Werner Lemberg 2e09812c 2015-12-25T08:05:30 [autofit] Make top-to-bottom hinting work in latin auto-hinter. This improves rendering of scripts like Bengali or Devanagari. * src/autofit/afhints.c (af_axis_hints_new_edge): Add parameter to pass top-to-bottom hinting flag. This makes the function sort edges in descending vertical position. * src/autofit/afhints.c: Updated. * src/autofit/aflatin.c (af_latin_hints_compute_edges, af_latin_hint_edges): Use `top_to_bottom_hinting' flag. * src/autofit/afcjk.c (af_cjk_hints_compute_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_edges): Updated.
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 37c401ac 2015-11-02T09:32:26 [autofit] Add functions to get standard widths for writing systems. We need the computed standard horizontal and vertical widths for the emboldening calculation. This method provides a convenient way to extract it from writing-system-specific metrics structures, which all script definitions must implement. * src/autofit/aftypes.h (AF_WritingSystem_GetStdWidthsFunc): New function type. (AF_WritingSystemClassRec): New member `style_metrics_getstdw'. (AF_DEFINE_WRITING_SYSTEM_CLASS): Updated. * src/autofit/afcjk.c (af_cjk_get_standard_width): New function.

Werner Lemberg 8cbbcf6b 2015-09-03T06:47:30 [autofit] Pass glyph index to hinting function. No functionality change yet. * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Pass glyph index. * src/autofit/afcjk.c, src/autofit/afcjk.h (af_cjk_hints_apply), src/autofit/afdummy.c (af_dummy_hints_apply), src/autofit/afindic.c (af_indic_hints_apply), src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/aflatin2.c (af_latin2_hints_apply), src/autofit/afloader.c (af_loader_load_g): Updated.
Werner Lemberg 12661a5a 2015-04-21T07:13:59 [autofit] Introduce `warping' property. This code replaces the debugging hook from the previous commit with a better, more generic solution. * include/ftautoh.h: Document it. * src/autofit/afmodule.h (AF_ModuleRec) [AF_CONFIG_OPTION_USE_WARPER]: Add `warping' field. * src/autofit/afmodule.c (_af_debug_disable_warper): Remove. (af_property_set, af_property_get, af_autofitter_init) [AF_CONFIG_OPTION_USE_WARPER]: Handle `warping' option. * src/autofit/afhints.h (AF_HINTS_DO_WARP): Remove use of the no longer existing `_af_debug_disable_warper'. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2.c (af_latin2_hints_init) [AF_CONFIG_OPTION_USE_WARPER]: Add `AF_SCALER_FLAG_NO_WARPER' to the scaler flags if warping is off. * src/autofit/aftypes.h: Updated.
Werner Lemberg 58f48f0d 2015-04-16T20:11:49 [autofit] Add debugging hook to disable warper. * src/autofit/afmodule.c (_af_debug_disable_warper) [FT_DEBUG_AUTOFIT]: New global variable. * src/autofit/aftypes.h: Updated. (AF_SCALER_FLAG_NO_WARPER): New macro (not actively used yet). * src/autofit/afhints.h (AF_HINTS_DO_WARP): New macro. * src/autofi/aflatin.c (af_latin_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Use `AF_HINTS_DO_WARP' to control use of warper. * src/autofit/afcjk.c (af_cjk_hints_init, af_cjk_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'. * src/autofit/aflatin2.c (af_latin2_hints_apply) [AF_CONFIG_OPTION_USE_WARPER]: Synchronize with `aflatin.c'.

Werner Lemberg 81e5ff53 2015-02-19T09:46:48 [autofit] Use macros for (unsigned) flags, not enumerations. This harmonizes with other code in FreeType (and reduces the number of necessary casts to avoid compiler warnings). * src/autofit/afblue.hin: Make flag macros unsigned. * src/autofit/afblue.h: Regenerated. * src/autofit/afcjk.h: Replace flag enumeration with macros. * src/autofit/afcjk.c: Updated. * src/autofit/afhints.h (AF_Flags, AF_Edge_Flags): Replace with macros. * src/autofit/afhints.c: Updated. * src/autofit/aflatin.h: Replace flag enumerations with macros. * src/autofit/aflatin.c, src/autofit/aflatin2.c: Updated. * src/autofit/aftypes.h (AF_ScalerFlags): Replace with macros.

Werner Lemberg 378266dc 2014-09-22T06:33:38 Formatting.
Werner Lemberg 98e510ee 2014-04-20T22:11:27 [autofit] Fix Savannah bug #42148. The adaptation of the cjk auto-hinter module to blue stringsets in 2013-08-25 had three severe bugs. Mea culpa. 1. Contrary to the latin auto-hinter, characters for reference and overshoot values of a blue zone are specified separately. Due to the screwed-up change it didn't work at all. 2. A boolean comparison was erroneously replaced with a cast, causing invalid results with the `^' operator later on. The visual artifact caused by this problem is the topic of the bug report. 3. Two flag values were inverted, causing incorrect assignment of reference and overshoot values. * src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new syntax to have both reference and overshoot characters in a single string. This is error #1. Add extensive comments. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no longer used. (AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values. This is error #3. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1. Use character `|' to separate characters for reference and overshoot values. Improve tracing messages, synchronizing them with the latin auto-hinter. (af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'. This is error #2. (af_cjk_align_linked_edge): Add tracing message. * src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer used.
Werner Lemberg 71f53e12 2014-04-05T16:27:19 [autofit] Improve scoring algorithm for identifying stems. Problem reported by Karsten Lücke <karsten.luecke@kltf.de>. The new algorithm takes care of the width of stems: If the distance between two segments is larger than the largest stem width, the demerits quickly increase for larger distances. This improves hinting of slanted fonts (especially if the inner parts of serifs have non-horizontal `shoulders'), avoiding false stem links. * src/autofit/aflatin.c (af_latin_hints_link_segments): Use largest stem width (if available) to compute better demerits for distances between stems. (af_latin_hints_detect_features): Pass stem width array and array size. (af_latin_metrics_init_widths): Updated to use original algorithm. (af_latin_hints_apply): Updated to use new algorithm. * src/autofit/aflatin.h: Updated. * src/autofit/afcjk.c: Updated.

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. (AF_ScriptClassRec): Add members to hold two more standard characters. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afglobal.c, src/autofit/afglobal.h, * src/autofit/afpic.c, src/autofit/afranges.h, src/autofit/hbshim.c: Update use of `SCRIPT' macro. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Scan two more standard characters.
