘stroke’ outline.

    -

    This function calls FT_Stroker_Rewind automatically.

    When an outline, or a sub-path, is ‘closed’, the stroker generates two independent ‘border’ outlines, named ‘left’ and ‘right’.

    -

    When the outline, or a sub-path, is ‘opened’, the stroker merges the ‘border’ outlines with caps. The ‘left’ border receives all points, while the ‘right’ border becomes empty.

    -

    Use the function FT_Stroker_GetCounts instead if you want to retrieve the counts associated to both borders.

    -

    Many CJK characters have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Ideographic Variation Sequences (IVS), consisting of a Unicode base character and one of 240 variant selectors (U+E0100-U+E01EF), instead of further extending the already huge code range for CJK characters.

    -

    An IVS is registered and unique; for further details please refer to Unicode Technical Report #37, the Ideographic Variation Database. To date (October 2007), the character with the most variants is U+908A, having 8 such IVS.

    -

    Adobe and MS decided to support IVS with a new cmap subtable (format 14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variants supported by the font.

    -

    A variant may be either ‘default’ or ‘non-default’. A default variant is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variant is a different glyph.

    -
    note
    -

    If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the ‘missing glyph’.

    -

    This function is only meaningful if a) the font has a variation selector cmap sub table, and b) the current charmap has a Unicode encoding.

    -
    -
    note
    -

    This function only works with TrueTypeGX fonts, returning an error otherwise.

    -

    After use, the application should deallocate the buffers pointed to by each ‘tables’ element, by calling FT_TrueTypeGX_Free. A NULL value indicates that the table either doesn't exist in the font, the application hasn't asked for validation, or the validator doesn't have the ability to validate the sfnt table.

    This section contains the declaration of Gzip-specific functions.

    FT_Stream_OpenGzip

    -
    -Defined in FT_GZIP_H (freetype/ftgzip.h). -

    -
    -
    -  FT_EXPORT( FT_Error )
    -  FT_Stream_OpenGzip( FT_Stream  stream,
    -                      FT_Stream  source );
    -
    -

    -
    -

    Open a new stream to parse gzip-compressed font files. This is mainly used to support the compressed ‘*.pcf.gz’ fonts that come with XFree86.

    -

    -
    input
    -

    - - - -
    stream -

    The target embedding stream.

    -
    source -

    The source stream.

    -
    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    The source stream must be opened before calling this function.

    -

    Calling the internal function ‘FT_Stream_Close’ on the new stream will not call ‘FT_Stream_Close’ on the source stream. None of the stream objects will be released to the heap.

    -

    The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.

    -

    In certain builds of the library, gzip compression recognition is automatically handled when calling FT_New_Face or FT_Open_Face. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a gzipped stream from it and re-open the face with it.

    -

    This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with zlib support.

    The following macros are defined to the name of specific FreeType 2 header files. They can be used directly in #include statements as in:

    -
    -  #include FT_FREETYPE_H                                           
    -  #include FT_MULTIPLE_MASTERS_H                                   
    -  #include FT_GLYPH_H                                              
    -
    -

    There are several reasons why we are now using macros to name public header files. The first one is that such macros are not limited to the infamous 8.3 naming rule required by DOS (and ‘FT_MULTIPLE_MASTERS_H’ is a lot more meaningful than ‘ftmm.h’).

    -

    The second reason is that it allows for more flexibility in the way FreeType 2 is installed on a given system.

    This section contains various functions used to perform so-called ‘incremental’ glyph loading. This is a mode where all glyphs loaded from a given FT_Face are provided by the client application,

    -

    Apart from that, all other tables are loaded normally from the font file. This mode is useful when FreeType is used within another engine, e.g., a PostScript Imaging Processor.

    -

    To enable this mode, you must use FT_Open_Face, passing an FT_Parameter with the FT_PARAM_TAG_INCREMENTAL tag and an FT_Incremental_Interface value. See the comments for FT_Incremental_InterfaceRec for an example.

    -
    -
    -  typedef struct FT_IncrementalRec_*  FT_Incremental;
    -
    -

    -
    -

    An opaque type describing a user-provided object used to implement ‘incremental’ glyph loading within FreeType. This is used to support embedded fonts in certain environments (e.g., PostScript interpreters), where the glyph data isn't in the font file, or must be overridden by different values.

    -

    -
    note
    -

    It is up to client applications to create and implement FT_Incremental objects, as long as they provide implementations for the methods FT_Incremental_GetGlyphDataFunc, FT_Incremental_FreeGlyphDataFunc and FT_Incremental_GetGlyphMetricsFunc.

    -

    See the description of FT_Incremental_InterfaceRec to understand how to use incremental objects with FreeType.

    -
    -

    A function called by FreeType to access a given glyph's data bytes during FT_Load_Glyph or FT_Load_Char if incremental loading is enabled.

    -

    Note that the format of the glyph's data bytes depends on the font file format. For TrueType, it must correspond to the raw bytes within the ‘glyf’ table. For PostScript formats, it must correspond to the unencrypted charstring bytes, without any ‘lenIV’ header. It is undefined for any other format.

    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    If this function returns successfully the method FT_Incremental_FreeGlyphDataFunc will be called later to release the data bytes.

    -

    Nested calls to FT_Incremental_GetGlyphDataFunc can happen for compound glyphs.

    -
    -

    A structure to be used with FT_Open_Face to indicate that the user wants to support incremental glyph loading. You should use it with FT_PARAM_TAG_INCREMENTAL as in the following example:

    -
    -  FT_Incremental_InterfaceRec  inc_int;
    -  FT_Parameter                 parameter;
    -  FT_Open_Args                 open_args;
    -
    -
    -  // set up incremental descriptor
    -  inc_int.funcs  = my_funcs;
    -  inc_int.object = my_object;
    -
    -  // set up optional parameter
    -  parameter.tag  = FT_PARAM_TAG_INCREMENTAL;
    -  parameter.data = &inc_int;
    -
    -  // set up FT_Open_Args structure
    -  open_args.flags      = FT_OPEN_PATHNAME | FT_OPEN_PARAMS;
    -  open_args.pathname   = my_font_pathname;
    -  open_args.num_params = 1;
    -  open_args.params     = &parameter; // we use one optional argument
    -
    -  // open the font
    -  error = FT_Open_Face( library, &open_args, index, &face );

    FT_LcdFilterFT_Library_SetLcdFilter


    - -
    -

    The FT_Library_SetLcdFilter API can be used to specify a low-pass filter which is then applied to LCD-optimized bitmaps generated through FT_Render_Glyph. This is useful to reduce color fringes which would occur with unfiltered rendering.

    -

    Note that no filter is active by default, and that this function is not implemented in default builds of the library. You need to #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your ‘ftoption.h’ file in order to activate it.

    FT_LcdFilter

    -  {
    -    FT_LCD_FILTER_NONE    = 0,
    -    FT_LCD_FILTER_DEFAULT = 1,

    -

    A list of values to identify various types of LCD filters.

    -

    -
    values
    -

    - - - - - -
    FT_LCD_FILTER_NONE -

    Do not perform filtering. When used with subpixel rendering, this results in sometimes severe color fringes.

    -
    FT_LCD_FILTER_DEFAULT -

    The default filter reduces color fringes considerably, at the cost of a slight blurriness in the output.

    -
    FT_LCD_FILTER_LIGHT -

    The light filter is a variant that produces less blurriness at the cost of slightly more color fringes than the default one. It might be better, depending on taste, your monitor, or your personal vision.

    -
    FT_LCD_FILTER_LEGACY -

    This filter corresponds to the original libXft color filter. It provides high contrast output but can exhibit really bad color fringes if glyphs are not extremely well hinted to the pixel grid. In other words, it only works well if the TrueType bytecode interpreter is enabled and high-quality hinted fonts are used.

    -

    This filter is only provided for comparison purposes, and might be disabled or stay unsupported in the future.

    FT_Library_SetLcdFilter

    -
    -Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h). -

    -
    -
    -  FT_EXPORT( FT_Error )
    -  FT_Library_SetLcdFilter( FT_Library    library,
    -                           FT_LcdFilter  filter );
    -
    -

    -
    -

    This function is used to apply color filtering to LCD decimated bitmaps, like the ones used when calling FT_Render_Glyph with FT_RENDER_MODE_LCD or FT_RENDER_MODE_LCD_V.

    -

    -
    input
    -

    - - - -
    library -

    A handle to the target library instance.

    -
    filter -

    The filter type.

    -

    You can use FT_LCD_FILTER_NONE here to disable this feature, or FT_LCD_FILTER_DEFAULT to use a default filter that should work well on most LCD screens.

    -
    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    This feature is always disabled by default. Clients must make an explicit call to this function with a ‘filter’ value other than FT_LCD_FILTER_NONE in order to enable it.

    -

    Due to PATENTS covering subpixel rendering, this function doesn't do anything except returning ‘FT_Err_Unimplemented_Feature’ if the configuration macro FT_CONFIG_OPTION_SUBPIXEL_RENDERING is not defined in your build of the library, which should correspond to all default builds of FreeType.

    -

    The filter affects glyph bitmaps rendered through FT_Render_Glyph, FT_Outline_Get_Bitmap, FT_Load_Glyph, and FT_Load_Char.

    -

    It does not affect the output of FT_Outline_Render and FT_Outline_Get_Bitmap.

    -

    If this feature is activated, the dimensions of LCD glyph bitmaps are either larger or taller than the dimensions of the corresponding outline with regards to the pixel grid. For example, for FT_RENDER_MODE_LCD, the filter adds up to 3 pixels to the left, and up to 3 pixels to the right.

    -

    The bitmap offset values are adjusted correctly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.

    -
    -

    -
    -

    Open a new stream to parse LZW-compressed font files. This is mainly used to support the compressed ‘*.pcf.Z’ fonts that come with XFree86.

    -

    -
    input
    -

    - - - -
    stream -

    The target embedding stream.

    -
    source -

    The source stream.

    -
    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    The source stream must be opened before calling this function.

    -

    Calling the internal function ‘FT_Stream_Close’ on the new stream will not call ‘FT_Stream_Close’ on the source stream. None of the stream objects will be released to the heap.

    -

    The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream

    -

    In certain builds of the library, LZW compression recognition is automatically handled when calling FT_New_Face or FT_Open_Face. This means that if no font driver is capable of handling the raw compressed file, the library will try to open a LZW stream from it and re-open the face with it.

    -

    This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with LZW support.

    This function can be used to create FT_Face objects from fonts that are installed in the system as follows.

    -
    -  fond = GetResource( 'FOND', fontName );                          
    -  error = FT_New_Face_From_FOND( library, fond, 0, &face );

    input
    -

    - - - -
    hook_index -

    The index of the debug hook. You should use the values defined in ‘ftobjs.h’, e.g., ‘FT_DEBUG_HOOK_TRUETYPE’.

    -
    debug_hook -

    The function used to debug the interpreter.

    -
    -
    -
    note
    -

    Currently, four debug hook slots are available, but only two (for the TrueType and the Type 1 interpreter) are defined.

    -

    Since the internal headers of FreeType are no longer installed, the symbol ‘FT_DEBUG_HOOK_TRUETYPE’ isn't available publicly. This is a bug and will be fixed in a forthcoming release.

    The following types and functions are used to manage Multiple Master fonts, i.e., the selection of specific design instances by setting design axis coordinates.

    -

    George Williams has extended this interface to make it work with both Type 1 Multiple Masters fonts and GX distortable (var) fonts. Some of these routines only work with MM fonts, others will work with both types. They are similar enough that a consistent interface makes sense.

    -
    num_namedstyles -

    The number of named styles; only meaningful for GX which allows certain design coordinates to have a string ID (in the ‘name’ table) associated with them. The font can tell the user that, for example, Weight=1.5 is ‘Bold’.

    -  typedef struct  FT_Outline_
    -  {

    -
    -

    -
    -

    This structure is used to describe an outline to the scan-line converter.

    -

    -
    fields
    -

    - - - - - - - -
    n_contours -

    The number of contours in the outline.

    -
    n_points -

    The number of points in the outline.

    -
    points -

    A pointer to an array of ‘n_points’ FT_Vector elements, giving the outline's point coordinates.

    -
    tags -

    A pointer to an array of ‘n_points’ chars, giving each outline point's type.

    -

    If bit 0 is unset, the point is ‘off’ the curve, i.e., a Bézier control point, while it is ‘on’ if set.

    -

    Bit 1 is meaningful for ‘off’ points only. If set, it indicates a third-order Bézier arc control point; and a second-order control point if unset.

    -

    If bit 2 is set, bits 5-7 contain the drop-out mode (as defined in the OpenType specification; the value is the same as the argument to the SCANMODE instruction).

    -

    Bits 3 and 4 are reserved for internal purposes.

    -
    contours -

    An array of ‘n_contours’ shorts, giving the end point of each contour within the outline. For example, the first contour is defined by the points ‘0’ to ‘contours[0]’, the second one is defined by the points ‘contours[0]+1’ to ‘contours[1]’, etc.

    -
    flags -

    A set of bit flags used to characterize the outline and give hints to the scan-converter and hinter on how to convert/grid-fit it. See FT_OUTLINE_FLAGS.

    -
    -
    -
    note
    -

    The B/W rasterizer only checks bit 2 in the ‘tags’ array for the first point of each contour. The drop-out mode as given with FT_OUTLINE_IGNORE_DROPOUTS, FT_OUTLINE_SMART_DROPOUTS, and FT_OUTLINE_INCLUDE_STUBS in ‘flags’ is then overridden.

    A list of bit-field constants use for the flags in an outline's ‘flags’ field.

    -

    -
    values
    -

    - - - - - - - - - - - - - - - - -
    FT_OUTLINE_NONE -

    Value 0 is reserved.

    -
    FT_OUTLINE_OWNER -

    If set, this flag indicates that the outline's field arrays (i.e., ‘points’, ‘flags’, and ‘contours’) are ‘owned’ by the outline object, and should thus be freed when it is destroyed.

    -
    FT_OUTLINE_EVEN_ODD_FILL
    -

    By default, outlines are filled using the non-zero winding rule. If set to 1, the outline will be filled using the even-odd fill rule (only works with the smooth rasterizer).

    -
    FT_OUTLINE_REVERSE_FILL
    -

    By default, outside contours of an outline are oriented in clock-wise direction, as defined in the TrueType specification. This flag is set if the outline uses the opposite direction (typically for Type 1 fonts). This flag is ignored by the scan converter.

    -
    FT_OUTLINE_IGNORE_DROPOUTS
    -

    By default, the scan converter will try to detect drop-outs in an outline and correct the glyph bitmap to ensure consistent shape continuity. If set, this flag hints the scan-line converter to ignore such cases. See below for more information.

    -
    FT_OUTLINE_SMART_DROPOUTS
    -

    Select smart dropout control. If unset, use simple dropout control. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information.

    -
    FT_OUTLINE_INCLUDE_STUBS
    -

    If set, turn pixels on for ‘stubs’, otherwise exclude them. Ignored if FT_OUTLINE_IGNORE_DROPOUTS is set. See below for more information.

    -
    FT_OUTLINE_HIGH_PRECISION
    -

    This flag indicates that the scan-line converter should try to convert this outline to bitmaps with the highest possible quality. It is typically set for small character sizes. Note that this is only a hint that might be completely ignored by a given scan-converter.

    -
    FT_OUTLINE_SINGLE_PASS -

    This flag is set to force a given scan-converter to only use a single pass over the outline to render a bitmap glyph image. Normally, it is set for very large character sizes. It is only a hint that might be completely ignored by a given scan-converter.

    -
    -
    -
    note
    -

    The flags FT_OUTLINE_IGNORE_DROPOUTS, FT_OUTLINE_SMART_DROPOUTS, and FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer.

    -

    There exists a second mechanism to pass the drop-out mode to the B/W rasterizer; see the ‘tags’ field in FT_Outline.

    -

    Please refer to the description of the ‘SCANTYPE’ instruction in the OpenType specification (in file ‘ttinst1.doc’) how simple drop-outs, smart drop-outs, and stubs are defined.

    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    The used algorithm to increase or decrease the thickness of the glyph doesn't change the number of points; this means that certain situations like acute angles or intersections are sometimes handled incorrectly.

    -

    If you need ‘better’ metrics values you should call FT_Outline_Get_CBox ot FT_Outline_Get_BBox.

    Example call:

    -
    -  FT_Load_Glyph( face, index, FT_LOAD_DEFAULT );                   
    -  if ( face->slot->format == FT_GLYPH_FORMAT_OUTLINE )

    - - - - - - - -
    move_to -

    The ‘move to’ emitter.

    delta -

    The delta that is applied to coordinates before they are sent to the emitter, but after the shift.

    -
    -
    -
    note
    -

    The point coordinates sent to the emitters are the transformed version of the original coordinates (this is important for high accuracy during scan-conversion). The transformation is simple:

    -
    -  x' = (x << shift) - delta

    -
    -

    Set the values of ‘shift’ and ‘delta’ to 0 to get the original point coordinates.

    -
    -

    -
    -

    Return an outline's ‘control box’. The control box encloses all the outline's points, including Bézier control points. Though it coincides with the exact bounding box for most glyphs, it can be slightly larger in some situations (like when rotating an outline which contains Bézier outside arcs).

    -

    Computing the control box is very fast, while getting the bounding box can take much more time as it needs to walk over all segments and arcs in the outline. To get the latter, you can use the ‘ftbbox’ component which is dedicated to this single task.

    -

    -
    -
    note
    -

    This function does NOT CREATE the bitmap, it only renders an outline image within the one you pass to it! Consequently, the various fields in ‘abitmap’ should be set accordingly.

    -

    It will use the raster corresponding to the default glyph format.

    -

    The value of the ‘num_grays’ field in ‘abitmap’ is ignored. If you select the gray-level rasterizer, and you want less than 256 gray levels, you have to use FT_Outline_Render directly.

    -
    -

    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    You should know what you are doing and how FT_Raster_Params works to use this function.

    -

    The field ‘params.source’ will be set to ‘outline’ before the scan converter is called, which means that the value you give to it is actually ignored.

    -

    The gray-level rasterizer always uses 256 gray levels. If you want less gray levels, you have to provide your own span callback. See the FT_RASTER_FLAG_DIRECT value of the ‘flags’ field in the FT_Raster_Params structure for more details.

    values
    -

    - - - - - - - - - - -

    -

    According to the PostScript specification, counter-clockwise contours must be filled, and clockwise ones must be unfilled.

    -
    FT_ORIENTATION_FILL_RIGHT
    -

    This is identical to FT_ORIENTATION_TRUETYPE, but is used to remember that in TrueType, everything that is to the right of the drawing direction of a contour must be filled.

    -
    FT_ORIENTATION_FILL_LEFT
    -

    This is identical to FT_ORIENTATION_POSTSCRIPT, but is used to remember that in PostScript, everything that is to the left of the drawing direction of a contour must be filled.

    -
    FT_ORIENTATION_NONE -

    The orientation cannot be determined. That is, different parts of the glyph have different orientation.

    -
    -

    -
    -

    A bit-flag to be OR-ed with the ‘flags’ parameter of the FT_Get_Advance and FT_Get_Advances functions.

    -

    If set, it indicates that you want these functions to fail if the corresponding hinting mode or font driver doesn't allow for very quick advance computation.

    -

    Typically, glyphs which are either unscaled, unhinted, bitmapped, or light-hinted can have their advance width computed very quickly.

    -

    Normal and bytecode hinted modes, which require loading, scaling, and hinting of the glyph outline, are extremely slow by comparison.

    -
    fields
    -

    - - - - -
    x -

    The span's horizontal start position.

    -
    len -

    The span's length in pixels.

    -
    coverage -

    The span color/coverage, ranging from 0 (background) to 255 (foreground). Only used for anti-aliased rendering.

    -
    -
    -
    note
    -

    This structure is used by the span drawing callback type named FT_SpanFunc which takes the y coordinate of the span as a a parameter.

    -

    The coverage value is always between 0 and 255. If you want less gray values, the callback function has to reduce them.

    -
    -#define FT_Raster_Span_Func  FT_SpanFunc
    -
    -

    -
    -

    A function used as a call-back by the anti-aliased renderer in order to let client applications draw themselves the gray pixel spans on each scan line.

    -

    -
    input
    -

    - - - - - -
    y -

    The scanline's y coordinate.

    -
    count -

    The number of spans to draw on this scanline.

    -
    spans -

    A table of ‘count’ spans to draw on the scanline.

    -
    user -

    User-supplied data that is passed to the callback.

    -
    -
    -
    note
    -

    This callback allows client applications to directly render the gray spans of the anti-aliased bitmap to any kind of surfaces.

    -

    This can be used to write anti-aliased outlines directly to a given background bitmap, and even perform translucency.

    -

    Note that the ‘count’ field cannot be greater than a fixed value defined by the ‘FT_MAX_GRAY_SPANS’ configuration macro in ‘ftoption.h’. By default, this value is set to 32, which means that if there are more than 32 spans on a given scanline, the callback is called several times with the same ‘y’ parameter in order to draw all callbacks.

    -

    Otherwise, the callback is only called once per scan-line, and only for those scanlines that do have ‘gray’ pixels on them.

    FT_RASTER_FLAG_DEFAULT -

    This value is 0.

    -
    FT_RASTER_FLAG_AA -

    This flag is set to indicate that an anti-aliased glyph image should be generated. Otherwise, it will be monochrome (1-bit).

    -
    FT_RASTER_FLAG_DIRECT -

    This flag is set to indicate direct rendering. In this mode, client applications must provide their own span callback. This lets them directly draw or compose over an existing bitmap. If this bit is not set, the target pixmap's buffer must be zeroed before rendering.

    -

    Note that for now, direct rendering is only possible with anti-aliased glyphs.

    -
    FT_RASTER_FLAG_CLIP -

    This flag is only used in direct rendering mode. If set, the output will be clipped to a box specified in the ‘clip_box’ field of the FT_Raster_Params structure.

    -

    Note that by default, the glyph bitmap is clipped to the target pixmap, except in direct rendering mode where all spans are generated if no clipping box is set.

    user -

    User-supplied data that is passed to each drawing callback.

    -
    clip_box -

    An optional clipping box. It is only used in direct rendering mode. Note that coordinates here should be expressed in integer pixels (and not in 26.6 fixed-point units).

    -
    -
    -
    note
    -

    An anti-aliased glyph bitmap is drawn if the FT_RASTER_FLAG_AA bit flag is set in the ‘flags’ field, otherwise a monochrome bitmap is generated.

    -

    If the FT_RASTER_FLAG_DIRECT bit flag is set in ‘flags’, the raster will call the ‘gray_spans’ callback to draw gray pixel spans, in the case of an aa glyph bitmap, it will call ‘black_spans’, and ‘bit_test’ and ‘bit_set’ in the case of a monochrome bitmap. This allows direct composition over a pre-existing bitmap through user-provided callbacks to perform the span drawing/composition.

    -

    Note that the ‘bit_test’ and ‘bit_set’ callbacks are required when rendering a monochrome bitmap, as they are crucial to implement correct drop-out control as defined in the TrueType specification.

    The ‘memory’ parameter is a typeless pointer in order to avoid un-wanted dependencies on the rest of the FreeType code. In practice, it is an FT_Memory object, i.e., a handle to the standard FreeType memory allocator. However, this field can be completely ignored by a given raster implementation.

    FreeType provides an area of memory called the ‘render pool’, available to all registered rasters. This pool can be freely used during a given scan-conversion but is shared by all rasters. Its content is thus transient.

    -

    This function is called each time the render pool changes, or just after a new raster object is created.

    -
    pool_size -

    The size in bytes of the render pool.

    -
    -
    -
    note
    -

    Rasters can ignore the render pool and rely on dynamic memory allocation if they want to (a handle to the memory allocator is passed to the raster constructor). However, this is not recommended for efficiency purposes.

    -
    -#define FT_Raster_Render_Func  FT_Raster_RenderFunc
    -
    -

    -
    -

    Invoke a given raster to scan-convert a given glyph image into a target bitmap.

    - - - -
    raster -

    A handle to the raster object.

    -
    params -

    A pointer to an FT_Raster_Params structure used to store the rendering parameters.

    -
    -
    -
    return
    -

    Error code. 0 means success.

    -
    -
    note
    -

    The exact format of the source image depends on the raster's glyph format defined in its FT_Raster_Funcs structure. It can be an FT_Outline or anything else in order to support a large array of glyph formats.

    -

    Note also that the render function can fail and return a ‘FT_Err_Unimplemented_Feature’ error code if the raster used does not support direct composition.

    -

    XXX: For now, the standard raster doesn't support direct composition but this should change for the final release (see the files ‘demos/src/ftgrays.c’ and ‘demos/src/ftgrays2.c’ for examples of distinct implementations which support direct composition).

    FT_New_SizeFT_Done_SizeFT_Activate_Size


    - -
    -

    When creating a new face object (e.g., with FT_New_Face), an FT_Size object is automatically created and used to store all pixel-size dependent information, available in the ‘face->size’ field.

    -

    It is however possible to create more sizes for a given face, mostly in order to manage several character pixel sizes of the same font family and style. See FT_New_Size and FT_Done_Size.

    -

    Note that FT_Set_Pixel_Sizes and FT_Set_Char_Size only modify the contents of the current ‘active’ size; you thus need to use FT_Activate_Size to change it.

    -

    99% of applications won't need the functions provided here, especially if they use the caching sub-system, so be cautious when using these.

    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    You need to call FT_Activate_Size in order to select the new size for upcoming calls to FT_Set_Pixel_Sizes, FT_Set_Char_Size, FT_Load_Glyph, FT_Load_Char, etc.

    -

    -
    -

    Even though it is possible to create several size objects for a given face (see FT_New_Size for details), functions like FT_Load_Glyph or FT_Load_Char only use the one which has been activated last to determine the ‘current character pixel size’.

    -

    This function can be used to ‘activate’ a previously created size object.

    -

    -
    input
    -

    A handle to a target size object.

    -

    FreeType error code. 0 means success.

    -

    The stream's input function.

    -
    close -

    The stream;s close function.

    -
    memory -

    The memory manager to use to preload frames. This is set internally by FreeType and shouldn't be touched by stream implementations.

    -
    cursor -

    This field is set and used internally by FreeType when parsing frames.

    -
    limit -

    This field is set and used internally by FreeType when parsing frames.

    -
    values
    -

    - - - - - - - -
    FT_TRUETYPE_ENGINE_TYPE_NONE
    -

    The library doesn't implement any kind of bytecode interpreter.

    -
    FT_TRUETYPE_ENGINE_TYPE_UNPATENTED
    -

    The library implements a bytecode interpreter that doesn't support the patented operations of the TrueType virtual machine.

    -

    Its main use is to load certain Asian fonts which position and scale glyph components with bytecode instructions. It produces bad output for most other fonts.

    -
    FT_TRUETYPE_ENGINE_TYPE_PATENTED
    -

    The library implements a bytecode interpreter that covers the full instruction set of the TrueType virtual machine. See the file ‘docs/PATENTS’ for legal aspects.

    Used by Apple to indicate a MacOS-specific charmap and/or name entry. See TT_MAC_ID_XXX for corresponding ‘encoding_id’ values. Note that most TrueType fonts contain an Apple roman charmap to be usable on MacOS systems (even if they contain a Microsoft charmap as well).

    -
    TT_PLATFORM_ISO -

    This value was used to specify Unicode charmaps. It is however now deprecated. See TT_ISO_ID_XXX for a list of corresponding ‘encoding_id’ values.

    -
    TT_PLATFORM_MICROSOFT -

    Used by Microsoft to indicate Windows-specific charmaps. See TT_MS_ID_XXX for a list of corresponding ‘encoding_id’ values. Note that most fonts contain a Unicode charmap using (TT_PLATFORM_MICROSOFT, TT_MS_ID_UNICODE_CS).

    -
    TT_PLATFORM_CUSTOM -

    Used to indicate application-specific charmaps.

    -
    TT_PLATFORM_ADOBE -

    This value isn't part of any font format specification, but is used by FreeType to report Adobe-specific charmaps in an FT_CharMapRec structure. See TT_ADOBE_ID_XXX.

    fields
    -

    - - - - - - - - - - - - - - - - -
    Version -

    The table version.

    -
    Ascender -

    The font's ascender, i.e., the distance from the baseline to the top-most of all glyph points found in the font.

    -

    This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).

    -

    You should use the ‘sTypoAscender’ field of the OS/2 table instead if you want the correct one.

    -
    Descender -

    The font's descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font. It is negative.

    -

    This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII).

    -

    You should use the ‘sTypoDescender’ field of the OS/2 table instead if you want the correct one.

    -
    Line_Gap -

    The font's line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.

    -
    advance_Width_Max -

    This field is the maximum of all advance widths found in the font. It can be used to compute the maximum width of an arbitrary string of text.

    -
    min_Left_Side_Bearing -

    The minimum left side bearing of all glyphs within the font.

    -
    min_Right_Side_Bearing -

    The minimum right side bearing of all glyphs within the font.

    -
    xMax_Extent -

    The maximum horizontal extent (i.e., the ‘width’ of a glyph's bounding box) for all glyphs in the font.

    -
    caret_Slope_Rise -

    The rise coefficient of the cursor's slope of the cursor (slope=rise/run).

    -
    caret_Slope_Run -

    The run coefficient of the cursor's slope.

    -
    Reserved -

    8 reserved bytes.

    -
    metric_Data_Format -

    Always 0.

    -
    number_Of_HMetrics -

    Number of HMetrics entries in the ‘hmtx’ table -- this value can be smaller than the total number of glyphs in the font.

    -
    long_metrics -

    A pointer into the ‘hmtx’ table.

    -
    short_metrics -

    A pointer into the ‘hmtx’ table.

    -
    -
    -
    note
    -

    IMPORTANT: The TT_HoriHeader and TT_VertHeader structures should be identical except for the names of their fields which are different.

    -

    This ensures that a single function in the ‘ttload’ module is able to read both the horizontal and vertical headers.

    -                      FT_ULong*  length );
    -
    -

    -
    -

    Load any font table into client memory.

    -

    -
    input
    -

    - - - - -
    face -

    A handle to the source face.

    -
    tag -

    The four-byte tag of the table to load. Use the value 0 if you want to access the whole font file. Otherwise, you can use one of the definitions found in the FT_TRUETYPE_TAGS_H file, or forge a new one with FT_MAKE_TAG.

    -
    offset -

    The starting offset in the table (or file if tag == 0).

    -
    -
    -
    output
    -

    - - -
    buffer -

    The target buffer address. The client must ensure that the memory array is big enough to hold the data.

    -
    -
    -
    inout
    -

    - - -
    length -

    If the ‘length’ parameter is NULL, then try to load the whole table. Return an error code if it fails.

    -

    Else, if ‘*length’ is 0, exit immediately while returning the table's (or file) full size in it.

    -

    Else the number of bytes to read from the table or file, from the starting offset.

    -
    -
    -
    return
    -

    FreeType error code. 0 means success.

    -
    -
    note
    -

    If you need to determine the table's length you should first call this function with ‘*length’ set to 0, as in the following example:

    -
    -  FT_ULong  length = 0;
    -
    -
    -  error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );
    -  if ( error ) { ... table does not exist ... }
    -
    -  buffer = malloc( length );
    -  if ( buffer == NULL ) { ... not enough memory ... }
    -
    -  error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );
    -  if ( error ) { ... could not load table ... }

    -User allocation -

    -
    -

    FreeType assumes that structures allocated by the user and passed as arguments are zeroed out except for the actual data. In other words, it is recommended to use ‘calloc’ (or variants of it) instead of ‘malloc’ for allocation.

    values
    -

    - - - - -
    FREETYPE_MAJOR -

    The major version number.

    -
    FREETYPE_PATCH -

    The patch level.

    -

    -
    -

    Return the version of the FreeType library being used. This is useful when dynamically linking to the library, since one cannot use the macros FREETYPE_MAJOR, FREETYPE_MINOR, and FREETYPE_PATCH.

    -

    -
    input

    -
    apatch -

    The patch version number.

    -
    -
    -
    note
    -

    The reason why this function takes a ‘library’ argument is because certain programs implement library initialization in a custom way that doesn't use FT_Init_FreeType.

    -

    In such cases, the library version might not be available before the library object has been created.

    Parse all bytecode instructions of a TrueType font file to check whether any of the patented opcodes are used. This is only useful if you want to be able to use the unpatented hinter with fonts that do not use these opcodes.

    -

    Note that this function parses all glyph instructions in the font file, which may be slow.

    FT_WinFNT_ID_DEFAULT -

    This is used for font enumeration and font creation as a ‘don't care’ value. Valid font files don't contain this value. When querying for information about the character set of the font that is currently selected into a specified device context, this return value (of the related Windows API) simply denotes failure.

    -
    FT_WinFNT_ID_SYMBOL -

    There is no known mapping table available.

    FT_WinFNT_ID_MAC -

    Mac Roman encoding.

    -
    FT_WinFNT_ID_OEM -

    From Michael Pöttgen <michael@poettgen.de>:

    -

    The ‘Windows Font Mapping’ article says that FT_WinFNT_ID_OEM is used for the charset of vector fonts, like ‘modern.fon’, ‘roman.fon’, and ‘script.fon’ on Windows.

    -

    The ‘CreateFont’ documentation says: The FT_WinFNT_ID_OEM value specifies a character set that is operating-system dependent.

    -

    The ‘IFIMETRICS’ documentation from the ‘Windows Driver Development Kit’ says: This font supports an OEM-specific character set. The OEM character set is system dependent.

    -

    In general OEM, as opposed to ANSI (i.e., cp1252), denotes the second default codepage that most international versions of Windows have. It is one of the OEM codepages from

    -

    http://www.microsoft.com/globaldev/reference/cphome.mspx,

    and is used for the ‘DOS boxes’, to support legacy applications. A German Windows version for example usually uses ANSI codepage 1252 and OEM codepage 850.

In this case, the following happens: + * + * 1. FreeType looks for a bitmap for the glyph corresponding to the + * face's current size. If one is found, the function returns. + * The bitmap data can be accessed from the glyph slot (see note + * below). + * + * 2. If no embedded bitmap is searched or found, FreeType looks for a + * scalable outline. If one is found, it is loaded from the font + * file, scaled to device pixels, then `hinted' to the pixel grid + * in order to optimize it. The outline data can be accessed from + * the glyph slot (see note below). + * + * Note that by default, the glyph loader doesn't render outlines into + * bitmaps. The following flags are used to modify this default + * behaviour to more specific and useful cases. + * + * FT_LOAD_NO_SCALE :: + * Don't scale the loaded outline glyph but keep it in font units. + * + * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and + * unsets @FT_LOAD_RENDER. + * + * If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using + * FT_LOAD_NO_SCALE usually yields meaningless outlines because the + * subglyphs must be scaled and positioned with hinting instructions. + * This can be solved by loading the font without FT_LOAD_NO_SCALE and + * setting the character size to `font->units_per_EM'. + * + * FT_LOAD_NO_HINTING :: + * Disable hinting. This generally generates `blurrier' bitmap glyphs + * when the glyph are rendered in any of the anti-aliased modes. See + * also the note below. + * + * This flag is implied by @FT_LOAD_NO_SCALE. + * + * FT_LOAD_RENDER :: + * Call @FT_Render_Glyph after the glyph is loaded. By default, the + * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be + * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME. + * + * This flag is unset by @FT_LOAD_NO_SCALE. + * + * FT_LOAD_NO_BITMAP :: + * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this + * flag. + * + * @FT_LOAD_NO_SCALE always sets this flag. + * + * FT_LOAD_VERTICAL_LAYOUT :: + * Load the glyph for vertical text layout. In particular, the + * `advance' value in the @FT_GlyphSlotRec structure is set to the + * `vertAdvance' value of the `metrics' field. + * + * In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use + * this flag currently. Reason is that in this case vertical metrics + * get synthesized, and those values are not always consistent across + * various font formats. + * + * FT_LOAD_FORCE_AUTOHINT :: + * Indicates that the auto-hinter is preferred over the font's native + * hinter. See also the note below. + * + * FT_LOAD_PEDANTIC :: + * Indicates that the font driver should perform pedantic verifications + * during glyph loading. This is mostly used to detect broken glyphs + * in fonts. By default, FreeType tries to handle broken fonts also. + * + * In particular, errors from the TrueType bytecode engine are not + * passed to the application if this flag is not set; this might + * result in partially hinted or distorted glyphs in case a glyph's + * bytecode is buggy. + * + * FT_LOAD_NO_RECURSE :: + * Indicate that the font driver should not load composite glyphs + * recursively. Instead, it should set the `num_subglyph' and + * `subglyphs' values of the glyph slot accordingly, and set + * `glyph->format' to @FT_GLYPH_FORMAT_COMPOSITE. The description of + * subglyphs can then be accessed with @FT_Get_SubGlyph_Info. + * + * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM. + * + * FT_LOAD_IGNORE_TRANSFORM :: + * Indicates that the transform matrix set by @FT_Set_Transform should + * be ignored. + * + * FT_LOAD_MONOCHROME :: + * This flag is used with @FT_LOAD_RENDER to indicate that you want to + * render an outline glyph to a 1-bit monochrome bitmap glyph, with + * 8~pixels packed into each byte of the bitmap data. + * + * Note that this has no effect on the hinting algorithm used. You + * should rather use @FT_LOAD_TARGET_MONO so that the + * monochrome-optimized hinting algorithm is used. + * + * FT_LOAD_LINEAR_DESIGN :: + * Indicates that the `linearHoriAdvance' and `linearVertAdvance' + * fields of @FT_GlyphSlotRec should be kept in font units. See + * @FT_GlyphSlotRec for details. + * + * FT_LOAD_NO_AUTOHINT :: + * Disable auto-hinter. See also the note below. + * + * FT_LOAD_COLOR :: + * This flag is used to request loading of color embedded-bitmap + * images. The resulting color bitmaps, if available, will have the + * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color + * bitmaps are found, they will be converted to 256-level gray + * bitmaps transparently.

The following flags are used to modify this default - * behaviour to more specific and useful cases. - * - * FT_LOAD_NO_SCALE :: - * Don't scale the outline glyph loaded, but keep it in font units. - * - * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and - * unsets @FT_LOAD_RENDER. - * - * FT_LOAD_NO_HINTING :: - * Disable hinting. This generally generates `blurrier' bitmap glyph - * when the glyph is rendered in any of the anti-aliased modes. See - * also the note below. - * - * This flag is implied by @FT_LOAD_NO_SCALE. - * - * FT_LOAD_RENDER :: - * Call @FT_Render_Glyph after the glyph is loaded. By default, the - * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be - * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME. - * - * This flag is unset by @FT_LOAD_NO_SCALE. - * - * FT_LOAD_NO_BITMAP :: - * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this - * flag. - * - * @FT_LOAD_NO_SCALE always sets this flag. - * - * FT_LOAD_VERTICAL_LAYOUT :: - * Load the glyph for vertical text layout. _Don't_ use it as it is - * problematic currently. - * - * FT_LOAD_FORCE_AUTOHINT :: - * Indicates that the auto-hinter is preferred over the font's native - * hinter. See also the note below. - * - * FT_LOAD_CROP_BITMAP :: - * Indicates that the font driver should crop the loaded bitmap glyph - * (i.e., remove all space around its black bits). Not all drivers - * implement this. - * - * FT_LOAD_PEDANTIC :: - * Indicates that the font driver should perform pedantic verifications - * during glyph loading. This is mostly used to detect broken glyphs - * in fonts. By default, FreeType tries to handle broken fonts also. - * - * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: - * Indicates that the font driver should ignore the global advance - * width defined in the font. By default, that value is used as the - * advance width for all glyphs when the face has - * @FT_FACE_FLAG_FIXED_WIDTH set. - * - * This flag exists for historical reasons (to support buggy CJK - * fonts). - * - * FT_LOAD_NO_RECURSE :: - * This flag is only used internally. It merely indicates that the - * font driver should not load composite glyphs recursively. Instead, - * it should set the `num_subglyph' and `subglyphs' values of the - * glyph slot accordingly, and set `glyph->format' to - * @FT_GLYPH_FORMAT_COMPOSITE. - * - * The description of sub-glyphs is not available to client - * applications for now. - * - * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM. - * - * FT_LOAD_IGNORE_TRANSFORM :: - * Indicates that the transform matrix set by @FT_Set_Transform should - * be ignored. - * - * FT_LOAD_MONOCHROME :: - * This flag is used with @FT_LOAD_RENDER to indicate that you want to - * render an outline glyph to a 1-bit monochrome bitmap glyph, with - * 8~pixels packed into each byte of the bitmap data. - * - * Note that this has no effect on the hinting algorithm used. You - * should rather use @FT_LOAD_TARGET_MONO so that the - * monochrome-optimized hinting algorithm is used. - * - * FT_LOAD_LINEAR_DESIGN :: - * Indicates that the `linearHoriAdvance' and `linearVertAdvance' - * fields of @FT_GlyphSlotRec should be kept in font units. See - * @FT_GlyphSlotRec for details. - * - * FT_LOAD_NO_AUTOHINT :: - * Disable auto-hinter. See also the note below. - * - * @note: - * By default, hinting is enabled and the font's native hinter (see - * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can - * disable hinting by setting @FT_LOAD_NO_HINTING or change the - * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set - * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be - * used at all. - * - * See the description of @FT_FACE_FLAG_TRICKY for a special exception - * (affecting only a handful of Asian fonts). - * - * Besides deciding which hinter to use, you can also decide which - * hinting algorithm to use.

This implies - * the following scheme: - * - * First, available or installed font faces are uniquely identified by - * @FTC_FaceID values, provided to the cache by the client. Note that - * the cache only stores and compares these values, and doesn't try to - * interpret them in any way. - * - * Second, the cache calls, only when needed, a client-provided function - * to convert a @FTC_FaceID into a new @FT_Face object. The latter is - * then completely managed by the cache, including its termination - * through @FT_Done_Face. - * - * Clients are free to map face IDs to anything else. The most simple - * usage is to associate them to a (pathname,face_index) pair that is - * used to call @FT_New_Face.

Failure to do so will lead to incorrect behaviour - * or even crashes. - * - * To use the cache, start with calling @FTC_Manager_New to create a new - * @FTC_Manager object, which models a single cache instance. You can - * then look up @FT_Face and @FT_Size objects with - * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively. - * - * If you want to use the charmap caching, call @FTC_CMapCache_New, then - * later use @FTC_CMapCache_Lookup to perform the equivalent of - * @FT_Get_Char_Index, only much faster. - * - * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then - * later use @FTC_ImageCache_Lookup to retrieve the corresponding - * @FT_Glyph objects from the cache. - * - * If you need lots of small bitmaps, it is much more memory efficient - * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This - * returns @FTC_SBitRec structures, which are used to store small - * bitmaps directly.

This implies + * the following scheme: + * + * First, available or installed font faces are uniquely identified by + * @FTC_FaceID values, provided to the cache by the client. Note that + * the cache only stores and compares these values, and doesn't try to + * interpret them in any way. + * + * Second, the cache calls, only when needed, a client-provided function + * to convert an @FTC_FaceID into a new @FT_Face object. The latter is + * then completely managed by the cache, including its termination + * through @FT_Done_Face. To monitor termination of face objects, the + * finalizer callback in the `generic' field of the @FT_Face object can + * be used, which might also be used to store the @FTC_FaceID of the + * face. + * + * Clients are free to map face IDs to anything else. The most simple + * usage is to associate them to a (pathname,face_index) pair that is + * used to call @FT_New_Face. However, more complex schemes are also + * possible. + * + * Note that for the cache to work correctly, the face ID values must be + * *persistent*, which means that the contents they point to should not + * change at runtime, or that their value should not become invalid. + * + * If this is unavoidable (e.g., when a font is uninstalled at runtime), + * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let + * the cache get rid of any references to the old @FTC_FaceID it may + * keep internally. Failure to do so will lead to incorrect behaviour + * or even crashes. + * + * To use the cache, start with calling @FTC_Manager_New to create a new + * @FTC_Manager object, which models a single cache instance. You can + * then look up @FT_Face and @FT_Size objects with + * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively. + * + * If you want to use the charmap caching, call @FTC_CMapCache_New, then + * later use @FTC_CMapCache_Lookup to perform the equivalent of + * @FT_Get_Char_Index, only much faster. + * + * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then + * later use @FTC_ImageCache_Lookup to retrieve the corresponding + * @FT_Glyph objects from the cache. + * + * If you need lots of small bitmaps, it is much more memory efficient + * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This + * returns @FTC_SBitRec structures, which are used to store small + * bitmaps directly. (A small bitmap is one whose metrics and + * dimensions all fit into 8-bit integers). + * + * We hope to also provide a kerning cache in the near future. + * + * + * <Order> + * FTC_Manager + * FTC_FaceID + * FTC_Face_Requester + * + * FTC_Manager_New + * FTC_Manager_Reset + * FTC_Manager_Done + * FTC_Manager_LookupFace + * FTC_Manager_LookupSize + * FTC_Manager_RemoveFaceID + * + * FTC_Node + * FTC_Node_Unref + * + * FTC_ImageCache + * FTC_ImageCache_New + * FTC_ImageCache_Lookup + * + * FTC_SBit + * FTC_SBitCache + * FTC_SBitCache_New + * FTC_SBitCache_Lookup + * + * FTC_CMapCache + * FTC_CMapCache_New + * FTC_CMapCache_Lookup + * + *************************************************************************/ + + + /*************************************************************************/ + /*************************************************************************/ + /*************************************************************************/ + /***** *****/ + /***** BASIC TYPE DEFINITIONS *****/ + /***** *****/ + /*************************************************************************/ + /*************************************************************************/ + /*************************************************************************/ + + + /************************************************************************* + * + * @type: FTC_FaceID + * + * @description: + * An opaque pointer type that is used to identity face objects.

The list below gives the available properties + * together with the necessary macros and structures. + * + * The CFF driver's module name is `cff'. + * + * *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine* + * + * The rasterizer is positioning horizontal features (e.g., ascender + * height & x-height, or crossbars) on the pixel grid and minimizing the + * amount of antialiasing applied to them, while placing vertical + * features (vertical stems) on the pixel grid without hinting, thus + * representing the stem position and weight accurately. Sometimes the + * vertical stems may be only partially black. In this context, + * `antialiasing' means that stems are not positioned exactly on pixel + * borders, causing a fuzzy appearance. + * + * There are two principles behind this approach. + * + * 1) No hinting in the horizontal direction: Unlike `superhinted' + * TrueType, which changes glyph widths to accommodate regular + * inter-glyph spacing, Adobe's approach is `faithful to the design' in + * representing both the glyph width and the inter-glyph spacing + * designed for the font. This makes the screen display as close as it + * can be to the result one would get with infinite resolution, while + * preserving what is considered the key characteristics of each glyph. + * Note that the distances between unhinted and grid-fitted positions at + * small sizes are comparable to kerning values and thus would be + * noticeable (and distracting) while reading if hinting were applied. + * + * One of the reasons to not hint horizontally is antialiasing for LCD + * screens: The pixel geometry of modern displays supplies three + * vertical sub-pixels as the eye moves horizontally across each visible + * pixel. On devices where we can be certain this characteristic is + * present a rasterizer can take advantage of the sub-pixels to add + * increments of weight. In Western writing systems this turns out to + * be the more critical direction anyway; the weights and spacing of + * vertical stems (see above) are central to Armenian, Cyrillic, Greek, + * and Latin type designs. Even when the rasterizer uses greyscale + * antialiasing instead of color (a necessary compromise when one + * doesn't know the screen characteristics), the unhinted vertical + * features preserve the design's weight and spacing much better than + * aliased type would. + * + * 2) Aligment in the vertical direction: Weights and spacing along the + * y~axis are less critical; what is much more important is the visual + * alignment of related features (like cap-height and x-height). The + * sense of alignment for these is enhanced by the sharpness of grid-fit + * edges, while the cruder vertical resolution (full pixels instead of + * 1/3 pixels) is less of a problem. + * + * On the technical side, horizontal alignment zones for ascender, + * x-height, and other important height values (traditionally called + * `blue zones') as defined in the font are positioned independently, + * each being rounded to the nearest pixel edge, taking care of + * overshoot suppression at small sizes, stem darkening, and scaling. + * + * Hstems (this is, hint values defined in the font to help align + * horizontal features) that fall within a blue zone are said to be + * `captured' and are aligned to that zone. Uncaptured stems are moved + * in one of four ways, top edge up or down, bottom edge up or down. + * Unless there are conflicting hstems, the smallest movement is taken + * to minimize distortion. + * + * @order: + * hinting-engine + * no-stem-darkening + * darkening-parameters + * + */ + + + /************************************************************************** + * + * @property: + * hinting-engine + * + * @description: + * Thanks to Adobe, which contributed a new hinting (and parsing) + * engine, an application can select between `freetype' and `adobe' if + * compiled with CFF_CONFIG_OPTION_OLD_ENGINE.

The +// script then fills the corresponding templates (indicated by `@' +// characters around the name). +// +// A section contains one or more data records. Each data record consists +// of two or more lines. The first line holds the enumeration name, and the +// remaining lines the corresponding array data. +// +// There are two possible representations for array data. +// +// - A string of characters in UTF-8 encoding enclosed in double quotes, +// using C syntax. There can be only one string per line, thus the +// starting and ending double quote must be the first and last character +// in the line, respectively, ignoring whitespace before and after the +// string. Space characters within the string are ignored too. If there +// are multiple strings (in multiple lines), they are concatenated to a +// single string. In the output, a string gets represented as a series of +// singles bytes, followed by a zero byte. The enumeration values simply +// hold byte offsets to the start of the corresponding strings. +// +// - Data blocks enclosed in balanced braces, which get copied verbatim and +// which can span multiple lines. The opening brace of a block must be +// the first character of a line (ignoring whitespace), and the closing +// brace the last (ignoring whitespace also). The script appends a comma +// character after each block and counts the number of blocks to set the +// enumeration values. +// +// A section can contain either strings only or data blocks only. +// +// A comment line starts with `//'; it gets removed. A preprocessor +// directive line (using the standard syntax of `cpp') starts with `#' and +// gets copied verbatim to both the enumeration and the array. Whitespace +// outside of a string is insignificant. +// +// Preprocessor directives are ignored while the script computes maximum +// values; this essentially means that the maximum values can easily be too +// large. Given that the purpose of those values is to create local +// fixed-size arrays at compile time for further processing of the blue zone +// data, this isn't a problem.

Fixed bug when illegal slave address was passed to eMBInit - where the error was not detected. Fixed typo in the holding registers - where the frame for write multiple registers was parsed with the wrong - constants. The fix is not critical because the values matched. Fixed bug - in discrete input registers implementation where the frame was not parsed - correctly. Added new support for a CodeWarrior Coldfire port. - - Detailed notes: - - BUG (ALL): Modbus functions are compiled into the stack conditionally - by changing the MB_FUNC_XXX defines to either true(1) or false(0). - The defines for MB_FUNC_READ_HOLDING and MB_FUNC_WRITE_HOLDING - were wrong. - - BUG (ALL): eMBInit did not correctly check for addresses. Therefore - is was possible to start the Modbus stack with an address of 0 - or one > 247. - - BUG (ALL): eMBFuncWriteHoldingRegister should use - MB_PDU_FUNC_WRITE_MUL_ADDR_OFF and not MB_PDU_FUNC_READ_ADDR_OFF. - - BUG (ALL): eMBFuncReadDiscreteInputs calculated the number of discrete - registers to read wrong. - - FEATURE (ALL): Fixed some warnings in the code. - -2006-11-19 (REL_1_1_1) Christian Walter : - Notes: Fixed bug in Read/Write Multiple Registers function where - the registers addresses where calculated wrong. - Fixed bug in RTU and ASCII with the resource allocation in case of - an error. - Changed license to BSD style licsense. - - Detailed notes: - - OTHER (ALL): License is now BSD for protocol stack. - - BUG (ALL): The registers address received in a Modbus frame - must be converted to application addresses. The code for this - conversion was missing and therefore has lead to error when - this function was used (Registers of by one, Start at > 1). - - BUG (ALL): If the serial initialization within the porting fails - a timer is still allocated in eMBRTUInit and eMBASCIIInit. This - can lead to a memory leak depending upon the implementation of the - porting layer. - - FEATURE (MCF5235): Added sample shell scripts for testing. - - FEATURE (MSP430): Added sample shell script for testing and - changed default values to match the other ports. - -2006-10-30 (REL_1_1_0) Christian Walter : - Notes: Added support for Read/Write Multiple Registers function - (0x17).

Correct behaviour - would be to wait till the end of frame. - Added new STR71X GCC port which uses only freely available tools - like GNU ARM, OpenOCD (Wiggler) and GDB. - - Detailed notes: - - FEATURE (STR71X): Added GCC standalone port which does not - depend on the Rowley Crosswork tools. - - FEATURE (ALL): eMBDisable can now be called multiple times - and returns MB_ENOERR in case is was already disabled. - eMBClose also supports beeing called multiple times in - which pvMBFrameCloseCur( ) is called when the protocol stack - is in state STATE_DISABLED. - - BUG (RTU): Fixed bug in xMBRTUReceiveFSM where the error - state is immediately left because of a missing break. Instead - we should wait till the damaged frame is finished. - -2006-10-11 (REL_1_0_4) Christian Walter : - Notes: Fixed bug when more than 255 coils are requested. Fixed bug in - Linux/Cygwin port when not all bytes could be written by the first - call to write. Added support for removing previously registered - function handlers. - - Detailed notes: - - BUG (ALL): mbfunccoils contained a bug which limited the amount - of coils to read to 255. - - BUG (LINUX): prvbMBPortSerialWrite contained a bug in the loop - which writes the RTU/ASCII frame to the serial file descriptor. - If not all bytes where written in the first call or write was - interrupted the sent frame is corrupted. - - FEATURE (ALL): eMBRegisterCB now supports NULL as handler - argument in which case a previously registered function - handler is deregistered from the protocol stack. - -2006-09-27 (REL_1_0_3) Christian Walter : - Notes: Added new functions to support registering of custom callback - handlers.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5.

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices.

If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this.

Fixed bug when illegal slave address was passed to eMBInit + where the error was not detected. Fixed typo in the holding registers + where the frame for write multiple registers was parsed with the wrong + constants. The fix is not critical because the values matched. Fixed bug + in discrete input registers implementation where the frame was not parsed + correctly. Added new support for a CodeWarrior Coldfire port. + + Detailed notes: + - BUG (ALL): Modbus functions are compiled into the stack conditionally + by changing the MB_FUNC_XXX defines to either true(1) or false(0). + The defines for MB_FUNC_READ_HOLDING and MB_FUNC_WRITE_HOLDING + were wrong. + - BUG (ALL): eMBInit did not correctly check for addresses. Therefore + is was possible to start the Modbus stack with an address of 0 + or one > 247. + - BUG (ALL): eMBFuncWriteHoldingRegister should use + MB_PDU_FUNC_WRITE_MUL_ADDR_OFF and not MB_PDU_FUNC_READ_ADDR_OFF. + - BUG (ALL): eMBFuncReadDiscreteInputs calculated the number of discrete + registers to read wrong. + - FEATURE (ALL): Fixed some warnings in the code. + +2006-11-19 (REL_1_1_1) Christian Walter : + Notes: Fixed bug in Read/Write Multiple Registers function where + the registers addresses where calculated wrong. + Fixed bug in RTU and ASCII with the resource allocation in case of + an error. + Changed license to BSD style licsense. + + Detailed notes: + - OTHER (ALL): License is now BSD for protocol stack. + - BUG (ALL): The registers address received in a Modbus frame + must be converted to application addresses. The code for this + conversion was missing and therefore has lead to error when + this function was used (Registers of by one, Start at > 1). + - BUG (ALL): If the serial initialization within the porting fails + a timer is still allocated in eMBRTUInit and eMBASCIIInit. This + can lead to a memory leak depending upon the implementation of the + porting layer. + - FEATURE (MCF5235): Added sample shell scripts for testing. + - FEATURE (MSP430): Added sample shell script for testing and + changed default values to match the other ports. + +2006-10-30 (REL_1_1_0) Christian Walter : + Notes: Added support for Read/Write Multiple Registers function + (0x17).

Correct behaviour + would be to wait till the end of frame. + Added new STR71X GCC port which uses only freely available tools + like GNU ARM, OpenOCD (Wiggler) and GDB. + + Detailed notes: + - FEATURE (STR71X): Added GCC standalone port which does not + depend on the Rowley Crosswork tools. + - FEATURE (ALL): eMBDisable can now be called multiple times + and returns MB_ENOERR in case is was already disabled. + eMBClose also supports beeing called multiple times in + which pvMBFrameCloseCur( ) is called when the protocol stack + is in state STATE_DISABLED. + - BUG (RTU): Fixed bug in xMBRTUReceiveFSM where the error + state is immediately left because of a missing break.

Fixed bug in + Linux/Cygwin port when not all bytes could be written by the first + call to write. Added support for removing previously registered + function handlers. + + Detailed notes: + - BUG (ALL): mbfunccoils contained a bug which limited the amount + of coils to read to 255. + - BUG (LINUX): prvbMBPortSerialWrite contained a bug in the loop + which writes the RTU/ASCII frame to the serial file descriptor. + If not all bytes where written in the first call or write was + interrupted the sent frame is corrupted. + - FEATURE (ALL): eMBRegisterCB now supports NULL as handler + argument in which case a previously registered function + handler is deregistered from the protocol stack. + +2006-09-27 (REL_1_0_3) Christian Walter : + Notes: Added new functions to support registering of custom callback + handlers.

GPRS or Analog). + + Detailed notes: + - FEATURES (AVR): Integrated patches from Tran Minh Hoang to support the + ATmega8, ATmega16, ATmega32, ATmega169 controllers. + - FEATURES (AVR): Added support for RS485 drivers in the AVR code. The + example supports the DS76176. + - FEATURES (STR71XTCP): implemented function in STR71X/lwIP porting layer + to remove running tasks. + - FEATURES (STR71XTCP): added new thread creation function in STR71X/lwIP + porting layer which allows specifing the stack size. + - BUGS (STR71XTCP): pppOpen defined in ppp.c does not check the return + value of sys_thread_new. If task creation fails the system crashes. + - BUGS (STR71XTCP): pppMain must not return - Instead it should remove + its task from the scheduler. + +2006-08-30 (REL_9) Christian Walter : + Notes: Added lwIP port for the MCF5235 target.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is +especially suitable for use in microcontrollers, but fits any memory +restricted system. + +Homepage: http://kapsi.fi/~jpa/nanopb/ + + + + +Using the nanopb library +======================== +To use the nanopb library, you need to do two things: + +1) Compile your .proto files for nanopb, using protoc. +2) Include pb_encode.c and pb_decode.c in your project. + +The easiest way to get started is to study the project in "examples/simple". +It contains a Makefile, which should work directly under most Linux systems. +However, for any other kind of build system, see the manual steps in +README.txt in that folder. + + + +Using the Protocol Buffers compiler (protoc) +============================================ +The nanopb generator is implemented as a plugin for the Google's own protoc +compiler.

However, it does mean that you need the +Google's protobuf library in order to run the generator. + +If you have downloaded a binary package for nanopb (either Windows, Linux or +Mac OS X version), the 'protoc' binary is included in the 'generator-bin' +folder. In this case, you are ready to go. Simply run this command: + + generator-bin/protoc --nanopb_out=. myprotocol.proto + +However, if you are using a git checkout or a plain source distribution, you +need to provide your own version of protoc and the Google's protobuf library. +On Linux, the necessary packages are protobuf-compiler and python-protobuf. +On Windows, you can either build Google's protobuf library from source or use +one of the binary distributions of it. In either case, if you use a separate +protoc, you need to manually give the path to nanopb generator: + + protoc --plugin=protoc-gen-nanopb=nanopb/generator/protoc-gen-nanopb ... + + + +Running the tests +================= +If you want to perform further development of the nanopb core, or to verify +its functionality using your compiler and platform, you'll want to run the +test suite. The build rules for the test suite are implemented using Scons, +so you need to have that installed. To run the tests: + + cd tests + scons + +This will show the progress of various test cases.
