e0015f76	2018-05-08T11:51:16	[autofit] Avoid potential SEGV if running out of memory. Problem reported by Shailesh Mistry <shailesh.mistry@hotmail.co.uk>. * src/autofit/afshaper.c (af_shaper_buf_create, af_shaper_buf_destroy) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Don't allocate and free a four-byte buffer. Instead, make those functions no-ops; the calling functions will provide a pointer to a buffer instead. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_metrics_init_blues, af_cjk_metrics_check_digits), src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues, af_latin_metrics_check_digits) [!FT_CONFIG_OPTION_USE_HARFBUZZ]: Use pointer to local variable for `shaper_buf'.

2df73b39	2017-12-18T23:32:32	[sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131). Before this commit, the iterator wasn't able to correctly handle a sub-header for higher byte 0x01. * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment for outer loop.

40db4a99	2017-11-27T22:17:41	Allow (again) encoding vectors with more than 256 elements (#52464). In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it.
2f1863cf	2017-11-23T20:40:52	Silence unused function warnings. Some static function declarations cause unused function warnings if certain config options are turned off via `ftoption.h'. * src/base/ftbase.h, src/base/ftrfork.c, src/sfnt/ttbdf.h, src/truetype/ttgxvar.h: Add #ifdef guards around these sections.

b9bd2d14	2017-11-22T12:32:47	[psaux] Fix CFF advance widths. (#52466) Glyph advance widths were being written to the new `PS_Decoder' but not saved to the underlying format specific decoder. This caused pure CFF fonts to have bad advance width. * include/freetype/internal/psaux.h (PS_Decoder): Change `glyph_width' field to pointer. Remove unused fields. * src/psaux/psobjs.c (ps_decoder_init): Change `glyph_width' from copy to reference. Remove unused. * src/psaux/psft.c (cf2_setGlyphWidth): Update code.
a364e38a	2017-11-14T07:54:53	Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe

cdab9cfa	2017-10-21T16:36:49	[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding.
77b34e01	2017-11-03T16:13:29	[truetype] Add more tricky fonts. See the report by Yang Yinsen. https://lists.gnu.org/archive/html/freetype-devel/2017-11/msg00000.html * src/truetype/ttobjs.c (trick_names): Add `DFGothic-EB', `DFGyoSho-Lt', `DFHSGothic-W5', `DFHSMincho-W3' and `DFHSMincho-W7'. (tt_check_trickyness_sfnt_ids): Add checksums for DFGothic-EB, DFGyoSho-Lt, DFHSGothic-W5, DFHSMincho-W3 and DFHSMincho-W7. Also add checksums for DLCLiShu and DLCHayBold which their family names were already listed but their checksums were previously unknown.
81651636	2017-11-01T22:51:03	[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.
91015cb4	2017-10-21T22:57:43	[smooth] Improve complex rendering at high ppem. At large sizes almost but not exactly horizontal segments can quickly drain the rendering pool. This patch at least avoids filling the pool with trivial cells. Beyond this, we can only increase the pool size. Reported, analyzed, and tested by Colin Fahey. * src/smooth/ftgrays.c (gray_set_cell): Do not record trivial cells.

[sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131). Before this commit, the iterator wasn't able to correctly handle a sub-header for higher byte 0x01. * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment for outer loop.

Allow (again) encoding vectors with more than 256 elements (#52464). In version 2.6.1, this has been disallowed to better reject malformed fonts; however, this restriction was too strong. This time, we only take the first 256 elements into account, since encoding arrays are always accessed with a 8bit integer, according to the PostScript Language Reference. * src/type1/t1load.c (parse_encoding): Implement it.

Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f). However, some charstrings use `endchar' in a final subroutine call, rewinding to the start of that subroutine, and only a small section of the actual glyph is drawn. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdENDCHAR>: Ensure we are on the top level charstring before rewinding.

[smooth] Fix complex rendering at high ppem. We used to split large glyphs into horizontal bands and continue bisecting them still horizontally if that was not enough. This is guaranteed to fail when a single scanline cannot fit into the rendering memory pool. Now we bisect the bands vertically so that the smallest unit is a column of the band height, which is guranteed to fit into memory. * src/smooth/ftgrays.c (gray_convert_glyph): Implement it.
