Werner Lemberg dd305f31 2015-12-09T21:00:33 [autofit] Thinko. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Don't count empty blue zones (bug introduced 2015-12-06).
Werner Lemberg 0164d934 2015-12-09T20:04:18 [autofit] Introduce subscript top blue zones. This feature is mainly for Khmer: The idea is to avoid a clash between the top of subscript glyphs and the bottom of normal baseline glyphs. This only works for character clusters mapped to multiple glyphs. * src/autofit/afblue.dat: Add subscript top blue zone for Khmer. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_SUB_TOP): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.h (AF_LATIN_IS_SUB_TOP_BLUE, AF_LATIN_BLUE_SUB_TOP): New macros. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle new blue zone property.

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.
Werner Lemberg a8a54c30 2015-12-05T13:26:44 * src/autofit/afblue.dat: Separate blue zone characters with spaces. Another preparation for character cluster support. * src/autofit/afblue.c, src/autofit.afblue.h: Regenerated.
Werner Lemberg 453722db 2015-12-05T13:20:30 * src/tools/afblue.pl (convert_ascii_chars): Don't ignore spaces. Instead, reduce multiple spaces to a single one. We need this later for supporting character clusters in `afblue.dat'.
Werner Lemberg f7e6d51a 2015-12-05T13:08:45 * src/autofit/afblue.hin (GET_UTF8_CHAR): Use `do...while(0)'. * src/autofit/afblue.h: Regenerated.
Werner Lemberg 53696f03 2015-12-05T07:44:16 * src/autofit/afwarp.c: s/INT_MIN/FT_INT_MIN/.
Werner Lemberg a4154738 2015-12-03T07:49:46 * builds/unix/install.mk (install): Remove stale `ft2build.h'.

Werner Lemberg 6bda921d 2015-11-02T06:53:48 [ftfuzzer] Update README file.
Werner Lemberg bcf618b2 2015-11-02T06:50:49 [ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way.

Werner Lemberg 6a19a7d3 2015-10-26T15:40:22 [truetype] Fix sanitizing logic for `loca' (#46223). * src/truetype/ttpload.c (tt_face_load_loca): A thinko caused an incorrect adjustment of the number of glyphs, most often using far too large values.
Werner Lemberg 7f00fa64 2015-10-25T10:59:59 [autofit] Improve tracing. * src/autofit/afhints.c (af_print_idx, af_get_segment_index, af_get_edge_index): New functions. (af_glyph_hints_dump_points): Remove unnecessary `|', `[', and `]'. Add segment and edge index for each point. Slightly change printing order of some elements. Don't print `-1' but `--' for missing elements. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Remove unnecessary `|', `[', and `]'. Don't print `-1' but `--' for missing elements.

Werner Lemberg 6f09011f 2015-10-24T10:10:22 [sfnt] Sanitize bitmap strike glyph height. Problem reported by Nikolay Sivov <bunglehead@gmail.com>. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Avoid zero value for `metrics->height' by applying some heuristics.
Werner Lemberg e93d326c 2015-10-22T10:17:20 [sfnt, type42] Fix clang compiler warnings. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `offset'. * src/type42/t42parse.c (t42_parse_sfnts): Use proper cast.
Werner Lemberg f1c93439 2015-10-22T10:11:23 [cff] Avoid overflow/module arithmetic. This modifies the addition of subroutine number to subroutine bias from unsigned to signed, but does not change any results. * src/cff/cf2ft.c (cf2_initGlobalRegionBuffer, cf2_initLocalRegionBuffer): Change variable names from (unsigned) `idx' to (signed) `subrNum', since it is not an index until after the bias is added. * src/cff/cf2ft.h: Updated. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Updated similarly.
Werner Lemberg 59ae73fe 2015-10-22T09:26:00 [cid] Better check of `SubrCount' dictionary entry (#46272). * src/cid/cidload.c (cid_face_open): Add more sanity tests for `fd_bytes', `gd_bytes', `sd_bytes', and `num_subrs'.
