cda418a4 2025-06-13 11:23:14 [autofit] Speed up computation of `af_reverse_character_map_new`. (1/4) Using HarfBuzz's API functions to construct the reverse map is too slow; we have to call `hb_ot_layout_lookup_get_glyph_alternates` far too often because it can only handle a single glyph at a time. For this reason we are going to parse the GSUB table by ourselves. The new non-local functions are `af_parse_gsub` and `af_map_lookup`. * src/autofit/afgsub.c, src/autofit/afgsub.h: New files for parsing, validating, and mapping the `SingleSubst` and `AlternateSubst` subtable types of a GSUB table. * src/autofit/autofit.c, src/autofit/rules.mk (AUTOF_DRV_SRC): Updated.
3eb4eade 2025-04-12 00:44:46 [autofit] Rename 'ft-hb' to 'ft-hb-ft'. Since it's a (shrinked) copy of 'hb-ft'. * src/autofit/afglobal.c (af_face_globals_new), src/autofit/afshaper.h, src/autofit/autofit.c: Updated. * src/autofit/ft-hb.c, src/autofit/ft-hb.h: Renamed to... * src/autofit/ft-hb-ft.c, src/autofit/ft-hb-ft.h: ...this; updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Updated.
7651fe00 2025-04-27 18:44:49 [autofit] Enable dynamic loading of HarfBuzz. (1/2) This commit activates the mini-HarfBuzz header files and provides the necessary infrastructure for dynamically loading HarfBuzz if `FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC` is defined (this macro gets set up in a follow-up commit). * src/autofit/ft-hb.c: New file, providing `ft_hb_funcs_init` and `ft_hb_funcs_done` for loading HarfBuzz dynamically. The name of the library is hold in the macro `FT_LIBHARFBUZZ`, which can be overridden. * src/autofit/ft-hb.h: Don't include `hb.h` but `ft-hb-types.h`. (hb): Modified to handle both standard linking and dynamically loading of HarfBuzz. (HB_EXTERN): New macro to load `ft-hb-decls.h`. * src/autofit/afadjust.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: For the sake of dynamically loading the HarfBuzz library, replace the compile-time macro `HB_VERSION_ATLEAST` with a call to the run-time function `hb_version_atleast` where necessary – a follow-up commit will set the minimum version of HarfBuzz to 2.6.8, which provides all necessary functions needed by FreeType. * src/autofit/afmodule.h: Include `ft-hb.h`. (AF_ModuleRec) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Add `hb_funcs` structure to hold pointers to the dynamically loaded HarfBuzz functions. * src/autofit/afmodule.c (af_autofitter_init, af_autofitter_done) [FT_CONFIG_OPTION_USE_HARFBUZZ_DYNAMIC]: Call `ft_hb_funcs_init` and `ft_hb_funcs_done`. * src/autofit/afshaper.h: Updated. * src/autofit/autofit.c: Include `ft-hb.c`. * src/autofit/rules.mk (AUTOF_DRV_SRC, AUTOF_DRV_H): Updated.
c46ebd76 2024-01-28 17:27:39 [autofit] Add adjustment database. * src/autofit/afadjust.c, src/autofit/afadjust.h: New files. * include/freetype/internal/fttrace.h: Add 'afadjust' component. * src/autofit/autofit.c: Include `afadjust.c`. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `afadjust.c`.

995ccfac 2023-02-08 21:49:56 [autofit] Fix 'multi' compilation. * src/autofit/ft-hb.c: Decorate with `FT_LOCAL_DEF`. Add ANSI boilerplate code for otherwise empty file. * src/autofit/ft-hb.h: Include `compiler-macros.h` and `freetype.h`. Use `FT_BEGIN_HEADER` and `FT_END_HEADER`. Decorate with `FT_LOCAL`. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `ft-hb.c`.

5bcaf51b 2021-07-23 11:59:58 [autofit] Split `afwrtsys.h`. The header file `afwrtsys.h` has two distinct functions: to include the required writing system headers and also to generate code for each writing system. At each current use site only one or the other is used, with various macro trickery selecting one or the other. Split this header into `afws-decl.h` for the required writing system declarations and `afws-iter.h` for iterating over the writing systems to generate code. The motivation for this change is that the Visual C++ compiler treats the standard include guard idiom like `#pragma once` 'if no non-comment code or preprocessor directive comes before or after the standard form of the idiom'. It appears to check this after macro expansion, so if `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and looks like the standard include guard idiom which is treated like `#pragma once`, so subsequent inclusion of `afwrtsys.h` is elided. Fixes #1075. * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated. * src/autofit/afwrtsys.h: Split into... * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.
a212668c 2021-06-02 19:07:56 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.
2f11522a 2021-06-02 19:05:09 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.

24aa9c66 2015-12-06 18:52:41 [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.
f57fc59e 2015-01-17 20:41:43 Run `src/tools/update-copyright'.
36d03c9f 2015-01-12 11:26:30 Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src/*/rules.mk (*_COMPILE): Fix order of include directories.
19241347 2013-12-21 21:31:38 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.
974b193b 2013-12-20 17:26:26 [autofit] Introduce `styles'. This is the new top-level structure for handling glyph input data; scripts are now defined separately. * src/autofit/aftypes.h (SCRIPT): Updated. (AF_ScriptClassRec): Move `blue_stringset' and `writing_system' members to ... (AF_Style_ClassRec): ... this new structure. (AF_Style): New enumeration. (AF_StyleMetricsRec): Replace `script' enumeration with `style_class' pointer. (AF_DEFINE_SCRIPT_CLASS, AF_DECLARE_SCRIPT_CLASS): Updated. (AF_DEFINE_STYLE_CLASS, AF_DECLARE_STYLE_CLASS): New macros. * src/autofit/afstyles.h: New file, using data from `afscript.h'. * src/autofit/afscript.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_hint_edges): Updated. * src/autofit/afglobal.c (SCRIPT): Updated. (STYLE): Redefine macro to load `afstyles.h'. (af_script_names) [FT_DEBUG_LEVEL_TRACE]: Replace with... (af_style_names): ... this array. (af_face_globals_compute_script_coverage): Renamed to... (af_face_globals_compute_style_coverage): ... this. Updated. (af_face_globals_new, af_face_globals_free, af_face_globals_get_metrics): Updated. * src/autofit/afglobal.h (SCRIPT): Updated. (STYLE): Redefine macro to load `afstyles.h'. (AF_SCRIPT_FALLBACK): Update definition. This will get more refinements with later on. (AF_SCRIPT_UNASSIGNED): Replace with...

456cc440 2013-08-02 20:25:21 [autofit] Move declaration of scripts into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afscript.h: New file. * src/autofit/aftypes.h (AF_Script): Include `afscript.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afscript.h' to get the script specific header files. (af_script_classes): Include `afscript.h' to fill this array. * src/autofit/afpic.c: Include `afscript.h' to get the script specific header files. (autofit_module_class_pic_init): Include `afscript.h' for initialization. * src/autofit/afpic.h (AF_SCRIPT_CLASSES_COUNT, AF_SCRIPT_CLASSES_REC_COUNT): Removed.
