Werner Lemberg ec776596 2016-01-19T19:33:57 [autofit] Fix handling of default script. Patch taken from ttfautohint, commit 071ae2c00e0d67f9d19418f4fade1c23d27dc185. There were two bugs. - We now use non-standard script tags like `khms' for special purposes. However, HarfBuzz maps such tags to `DFLT', and without this commit the associated lookups were incorrectly assigned to the non-standard tags. - Let's assume we have a Bengali font, and the font's `DFLT' script tag handles the necessary lookups for Bengali, too. Without this commit, the `DFLT' lookups were assigned to ttfautohint's default script (usually `latn') before the standard lookups for Bengali were handled. We now have the following order while searching for covered glyph indices. special features of scripts (e.g. `sups' for Cyrillic) Unicode mappings of scripts remaining features of scripts (especially important for Indic scripts) default features of default script * src/autofit/afshaper.c, src/autofit/afshaper.h (af_shaper_get_coverage): Add boolean parameter to indicate default script. Update all callers. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Fix search order for coverages.
Werner Lemberg 9adeab64 2016-01-13T11:54:10 Update copyright year.
Werner Lemberg 172db325 2015-12-24T08:17:51 [autofit] Add hinting direction to `AF_ScriptClassRec'. Still unused. * src/autofit/afglobal.c (SCRIPT): Handle hinting direction. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `top_to_bottom_hinting' field. (AF_HINTING_BOTTOM_TO_TOP, AF_HINTING_TOP_TO_BOTTOM): New macros. (AF_DEFINE_SCRIPT_CLASS): Updated.
Werner Lemberg b0de5a82 2015-12-23T23:25:03 [autofit] Start implementing hinting direction (up/down, down/up). Right now, it does nothing. * src/autofit/afscript.h: Add another parameter to `SCRIPT', specifying hinting direction. * src/autofit/afglobal.c, scr/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/afshaper.c, src/autofit/aftypes.h: Extend `SCRIPT' definitions.
Werner Lemberg 4fe3b55d 2015-12-11T08:08:48 [autofit] Restore OpenType feature check. This was removed while rewriting the HarfBuzz interface. * src/autofit/afglobal.h (AF_FaceGlobalsRec): Add `hb_buf' field to hold internal HarfBuzz buffer, needed for feature comparison. * src/autofit/afglobal.c (af_face_globals_new, af_face_globals_free): Initialize and destroy `hb_buf'. * src/autofit/afshaper.c (af_shaper_get_cluster): Compare character (cluster) with and without applied feature. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix tracing message.
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 f45c0bf9 2015-12-06T09:58:18 [autofit] Use string of standard characters. This is more flexible; additionally, it would allow character clusters. * src/autofit/aftypes.h (SCRIPT, AF_DEFINE_SCRIPT_CLASS): Updated. (AF_ScriptClassRec): Replace `standard_char[123]' with `standard_charstring'. * src/autofit/afscript.h: Replace last three character arguments of the `SCRIPT' calls with a string parameter, holding the standard characters (in UTF-8 encoding) separated with spaces. * src/autofit/afglobal.c, src/autofit/afglobal.h, src/autofit/afpic.c, src/autofit/afranges.c, src/autofit/hbshim.c (SCRIPT): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Updated.
Nikolaus Waxweiler b2a85ad3 2015-11-02T09:20:32 [autofit] Extend `AF_FaceGlobalsRec' to hold emboldening data. * src/autofit/afglobal.h (AF_FaceGlobalsRec): Add fields. * src/autofit/afglobal.c (af_face_globals_new): Initialize new fields. (af_face_globals_free): Reset new fields.
Werner Lemberg dbd04269 2015-09-30T17:52:42 [autofit] Replace `no-base' with `non-base'. * src/autofit/*: Do it.
Werner Lemberg d3cba0ed 2015-09-04T10:28:53 [autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters. (AF_STYLE_MASK): Updated. * src/autofit/afglobal.c (SCRIPT): Updated. (af_face_globals_compute_style_coverage): Handle new style flag. * src/autofit/aflatin.c (af_latin_hints_apply): Handle new style flag. * src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.

(AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
Werner Lemberg b57bb11a 2015-02-19T10:44:18 [autofit] Fix signedness issues. * src/autofit/afangles.c, src/autofit/afcjk.c, src/autofit/afglobal.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/autofit/aflatin2.c, src/autofit/afwarp.c, src/autofit/hbshim.c: Apply.

Werner Lemberg a3364001 2014-01-26T09:45:23 [autofit] Introduce two more slots for standard characters. This is useful for OpenType features like `c2sc' (caps to small caps) that don't have lowercase letters by definition, or other features that mainly operate on numerals. * src/autofit/afscript.h: Add more standard characters. * src/autofit/aftypes.h: Update use of `SCRIPT' macro.

Werner Lemberg c7b55a34 2013-12-23T16:42:03 Split off ChangeLog.24.
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.

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'.

Werner Lemberg 89a529f3 2013-08-02T14:50:23 [autofit] Fix `make multi'. * include/freetype/config/ftconfig.h (FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF): New macros. * src/autofit/afglobal.c (af_writing_system_classes, af_script_classes): Use FT_LOCAL_ARRAY_DEF. * src/autofit/afglobal.h: Declare `af_writing_system_classes' and `af_script_classes'. * src/autofit/afloader.c: Include `afpic.h'.
Werner Lemberg 72f5ff5b 2013-07-31T22:49:29 [autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure. It holds pointers to functions which can be shared among related scripts. (AF_WritingSystem): New enumeration. (AF_Script): Revised values using four-letter tags. (AF_DEFINE_WRITING_SYSTEM_CLASS): New macro. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afglobal.c (af_writing_system_classes): New global, constant array. (af_script_classes): Updated. (af_face_globals_free): Updated. Remove assertion. (af_face_globals_get_metrics): Updated. * src/autofit/afglobal.h (AF_SCRIPT_FALLBACK) [!AF_CONFIG_OPTION_CJK]: Handle this case. * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph): Updated. * src/autofit/afpic.c (autofit_module_class_pic_init): Updated; initialize structures for both writing systems and scripts. * src/autofit/afpic.h: Updated. (AF_WRITING_SYSTEM_CLASSES_GET): New macro. * src/autofit/afcjk.c (af_cjk_writing_system_class): New writing system. (af_cjk_uniranges): Renamed to... (af_hani_uniranges): This. (af_cjk_script_class): Reduced and renamed to... (af_hani_script_class): This. * src/autofit/afcjk.h: Updated. * src/autofit/afdummy.c (af_dummy_writing_system_class): New writing system. (af_dummy_script_class): Reduced and renamed to... (af_dflt_script_class): This. * src/autofit/afdummy.h: Updated. * src/autofit/afindic.c (af_indic_writing_system_class): New writing system. (af_indic_uniranges): Renamed to... (af_deva_uniranges): This. (af_indic_script_class): Reduced and renamed to... (af_deva_script_class): This. * src/autofit/afcjk.h: Updated. * src/autofit/aflatin.c (af_latin_writing_system_class): New writing system. (af_latin_uniranges): Renamed to... (af_latn_uniranges): This. (af_latin_script_class): Reduced and renamed to... (af_latn_script_class): This. * src/autofit/aflatin.h: Updated. * src/autofit/aflatin2.c (af_latin2_writing_system_class): New writing system. (af_latin2_uniranges): Renamed to... (af_ltn2_uniranges): This. Synchronize ranges with `latin'. (af_latin2_script_class): Reduced and renamed to... (af_ltn2_script_class): This. * src/autofit/aflatin2.h: Updated.
Werner Lemberg 5d6a3605 2013-07-30T23:17:04 [autofit] Variable renaming. * src/autofit/aftypes.h (AF_ScriptMetricsRec): s/clazz/script_class/. Update all users.
Werner Lemberg dc624ca4 2013-06-04T10:30:48 Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results. I will report those issues to the cppcheck team so that a newer version gives improved results hopefully. */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable): Remove unused variable. * src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero. * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate): Remove functionless code. * src/tools/ftrandom.c (main): Fix memory leak.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Werner Lemberg bf745003 2012-09-29T22:40:40 [autofit] Minor optimization. * src/autofit/afglobals.c (af_face_globals_compute_script_coverage): Add loop condition.
Werner Lemberg d180ac70 2012-09-18T23:26:37 [autofit] Implement Infinality's `increase glyph heights'. This is an improved version of a similar fix contained in the so-called `Infinality patch', taken from http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2 which addresses various enhancements of the auto-hinter. Without properties to control a module's metadata it wasn't possible to adapt the patches because everything was originally controlled by environment variables which I consider not suitable in general. A patch to control `increase_x_height' follows. * src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN, AF_PROP_INCREASE_X_HEIGHT_MAX): New macros. (AF_FaceGlobalsRec): Add `increase_x_height' member. * src/autofit/afglobal.c (af_face_globals_new): Initialize it. * src/autofit/aflatin.c (af_latin_metrics_scale_dim), * src/autofit/aflatin2.c (af_latin2_metrics_scale_dim): Implement handling of `increase_x_height'.

Werner Lemberg d0014f2c 2012-09-15T10:33:43 [autofit] Make default script a global property. * src/autofit/afmodule.h (AF_ModuleRec): Add `default_script' field. * src/autofit/afglobal.c (af_face_globals_compute_script_coverage, af_face_globals_new), src/autofit/afloader.c (af_loader_reset), src/autofit/afmodule.c (af_property_get) <glyph-to-script-map>, af_autofitter_init: Handle default script. * src/autofit/afglobal.h: Updated.
Werner Lemberg 7bbbcbfb 2012-09-12T17:45:39 [autofit] Minor reorganization. * src/autofit/afglobal.c (AF_SCRIPT_LIST_DEFAULT, AF_SCRIPT_LIST_NONE, AF_DIGIT): Move to... * src/autofit/afglobal.h (AF_SCRIPT_DEFAULT, AF_SCRIPT_LIST_NONE, AF_DIGIT): This and update code.
Werner Lemberg 2be60cfe 2012-09-01T22:31:43 [autofit] Implement `glyph-to-script-map' property. * include/freetype/ftautoh.h: New public header file. * include/freetype/config/ftheader.h (FT_AUTOHINTER_H): New macro. * src/autofit/afglobal.c (AF_FaceGlobalsRec): Move structure to... * src/autofit/afglobal.h: This header file. * src/autofit/afmodule.c: Include FT_AUTOHINTER_H. (af_property_get): Handle `glyph-to-script-map'.
Werner Lemberg b6978dd0 2012-07-06T19:38:44 [autofit] Do some code cleanup. * src/autofit/afglobal.c (af_face_globals_new): Simplify. * src/autofit/afhints.c: Use `FT_TRACE7' instead of `printf' everywhere. (FT_COMPONENT): New macro. (af_glyph_hints_done): Simplify. * include/freetype/internal/fttrace.h: Updated.

Werner Lemberg 8b84c9d1 2009-04-27T19:40:35 autohinter: Don't change digit widths if all widths are the same. This fixes FreeDesktop bug #21197. * src/autofit/afglobal.c (AF_DIGIT): New macro. (af_face_globals_compute_script_coverage): Mark ASCII digits in `glyph_scripts' array. (af_face_globals_get_metrics): Updated. (af_face_globals_is_digit): New function. * src/autofit/afglobal.h: Updated. (AF_ScriptMetricsRec): Add `digits_have_same_width' flag. * src/autofit/aflatin.c: Include FT_ADVANCES_H.

David Turner e664efad 2004-06-04T17:41:59 * src/autofit/*: important fixes to the auto-fitter. The output now seems to be 100% equivalent to the auto-hinter, while being about 2% faster (which proves that script-specific algorithm selection isn't a performance problem). to test it, change "autohint" to "autofit" in <freetype/config/ftmodule.h> and recompile. a few more testing is needed before making this the official auto-hinting module
