Werner Lemberg 75722f89 2015-11-11T09:55:16 [cff, autofit] Switch off stem darkening by default. * src/autofit/afmodule.c (af_autofitter_init), src/cff/cffobjs.c (cff_driver_init): Do it.
Philipp Knechtges be32b168 2015-11-08T08:37:51 [autofit] Don't distort (latin) glyphs too much (#46195). * src/autofit/aflatin.h (AF_LatinBlueRec): Add `ascender' and `descender' fields. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Collect ascender and descender data for blue zones. (af_latin_metrics_scale_dim): Reject vertical scaling values that change the result by more than two pixels.
Nikolaus Waxweiler b6fd5bc0 2015-11-03T10:40:58 * src/autofit/afloader.c (af_loader_load_g): Implement emboldening.
Nikolaus Waxweiler bf2ba9e3 2015-11-02T13:12:34 [autofit] Implement darkening computation function. This is a crude adaption of the original `cf2_computeDarkening' function. * src/autofit/afloader.c (af_intToFixed, af_fixedToInt, af_floatToFixed): New macros, taken from `cf2fixed.h'. (af_loader_compute_darkening): New function. * src/autofit/afloader.h: 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.

Alexei Podtelezhnikov a9f6f04e 2015-09-04T22:28:13 [autofit] Missing piece.
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.

Werner Lemberg 696b7126 2015-09-04T10:10:59 [autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.

Werner Lemberg 40103a3a 2015-08-31T08:51:52 [autofit] Code clean-up. * src/autofit/afglobal.h (AF_STYLE_MASK): New macro. (AF_STYLE_UNASSIGNED): Use AF_STYLE_MASK for definition. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): Updated.
Werner Lemberg 87c81f04 2015-08-30T10:35:21 [autofit] Make glyph style array use 16bit values. * include/freetype/ftautoh.h (FT_Prop_GlyphToScriptMap): Use `FT_UShort' for `map' field. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage, af_face_globals_new), src/autofit/hbshim.c, src/autofit/hbshim.h (af_get_coverage): Use FT_UShort for `glyph_styles' array. * src/autofit/afglobal.h (AF_STYLE_UNASSIGNED, AF_DIGIT): Extend to 16 bits. (AF_FaceGlobalsRec): Use `FT_UShort' for `glyph_styles' field.
Werner Lemberg ff406e2e 2015-08-06T07:34:50 [autofit] Improve Arabic hinting. Problem reported by Titus Nemeth <tn@tntypography.eu> (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
Werner Lemberg 15e2a4f7 2015-08-05T21:53:50 [autofit] Improve recognition of flat vs. rounded segments. Lower the flatness threshold from upem/8 to upem/14, making the auto-hinter accept shorter elements. Synchronize flat/round stem selection algorithm with blue zone code. * src/autofit/aflatin.c (FLAT_THRESHOLD): New macro. (af_latin_metrics_init_blues): Use it. (af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'.
Werner Lemberg f9be567f 2015-07-09T15:10:31 Better support of user-supplied C++ namespaces.

Werner Lemberg 31d97df9 2015-06-21T19:12:12 Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.

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 b6cb4997 2015-02-06T08:46:06 [autofit] Fix potential memory leak. While this doesn't show up with FreeType, exactly the same code leaks with ttfautohint's modified auto-hinter code (which gets used in a slightly different way). It certainly doesn't harm since it is similar to already existing checks in the code for embedded arrays. * src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours' and `max_points' for all cases.
Werner Lemberg 19146a53 2015-01-31T11:01:33 [autofit] Add support for Thai script.

Behdad Esfahbod 48c86628 2015-01-14T19:38:36 * src/autofit/afmodule.c (af_autofitter_done): Fix compiler warning.
Behdad Esfahbod 56ddafa0 2015-01-14T19:36:02 [autofit] Add embedded array of segments and edges. Avoids multiple mallocs per typical glyphs. With this and recent changes to avoid mallocs, the thread-safe stack-based loader is now as fast as the previous model that had one cached singleton. * src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED): New macros. (AF_AxisHintsRec): Add two arrays for segments and edges. * src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate data if number of segments exceeds given threshold value. (af_axis_hints_new_edge): Only allocate data if number of edges exceeds given threshold value. (af_glyph_hints_done): Updated.
Behdad Esfahbod 6f16b100 2015-01-14T19:26:49 [autofit] Add embedded arrays for points and contours. This avoids at least two malloc calls for typical glyphs. * src/autofit/afhints.h (AF_POINTS_EMBEDDED, AF_CONTOURS_EMBEDDED): New macros. (AF_GlyphHintsRec): Add two arrays for contours and points. * src/autofit/afhints.c (af_glyph_hints_init, af_glyph_hints_done): Updated. (af_glyph_hints_reload): Only allocate data if number of contours or points exceeds given threshold values.
Behdad Esfahbod c2733656 2015-01-14T19:16:12 [autofit] Allocate hints object on the stack. This avoids one malloc per load. * src/autofit/afloader.h (AF_LoaderRec): Change type of `hints' to `AF_GlyphHints'. Update prototype. * src/autofit/afloader.c (af_loader_init): Use `AF_GlyphHints' parameter instead of `FT_Memory'. (af_loader_done): Directly reset `load_hints'. (af_loader_load_g): Updated. * src/autofit/afmodule.c (af_autofitter_load_glyph): Use local `hints' object.
Behdad Esfahbod a4117fbd 2015-01-14T19:07:54 [autofit] Reuse slot glyph loader. No need to create a new glyph loader; we can reuse the one from `slot->internal->loader'. It's hard to tell why it was written that way originally, but new code looks sound and correct to me, and avoids lots of allocations. * src/autofit/afloader.c (af_loader_init): Change return type to `void'. Don't call `FT_GlyphLoader_New'. (af_loader_reset): Don't call `FT_GlyphLoader_Rewind'. (af_loader_load_g): Update code to use `internal->loader', which doesn't need copying of data. * src/autofit/afloader.h (AF_LoaderRec): Remove `gloader' member. Update prototype. * src/autofit/afmodule.c (af_autofitter_load_glyph): Updated.
Behdad Esfahbod ae6699f8 2015-01-14T18:55:39 [autofit] Remove (unused) support for composite glyphs. We never have to deal with composite glyphs in the autohinter, as those will be loaded into FORMAT_OUTLINE by the recursed `FT_Load_Glyph' function. In the rare cases that FT_LOAD_NO_RECURSE is set, it will imply FT_LOAD_NO_SCALE as per `FT_Load_Glyph', which then implies FT_LOAD_NO_HINTING: /* resolve load flags dependencies */ if ( load_flags & FT_LOAD_NO_RECURSE ) load_flags |= FT_LOAD_NO_SCALE | FT_LOAD_IGNORE_TRANSFORM; if ( load_flags & FT_LOAD_NO_SCALE ) { load_flags |= FT_LOAD_NO_HINTING | FT_LOAD_NO_BITMAP; load_flags &= ~FT_LOAD_RENDER; } and as such the auto-hinter is never called. Thus, the recursion in `af_loader_load_g' never actually happens. So remove the depth counter as well. * src/autofit/afloader.c (af_loader_load_g): Remove `depth' parameter. <FT_GLYPH_FORMAT_COMPOSITE>: Remove associated code. (af_loader_load_glyph): Updated.
Behdad Esfahbod 89bc8d4d 2015-01-14T16:01:19 [autofit] Allocate AF_Loader on the stack instead of AF_Module. Stop sharing a global `AF_Loader'. Allocate one on the stack during glyph load. Right now this results in about 25% slowdown, to be fixed in a following commit. With this patch loading glyphs from different faces from different threads doesn't immediately crash in the autohinting loader code. Bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1164941 * src/autofit/afloader.c (af_loader_init): Pass `AF_Loader' and `FT_Memory' instead of `AF_Module' as arguments. (af_loader_reset, af_loader_load_glyph): Also pass `loader' as argument. (af_loader_done): Use `AF_Loader' instead of `AF_Module' as argument. * src/autofit/afmodule.c (af_autofitter_init): Don't call `af_loader_init'. (af_autofitter_done): Don't call `af_loader_done'. (af_autofitter_load_glyph): Use a local `AF_Loader' object. * src/autofit/afloader.h: Include `afmodule.h'. Update prototypes. Move typedef for `AF_Module' to... * src/autofit/afmodule.h: ... this place. No longer include `afloader.h'.
Werner Lemberg 36d03c9f 2015-01-12T11:26:30 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.

Werner Lemberg a632b5f4 2014-12-03T19:30:44 [autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
suzuki toshiya 9ee6a0a0 2014-11-28T11:14:18 Fix compiler warning to conversion specifiers in debug messages. * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length modifier to dump long integers. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.

Werner Lemberg 63bef9a5 2014-05-01T07:16:05 [autofit] Fix handling of neutral blue zones in stems. * src/autofit/afhints.h (AF_Edge_Flags): New value `AF_EDGE_NEUTRAL'. * src/autofit/aflatin.c (af_latin_hints_compute_blue_edges): Trace neutral blue zones with AF_EDGE_NEUTRAL. (af_latin_hint_edges): Skip neutral blue zones if necessary.
Werner Lemberg ccfc4b4c 2014-04-28T21:13:14 [autofit] Introduce neutral blue zones to the latin module. Such blue zones match either the top or the bottom of a contour. We need them for scripts where accent-like elements directly touch the base character (for example, some vowel signs in Devanagari, cf. U+0913 or U+0914). * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_NEUTRAL): New property. * src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.h (AF_LATIN_IS_NEUTRAL_BLUE): New macro.

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 8c7fb78b 2014-04-17T15:53:25 [autofit] More coverage fixes for complex scripts. * src/autofit/hbshim.c (af_get_coverage): Merge input glyph coverage of GSUB lookups into output coverage. Otherwise, ligatures are not handled properly. Don't check blue zone characters for default coverage.
Werner Lemberg 8b1f2a6c 2014-04-14T07:58:19 [autofit] Improve coverage handling. * src/autofit/hbshim.c (af_get_coverage): Don't exclude glyphs appearing in the GPOS table if we are processing the default coverage.
Werner Lemberg 8a94b1ef 2014-04-12T20:44:33 [autofit] Redesign the recognition algorithm of strong points. In particular, local extrema without horizontal or vertical segments are better recognized: + A + D \ / \ / \ / \ / \ + C \ / B +/ If the distances AB and CD are large, point B wasn't previously detected as an extremum since the `ft_corner_is_flat' function `swallowed' BC regardless of its direction, tagging point B as weak. The next iteration started at B and made `ft_corner_is_flat' swallow point C, tagging it as weak also, et voilà. To improve that, another pass gets now performed before calling `ft_corner_is_flat' to improve the `topology' of an outline: A sequence of non-horizontal or non-vertical vectors that point into the same quadrant are handled as a single, large vector. Additionally, distances of near points are now accumulated, which makes the auto-hinter handle them as if they were prepended to the next non-near vector. This generally improves the auto-hinter's rendering results. * src/autofit/afhints.c (af_glyph_hints_reload): Implement it. * src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag `AF_FLAG_NEAR'.
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.
