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.
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. (AF_LATIN_BLUE_NEUTRAL): New enumeration value. * src/autofit/aflatin.c (af_latin_metrics_init_blues, af_latin_hints_compute_blue_edges): Handle neutral blue zones.
abb3fcac	2014-04-25T22:13:32	* src/autofit/hbshim.c: Partially revert commit from 2014-04-17. Using input glyph coverage data is simply wrong. Problem reported by Nikolaus Waxweiler <madigens@gmail.com> and Mantas Mikulėnas <grawity@gmail.com>.
426f0e04	2014-04-24T07:13:31	Minor.
f193637f	2014-04-23T08:22:33	* src/raster/ftraster.c (Vertical_Sweep_Span): Use drop-out mode. This spot has been missed while introducing support for various drop-out modes years ago (including no drop-out mode, which this commit fixes). Problem reported by Patrick Thomas <pthomas505@gmail.com>.
d9b4470e	2014-04-22T07:33:07	* src/sfnt/pngshim.c (error_callback): s/longjmp/ft_longjmp/.
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.
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.
bbd8313b	2014-04-17T01:24:36	Make `FT_Get_SubGlyph_Info' actually work. * src/base/ftobjs.c (FT_Get_SubGlyph_Info): Return FT_Err_Ok if there is no error.
181fd071	2014-04-15T16:47:05	[afblue.pl]: Minor improvements. * src/tools/afblue.pl: Allow whitespace before comments. Ignore whitespace in strings.
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.
7630787a	2014-04-13T15:41:13	[smooth] Fix stand-alone compilation. * src/smooth/ftgrays.c (FT_BEGIN_STMNT, FT_END_STMNT): Define.
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'.
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.
87360a78	2014-04-05T00:08:52	[aflatin] Improve comment.
f8555b5d	2014-04-03T05:45:38	Don't require `gzip' module for `sfnt'. Reported by Preet <prismatic.project@gmail.com>. * src/sfnt/sfobjs.c (woff_open_font): Guard use of FT_Gzip_Uncompress with FT_CONFIG_OPTION_USE_ZLIB.
d5159925	2014-03-22T06:20:54	Another revert for the change from 2014-03-18. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>. * src/base/ftcalc.c (FT_MulFix): Ensure that an `FT_MulFix' symbol gets always exported.
cc7cf2c3	2014-03-19T07:35:35	Partially revert last commit. Found by Alexei. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Initializing those variables is plain wrong, since we are in a loop.
87628724	2014-03-18T08:39:35	Fix clang warnings. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Initialize some variables. * src/base/ftcalc.c (FT_MulFix): Only use code if `FT_MULFIX_INLINED' is not defined. * src/bdf/bdfdrivr.c (bdf_cmap_class), src/cache/ftcbasic.c (ftc_basic_image_family_class, ftc_basic_image_cache_class, ftc_basic_sbit_family_class, ftc_basic_sbit_cache_class), src/cache/ftccmap.c (ftc_cmap_cache_class), src/cache/ftcmanag.c (ftc_size_list_class, ftc_face_list_class), src/pcf/pcfdrivr.c (pcf_cmap_class), src/pfr/pfrdrivr.c (pfr_metrics_service_rec): Make function static. * src/type1/t1driver.c (t1_ps_get_font_value): Remove redundant code.
23367ff9	2014-03-17T07:33:14	Fix Savannah bug #41869. This works around a problem with HarfBuzz (<= 0.9.26), which doesn't validate glyph indices returned by `hb_ot_layout_lookup_collect_glyphs'. * src/autofit/hbshim.c (af_get_coverage): Guard `idx'. * docs/CHANGES: Updated.
ed372b71	2014-03-09T06:14:12	Fix cppcheck 1.64 warning. * src/autofit/afglobal.c (af_face_globals_new): Catch NULL pointer dereference in case of error.

05565366	2014-03-06T18:56:58	Fixes for compilation with C++. * src/autofit/hbshim.c (scripts): Change type to `hb_script_t'. (af_get_coverage): Updated. (COVERAGE): Add cast.
b24e8d33	2014-03-06T14:54:22	Remove more clang analyzer warnings. * src/bdf/bdflib.c (_bdf_readstream), src/truetype/ttgload.c (TT_Load_Glyph): Remove dead stores.
7ac76b50	2014-03-04T04:29:17	Fix several clang static analyzer dead store warnings. * src/autofit/afhints.c (af_glyph_hints_reload, af_glyph_hints_align_weak_points): Remove unnecessary assignments. * src/bdf/bdflib.c (bdf_font_load): Ditto. * src/pshinter/pshalgo.c (psh_glyph_compute_extrema, psh_glyph_interpolate_other_points): Ditto. * src/type1/t1load.c (T1_Set_MM_Blend): Ditto.
6adda68a	2014-02-28T09:24:26	Math simplifications. * src/cf2blues.c (cf2_blues_init): Use `FT_MulDiv'. * src/cf2ft.c (cf2_getScaleAndHintFlag): Use simple division.
135c3fae	2014-02-28T07:42:42	Fix Savannah bug #41697, part 2. * src/cff/cf2ft.c (cf2_initLocalRegionBuffer, cf2_initGlobalRegionBuffer): It is possible for a charstring to call a subroutine if no subroutines exist. This is an error but should not trigger an assert. Split the assert to account for this.
0eae6eb0	2014-02-28T07:40:01	Fix Savannah bug #41697, part 1. * src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is invalid. In this case, it is not safe to use the length of `hStemHintArray'; the exception has already been recorded in `hintMask'.
a2b5f66b	2014-02-26T19:50:18	[sfnt] Fix Savannah bug #41696. * src/sfnt/ttcmap.c (tt_cmap0_validate, tt_cmap2_validate, tt_cmap4_validate, tt_cmap14_validate): Fix limit tests.

08c628d1	2014-02-26T14:18:03	[cff] Fix Savannah bug #41693. * src/cff/cffload.c (CFF_Load_FD_Select): Reject empty array.
9a567640	2014-02-26T13:08:07	[bdf] Fix Savannah bug #41692. bdflib puts data from the input stream into a buffer in chunks of 1024 bytes. The data itself gets then parsed line by line, simply increasing the current pointer into the buffer; if the search for the final newline character exceeds the buffer size, more data gets read. However, in case the current line's end is very near to the buffer end, and the keyword to compare with is longer than the current line's length, an out-of-bounds read might happen since `memcmp' doesn't stop properly at the string end. * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons stop at string ends.
6b290fd2	2014-02-19T09:26:54	Fix Savannah bug #32902. Patch taken from https://code.google.com/p/sumatrapdf/source/browse/trunk/ext/_patches/freetype2.patch?spec=svn8620&r=8620#87 with slight modifications. * src/type1/t1parse.c (T1_Get_Private_Dict): Add heuristic test to handle fonts that incorrectly use \r at the beginning of an eexec block.
df14e6c0	2014-02-19T08:42:52	Fix Savannah bug #41590. * src/type1/t1load.c (parse_encoding): Protect against invalid number.
91c7a97b	2014-02-17T16:38:31	[autofit] Fix `make multi' compilation. * src/hbshim.c: Include `afglobal.h' and `aftypes.h'.
89a94d42	2014-02-12T23:45:47	[cff] Optimize by using `FT_MulDiv'. Suggested by Alexei. * src/cff/cf2font.c (cf2_computeDarkening): Do it.
7be2a94a	2014-02-08T13:55:38	Fix clang static analyzer and compiler warnings. * src/autofit/afhints.c (af_glyph_hints_align_weak_points), src/autofit/afloader (af_loader_load_g) <FT_GLYPH_FORMAT_COMPOSITE>, src/base/ftcalc.c (FT_MSB), src/base/ftoutln.c (FT_Outline_Decompose), src/bdf/bdfdrivr.c (bdf_interpret_style), src/cff/cffparse.c (cff_parse_integer), src/cid/cidparse.c (cid_parser_new), src/pfr/pfrload.c (pfr_phy_font_load), src/raster/ftraster.c (Decompose_Curve), src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/ttcmap.c (tt_cmap12_next, tt_cmap13_next), src/smooth/ftgrays.c (gray_hline): Remove dead code. * src/autofit/afmodule.c (af_property_get_face_globals, af_property_set, af_property_get), src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Make functions static. * src/base/ftobjs.c (ft_remove_renderer): Protect against library == NULL.

a8ceae40	2014-02-08T06:30:06	Fix Savannah bug #41507. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap) [!FT_CONFIG_OPTION_USE_PNG] <17, 17, 19>: Fix error handling.
355b359e	2014-02-08T06:23:04	[cff] Fix minor performance bug. * src/cff/cf2font.c (cf2_font_setup): Darkening amount and blue zone calculations are now cached and not recomputed on each glyph.
6dce1369	2014-02-05T15:40:47	Fix problems with perl 5.8.8 as distributed with current MinGW. * src/tools/afblue.pl: Work-around for Perl bug #63402. (string_re): Avoid `possessive quantifiers', which have been introduced in Perl version 5.10.
741f7366	2014-02-05T14:51:51	Work-around for Perl bug #63402.
a8772918	2014-02-04T11:36:08	[autofit] Minor fix. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths): Fix handling of alternative standard characters. This also fixes a compilation warning in non-debug mode.
ee3778d3	2014-02-03T11:16:47	[cff] Fix Savannah bug #41363. * src/cff/cf2ft.c (cf2_checkTransform): Convert assertion into parameter check. (cf2_decoder_parse_charstrings): Call `cf2_checkTransform' only if we are scaling the outline. (cf2_getPpemY): Remove problematic assertion.
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.
eb7691cc	2014-01-24T19:04:22	Fix Savannah bug #41320. * src/autofit/aflatin.c (af_latin_metrics_init_blues) <AF_LATIN_IS_LONG_BLUE>: Avoid negative index of `last'.
752f3912	2014-01-23T09:14:25	Fix Savannah bug #41310. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap) <glyph_format==5>: Don't check metrics, which this format doesn't have. This is another correction to the commit from 2013-11-21.
8b281f83	2014-01-23T08:14:53	Fix Savannah bug #41309. * src/type1/t1load.c (t1_parse_font_matrix): Properly handle result of `T1_ToFixedArray'. * src/cid/cidload.c (cid_parse_font_matrix): Synchronize with `t1_parse_font_matrix'. * src/type42/t42parse.c (t42_parse_font_matrix): Synchronize with `t1_parse_font_matrix'. (t42_parse_encoding): Synchronize with `t1_parse_encoding'. * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_BBOX>, <T1_FIELD_TYPE_MMOX>: Properly handle result of `ps_tofixedarray'.
039f0496	2014-01-23T07:48:23	Formatting.
ff8dc315	2014-01-22T09:19:57	* src/autofit/hbshim.c (af_get_coverage): Fix memory leaks.
aae0f1af	2014-01-19T18:27:18	Minor.
6a700786	2014-01-16T08:55:40	[autofit] Improve tracing of style coverages. * include/internal/fttrace.h: Add `afglobal' for tracing style coverages. * src/autofit/afglobal.c: Include FT_INTERNAL_DEBUG_H. (FT_COMPONENT): Define. (af_face_globals_compute_style_coverage): Trace `gstyles' array data.
2b623fe4	2014-01-15T09:46:23	Minor doc issues.
94c66944	2014-01-08T08:52:59	[arm] Fix Savannah bug #41138, part 2. * builds/unix/ftconfig.in (FT_MulFix_arm), include/config/ftconfig.h (FT_MulFix_arm), src/truetype/ttinterp.c (TT_MulFix14_arm): Fix preprocessor conditionals for `add.w'.
c46fa86b	2014-01-08T08:45:40	[autofit] Fix Savannah bug #41138, part 1. * src/tools/afblue.pl <Handling #endif>: Produce correct auxiliary enumeration names for generated `#else'. * src/autofit/afblue.h: Regenerated.
991cbcce	2014-01-05T13:24:56	[autofit] Minor fixes for `afblue.pl'. * src/tools/afblue.pl (aux_name): Don't use `reverse'. <Handling #endif>: Use proper indentation for generated `#else'. * src/autofit/afblue.h: Regenerated.
0d97744d	2014-01-04T11:46:34	[autofit] Fix Indic scripts. Split the single, incorrect Indic entry into separate scripts so that the covered ranges are the same: Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove entries for Meetai Mayak and Sharada – the Unicode ranges were incorrect (and nobody has complained about that), fonts are scarce for those scripts, and the Indic auto-hinter support is rudimentary anyways. * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK. * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro. Use it, together with AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK, to update. * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated. [!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed. Sort entries by tags.
ecdb0e35	2014-01-03T20:49:31	[autofit] Thinko. * src/autofit/hbshim.c (af_get_char_index): Similar to `af_get_coverage', reject glyphs which are not substituted.
1b5bc897	2014-01-03T18:33:24	[autofit] Fix handling of default coverages. With this commit, the implementation of coverage handling is completed. * src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to do. Reject coverages which don't contain appropriate glyphs for blue zones.
a42f9184	2014-01-03T18:29:41	[autofit] Fix handling of default coverages. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage): First handle non-default coverages, then the default coverage of the default script, and finally the other default coverages.
f45749b0	2014-01-03T18:09:36	[autofit] Fix scaling of HarfBuzz shaping. * src/autofit/hbshim.c (af_get_char_index): Scale to units per EM.
ea0367fb	2014-01-03T18:06:45	[autofit] Minor.
5c7f5500	2014-01-03T10:48:26	[autofit] Better ftgrid support. * src/autofit/afhints.c (af_glyph_hints_get_segment_offset): Add parameters `is_blue' and `blue_offset'.
55cd7e0a	2014-01-02T13:07:48	[autofit] Remove some styles. * src/autofit/afcover.h: Remove coverages for alternative fractions, denominators, numerators, and fractions. * src/autofit/afstyles.h (META_STYLE_LATIN): Updated.
c973e67b	2014-01-01T16:34:42	[autofit] Add more styles. * src/autofit/afstyles.h (STYLE_LATIN, META_STYLE_LATIN): New auxiliary macros; use them to define styles for Cyrillic, Greek, and Latin. * src/autofit/afcover.h: Remove coverage for oldstyle figures. Since those digits are used in combination with ordinary letters, it makes no sense to handle them separately. * src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit `options' parameter to 4 bits.
abb2f730	2014-01-01T08:00:16	[autofit] Fix style assignments to glyphs. * src/autofit/hbshim.c (af_get_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Scan GPOS coverage of features also so that we can skip glyphs that have both GSUB and GPOS data.
0950f3a5	2014-01-01T07:48:20	* src/autofit/hbshim.c: s/{lookups,glyphs}/gsub_{lookups,glyphs}/.
73cc8330	2014-01-01T07:10:36	[autofit] Implement and use `af_get_char_index' with HarfBuzz. * src/autofit/hbshim.c (COVERAGE) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Redefine to construct HarfBuzz features. (af_get_char_index) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Rewritten. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Use `y_offset' to adjust `best_y'.
785f3857	2013-12-31T09:45:10	[autofit] s/AF_STYLE_...._DEFAULT/AF_STYLE_...._DFLT/i.
c9d9947c	2013-12-31T08:16:57	[autofit] Fix interface of `af_get_char_index'. * src/autofit/hbshim.c (af_get_char_index): Return error value. Add argument for y offset (to be used in a yet-to-come patch). * src/autofit/hbshim.h, src/autofit/afcjk.c, src/autofit/aflatin.c: Updated.
44aa7e0a	2013-12-30T07:41:22	[autofit] Don't combine multiple features into one set. Combining them, as originally envisioned, would lead to much more complicated code, as investigations have shown meanwhile. The major drawback is that we run out of available style slots much earlier. However, this is only a theoretical issue since we don't support a large number of scripts currently. * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with a single-element `COVERAGE' macro, sort the elements by the feature tags, and add entry for `ruby'. * src/autofit/aftypes.h: Updated. * src/autofit/hbshim.c: Updated.

e2d2b154	2013-12-27T16:44:24	[ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when post resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to post resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType2 without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. http://lists.gnu.org/archive/html/freetype-devel/2013-02/msg00035.html http://lists.gnu.org/archive/html/freetype-devel/2013-12/msg00027.html * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Add a switch `sort_by_res_id' to control the fragmented resource ordering. * include/internal/ftrfork.h: Daclare new switch. * src/base/ftobjs.c (IsMacResource): Enable the soring for post resource, and disable the sorting for sfnt resource.

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.

3bf60950	2013-12-21T08:49:11	[autofit] Make PIC mode work actually. * src/autofit/afpic.h (AFModulePIC): Fix array sizes to fit the enumeration values automatically generated by including `afscript.h' and friends. * src/autofit/afpic.c (autofit_module_class_pic_init): Updated.
bd413862	2013-12-21T08:14:25	Fix PIC linking. * include/internal/ftrfork.h (CONST_FT_RFORK_RULE_ARRAY_BEGIN): Fix generated function name. * src/base/basepic.c (FT_Init_Table_raccess_guess_table): Rename to ... (FT_Init_Table_ft_raccess_guess_table): ... this so that the function name correctly corresponds to what the macro framework expects. * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so that PIC functions are compiled also.
c4e968ed	2013-12-21T07:23:08	[base] Add missing dependencies to Makefile. * src/base/rules.mk (BASE_SRC): Add `basepic.c' and `ftpic.c'. (BASE_H): Add `basepic.h'.
8a8f3758	2013-12-20T18:35:35	[autofit] Fix PIC compilation. * src/autofit/afcjk.c (af_cjk_metrics_init_widths), src/autofit/aflatin.c (af_latin_metrics_init_widths) [FT_CONFIG_OPTION_PIC]: Declare `globals'. * src/autofit/afglobal.c: Always call AF_DEFINE_SCRIPT_CLASS, and AF_DEFINE_STYLE_CLASS. * src/autofit/afpic.c: Include `afglobal.h'.

974b193b	2013-12-20T17:26:26	[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.

[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.

[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.

[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'.

[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.

Fix Savannah bug #41697, part 2. * src/cff/cf2ft.c (cf2_initLocalRegionBuffer, cf2_initGlobalRegionBuffer): It is possible for a charstring to call a subroutine if no subroutines exist. This is an error but should not trigger an assert. Split the assert to account for this.

[bdf] Fix Savannah bug #41692. bdflib puts data from the input stream into a buffer in chunks of 1024 bytes. The data itself gets then parsed line by line, simply increasing the current pointer into the buffer; if the search for the final newline character exceeds the buffer size, more data gets read. However, in case the current line's end is very near to the buffer end, and the keyword to compare with is longer than the current line's length, an out-of-bounds read might happen since `memcmp' doesn't stop properly at the string end. * src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons stop at string ends.

[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.

[autofit] Fix Indic scripts. Split the single, incorrect Indic entry into separate scripts so that the covered ranges are the same: Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese, Syloti Nagri, Tamil, Telugu, and Tibetan. At the same time, remove entries for Meetai Mayak and Sharada – the Unicode ranges were incorrect (and nobody has complained about that), fonts are scarce for those scripts, and the Indic auto-hinter support is rudimentary anyways. * src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK. * src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro. Use it, together with AF_CONFIG_OPTION_INDIC and AF_CONFIG_OPTION_CJK, to update. * src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.

[autofit] Don't combine multiple features into one set. Combining them, as originally envisioned, would lead to much more complicated code, as investigations have shown meanwhile. The major drawback is that we run out of available style slots much earlier. However, this is only a theoretical issue since we don't support a large number of scripts currently. * src/autofit/afcover.h: Replace `COVERAGE_{1,2,3}' macros with a single-element `COVERAGE' macro, sort the elements by the feature tags, and add entry for `ruby'. * src/autofit/aftypes.h: Updated. * src/autofit/hbshim.c: Updated.

[ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when post resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to post resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType2 without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. http://lists.gnu.org/archive/html/freetype-devel/2013-02/msg00035.html http://lists.gnu.org/archive/html/freetype-devel/2013-12/msg00027.html * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Add a switch `sort_by_res_id' to control the fragmented resource ordering. * include/internal/ftrfork.h: Daclare new switch. * src/base/ftobjs.c (IsMacResource): Enable the soring for post resource, and disable the sorting for sfnt resource.

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. (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.

[truetype] Fix positioning of composite glyphs. Problem reported by Nigel Tao <nigeltao@golang.org>. * src/truetype/ttgload.c (TT_Hint_Glyph): Remove code that shifts the glyph (component) by a fractional value computed from the LSB phantom point. This is wrong, since the horizontal phantom points get rounded horizontally later on.
