Matthias Clasen ebe7e912 2023-01-02T20:13:22 [autofit] Don't depend on 'hb-ft'. The circular dependency is still there, but at least we no longer depend on the HarfBuzz API that is only present if HarfBuzz has been built with FreeType support, making the bootstrapping a bit easier. * src/autofit/ft-hb.c, src/autofit/ft-hb.h: New files, providing `_hb_ft_font_create`, which is more or less a verbatim copy of the corresponding HarfBuzz code from file `hb-ft.cc`. * src/autofit/afglobal.c (af_face_globals_new): Use it. * src/autofit/afshaper.h: Don't include `hb-ft.h` but `ft-hb.h`. * src/autofit/autofit.c: Include `ft-hb.c`. * LICENSE.TXT: Updated.

David Turner a212668c 2021-06-02T19:07:56 Remove obsolete AF_Angle type and related sources. Move the af_sort_xxx() functions from afangles.c to afhints.c in order to get rid of the obsolete angle-related types, macros and function definitions.
David Turner 2f11522a 2021-06-02T19:05:09 Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.
David Turner 15e88980 2021-06-02T18:54:41 Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2) This code has always been experimental and was never compiled anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even any of our build files).

Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Werner Lemberg 24aa9c66 2015-12-06T18:52:41 [autofit] Rewrite HarfBuzz interface to support character clusters. Scripts like Khmer have blue zones that can't be directly represented by Unicode characters. Instead, it is necessary to let HarfBuzz convert character clusters into proper glyph representation forms, then deriving the blue zone information from the resulting glyphs. * src/autofit/hbshim.c, src/autofit/hbshim.h: Replaced by... * src/autofit/afshaper.c, src/autofit/afshaper.h: ... these two new files, providing a new API to access HarfBuzz. The new API manages a HarfBuzz buffer with `af_shaper_buf_create' and `af_shaper_buf_destroy'. The buffer receives a UTF8 encoded string with function `af_shaper_get_cluster', and the resulting glyph data (indices, advance widths, vertical offsets) can be iteratively accessed with function `af_shaper_get_elem'. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits): Updated. * include/freetype/internal/fttrace.h: s/afharfbuzz/afshaper/. * src/autofit/afglobal.c: s/hbshim.h/afshaper.h/. (af_face_globals_compute_style_coverage): Updated. * src/autofit/afglocal.h: s/hbshim.h/afshaper.h/. * src/autofit/autofit.c: s/hbshim.c/afshaper.c/. * src/autofit/Jamfile, src/autofit/rules.mk (AUTOF_DRV_SRC): Updated.

Werner Lemberg 072dc45d 2013-12-28T12:26:21 [autofit] Code shuffling to reduce use of cpp macros. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Call `af_get_coverage' unconditionally. * src/autofit/autofit.c: Include `hbshim.c' unconditionally. * src/autofit/hbshim.c (af_get_coverage) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Provide dummy function. * src/autofit/hbshim.h: Provide function declarations unconditionally.
Werner Lemberg 19241347 2013-12-21T21:31:38 Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros. (AF_Coverage): New enumeration (generated by `afcover.h'). (AF_StyleClassRec): New member `coverage'. (AF_DEFINE_STYLE_CLASS): Updated. * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage data. * src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros. (AF_SCRIPT_FALLBACK): Renamed to ... (AF_STYLE_FALLBACK): ... this. * src/autofit/afglobal.c: Include `hbshim.c'. Update use of `SCRIPT' and `STYLE' macros. (af_face_globals_compute_style_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style. (af_property_get, af_autofitter_init): Updated. * src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros. * src/autofit/afranges.h: Update use of `SCRIPT' macro. * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include `hbshim.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'. (AUTOF_DRV_H): Add `afcover.h'. * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Use pkg-config for all libraries needed by FreeType.
Werner Lemberg d8324571 2013-12-19T15:45:24 [autofit] Factor scripts and uniranges out of writing system files. * src/autofit/afranges.c, src/autofit/afranges.h: New files. * src/autofit/afscript.h: Extend `SCRIPT' macro with more parameters, taking data from the writing system files. * src/autofit/aftypes.h: Updated. * src/autofit/afglobal.c: Include `afranges.h'. Load `afscript.h' to call AF_DEFINE_SCRIPT_CLASS. * src/autofit/afglobal.c: Include `afranges.h'. Load `afscript.h' to call AF_DECLARE_SCRIPT_CLASS. * src/autofit/afcjk.c, src/autofit/afcjk.h: Updated. * src/autofit/afdummy.c, src/autofit/afdummy.h: Updated. * src/autofit/afindic.c, src/autofit/afindic.h: Updated. * src/autofit/aflatin.c, src/autofit/aflatin.h: Updated. * src/autofit/aflatn2.c, src/autofit/aflatn2.h: Updated. * src/autofit/afpic.c: Updated. * src/autofir/autofit.c: Include `afranges.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `afranges.c'.
Werner Lemberg db3e5b93 2013-08-25T08:23:22 [autofit] Add blue stringsets. * src/autofit/aftypes.h: Include `afblue.h'. (AF_ScriptClassRec): Add `blue_stringset' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/autofit.c: Include `afblue.c'. * src/autofit/afcjk.c (af_hani_script_class), src/autofit/afdummy.c (af_dflt_script_class), src/autofit/afindic.c (af_deva_script_class), src/autofit/aflatin.c (af_latn_script_class), src/autofit/aflatin2.c (af_ltn2_script_class): Updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `afblue.c'.

Wu, Chia-I (吳佳一) 4cdb45c0 2006-02-09T14:17:04 Introduce experimental autofit CJK module based on akito's autohint patch.

David Turner 9bfbf79c 2004-02-23T21:08:37 adding support for dummy script, i.e. no-hinting for non latin glyphs
Werner Lemberg 6b3d00e1 2004-02-03T21:34:29 * src/type1/t1load.c (parse_dict): Handle `RD' and `-|' commands outside of /Subrs or /CharStrings. This can happen if there is additional code manipulating those two arrays so that FreeType doesn't recognize them properly. (T1_Open_Face): Improve an error message. Remove CR/LF on many files.
David Turner f546bacd 2004-02-01T16:59:06 * src/sfnt/Jamfile: removing "ttcmap" from the list of sources * src/cache/*, include/freetype/cache/*: fixing a bug after heavy testing. The current sources are now "release candidates" for the final version of the cache sub-system * Jamfile: updating "refdoc" target, and adding "autohint" to the list of modules to build. Both the autohinter and autofitter will be built by default. But which one will be used is determined by the content of "ftmodule.h" * src/autofit/*: much updates, but the code is still buggy as hell. Aargh..
