Werner Lemberg 082f2faf 2017-05-24T07:40:46 [bdf, pcf] Support ISO646.1991-IRV character encoding (aka ASCII). Problem reported by Marek Kašík <mkasik@redhat.com>, cf. https://bugzilla.redhat.com/show_bug.cgi?id=1451795 * src/bdf/bdfdrivr.c (BDF_Face_Init), src/pcf/pcfdrivr.c (PCF_Face_Init): Implement it.
Nikolaus Waxweiler a0455468 2017-05-20T07:28:46 [truetype] Always use interpreter v35 for B/W rendering (#51051). * src/truetype/ttgload.c (tt_loader_init) [TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Adjust `subpixel_hinting_lean', `grayscale_cleartype', and `vertical_lcd_lean' accordingly. * src/truetype/ttinterp.c (Ins_GETINFO): Updated. (TT_RunIns): Update `backward_compatibility' flag.
Alexei Podtelezhnikov ab2599ea 2017-05-20T00:35:21 [smooth] Implement minimal dynamic padding for LCD filtering. Extra bitmap padding for LCD filtering depends on the filter. The default 5-tap filter needs 2 extra subpixels. The light 3-tap filter needs only 1 extra subpixel. This space could be already available due to rounding. In order to optimize the padding, we now expand CBox for the given filter weights before rounding. This change breakes current Skia (and Firefox). * include/freetype/internal/ftobjs.h (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Remove `lcd_extra' field. * src/base/ftlcdfil.c (FT_Library_SetLcdFilterWeights, FT_Library_SetLcdFilter): Remove `lcd_extra' initializations. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Implement dymanic LCD padding.
Werner Lemberg 5efda13f 2017-05-15T21:26:01 [sfnt] Return proper scaling values for SBIX bitmaps. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Implement it.
Werner Lemberg 6e5445a2 2017-05-15T21:24:04 [truetype] Fix error handling for embedded bitmaps. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/truetype/ttgload.c (TT_Load_Glyph) [TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: Handle error if font is not scalable.
Alexei Podtelezhnikov a7f276a2 2017-05-15T00:25:37 [autofit] Make autohint warping NORMAL option. This moves warping option from LIGHT to NORMAL mode. This makes LIGHT truly void of hinting in x-direction, with left side bearing never changed and right side bearing only altered by advance rounding. Therefore, LIGHT is now ready to return fractional advance. As a NORMAL option, warping substitutes normal hinting. * src/autofit/afcjk.c (af_cjk_hints_apply): Updated. * src/autofit/aflatin.c (af_latin_hints_apply): Updated. * src/autofit/aflatin2.c (af_latin2_hints_apply): Updated. * src/autofit/afloader.c (af_loader_load_glyph): Handle warping phantom points as normal.

Behdad Esfahbod 60bf264e 2017-05-02T14:38:54 [truetype] Make `IUP' gvar deltas do the same as Apple (#50832). When points are not touched by gvar interpolation deltas, FreeType gave a slightly different result than Apple's CoreText. The OpenType working group will update the specification to document the following behaviour: If the two points with deltas to the `left' and `right' of the untouched point have the same coordinate, then the inferred delta for the untouched point should be zero. * src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new behaviour.
Werner Lemberg ba40054c 2017-05-02T12:32:19 [autofit] Remove `slight' auto-hint mode again.

Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and Nikolaus Waxweiler <madigens@gmail.com>. * src/base/ftobjs.c (FT_Request_Size): Trigger recomputation of auto-hinter metrics. Without this change, multiple size changing calls for a single face fail.
Werner Lemberg 785833d9 2017-04-29T06:47:14 * src/truetype/ttdriver.c (tt_size_request): Properly check `error'. Reported by Earnestly <zibeon@googlemail.com> in http://lists.nongnu.org/archive/html/freetype/2017-04/msg00031.html
Werner Lemberg 0a5315d1 2017-04-27T13:02:24 Introduce AF_CONFIG_OPTION_TT_SIZE_METRICS configuration option. * include/freetype/config/ftoption.h (AF_CONFIG_OPTION_TT_SIZE_METRICS): New option, commented out by default. * src/autofit/afloader.c (af_loader_load_glyph): Use AF_CONFIG_OPTION_TT_SIZE_METRICS to guard the corresponding code.
Werner Lemberg ab10ffcd 2017-04-26T13:41:40 * include/freetype/freetype.h (FT_Render_Mode): Fix order. This retains backwards compatibility. Noted by Alexei.
Werner Lemberg 5f18d867 2017-04-22T23:02:21 [truetype] Do linear scaling for FT_LOAD_NO_HINTING (#50470). * src/truetype/ttobs.h (TT_SizeRec): Add field `hinted_metrics' to hold hinted metrics. Make `metrics' a pointer so that `tt_glyph_load' can easily switch between metrics. * src/truetype/ttdriver.c (tt_size_request): Updated. (tt_glyph_load): Use top-level metrics if FT_LOAD_NO_HINTING is used. * src/truetype/ttgload.c (TT_Hint_Glyph, TT_Process_Simple_Glyph, TT_Process_Composite_Component, load_truetype_glyph, compute_glyph_metrics, TT_Load_Glyph): Updated. * src/truetype/ttinterp.c (TT_Load_Context): Updated. * src/truetype/ttobjs.c (tt_size_reset): Updated. * src/truetype/ttsubpix.c (sph_set_tweaks): Updated.
Werner Lemberg 5aa6716a 2017-04-22T13:27:21 Add new `slight' auto-hinting mode. This mode uses fractional advance widths and doesn't scale glyphs horizontally, only applying vertical scaling and hinting. At the same time, the behaviour of the `light' auto-hinter gets restored for backwards compatibility: Both vertical and horizontal scaling is again based on rounded metrics values (this was changed in a commit from 2017-03-30 as a side effect). To be more precise, the behaviour is restored for TrueType fonts only; for other font formats like Type 1, this is a new feature of the `light' hinting mode. * include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro. (FT_RENDER_MODE_SLIGHT): New render mode. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add `autohint_mode' and `autohint_metrics' fields. * src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c (af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init): Updated. * src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use `autohint_metrics'. (af_loader_load_glyph): s/internal/slot_internal/. Initialize `autohint_metrics' and `autohint_mode' depending on current auto-hint mode. Use `autohint_metrics'. Updated. * src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated. * src/base/ftobjs.c (FT_Load_Glyph): Updated. (FT_New_Size): Allocate `internal' object. * src/pshinter/pshalgo.c (ps_hints_apply): Updated. * src/smooth/ftsmooth.c (ft_smooth_render): Updated.
Werner Lemberg 5412d886 2017-04-22T12:48:50 Introduce `FT_Size_InternalRec' structure. We are going to extend this later on. * include/freetype/internal/ftobjs.h (FT_Size_InternalRec): New structure with a single field `module_data'. * src/base/ftobjs.c (FT_New_Size): Allocate `internal' field of `FT_Size' structure. * src/cff/cffgload.c (cff_builder_init, cff_decoder_prepare): Use `size->internal->module_data' instead of `size->internal'. * src/cff/cffobjs.c (cff_size_done): Deallocate `module_data'. (cff_size_init, cff_size_select, cff_size_request): Use `size->internal->module_data' instead of `size->internal'. * src/cif/cidobjs.c (cid_size_done, cid_size_init, cid_size_request): Use `size->internal->module_data' instead of `size->internal'. * src/psaux/psobjs.c (t1_builder_ini): Use `size->internal->module_data' instead of `size->internal'. * src/type1/t1objs.c (T1_Size_Done, T1_Size_Init, T1_Size_Request): Use `size->internal->module_data' instead of `size->internal'.
Alexei Podtelezhnikov eb5e0fb7 2017-04-21T22:53:39 * src/smooth/ftsmooth.h: Remove unused guards and declaration.
Alexei Podtelezhnikov 71d289da 2017-04-19T23:50:29 Typos.

(TT_RunIns): Don't enforce reexecution of `fpgm' and `prep' bytecode in case of error since function tables can no longer be modified (due to the changes in `Ins_FDEF' and `Ins_IDEF'). This change can enormously speed up handling of broken fonts.
Alexei Podtelezhnikov e7b01304 2017-04-02T22:01:47 [autofit] Disable metrics adjustment for `FT_LOAD_TARGET_LCD'. * src/autofit/aflatin.c (af_latin_hints_init): Updated. * src/autofit/aflatin2.c (af_latin2_hints_init): Ditto.

Werner Lemberg 5a3490e0 2017-03-31T09:35:58 * src/cff/cffload.c (cff_font_load): Improve fix from 2017-01-04. Allow CFFs containing a single font to have an empty font name. Problem reported by 張俊芝 <418092625@qq.com> in http://lists.nongnu.org/archive/html/freetype-devel/2017-03/msg00074.html
Werner Lemberg c8c67639 2017-03-30T21:07:17 * src/cff/cffparse.h (CFF2_DEFAULT_STACK): Set to 513 also. Requested by Dave Arnold.
Werner Lemberg da38be83 2017-03-30T13:24:03 [truetype] Fix HVAR and VVAR handling (#50678). * src/truetype/ttgxvar.c (tt_hvadvance_adjust): Handle glyph indices larger than `mapCount' as described in the specification.
Werner Lemberg bcc74f4d 2017-03-30T13:14:43 [truetype] Allow linear scaling for unhinted rendering (#50470). * src/truetype/ttdriver.c (tt_size_request): Revert change from 2011-07-16; the intended metrics fix seems now to be implemented in a different way, making the patch unnecessary. Note that this change was usually patched out by all major GNU/Linux distributions due to heavy side effects. * src/truetype/ttgload.c (compute_glyph_metrics, TT_Load_Glyph): Refer to the metrics of the `TT_Size' object.
Werner Lemberg 1ede3674 2017-03-30T00:26:31 [truetype] Fix thinko related to PS name of default named instance. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `strid' and `psid' are name ID values, not indices into the array of name entries.
Werner Lemberg 208e712d 2017-03-27T20:56:23 [cid, truetype] Don't use `index' as a variable name. At least on FreeBSD there is a global declaration of `index' in file `/usr/include/strings.h'. * src/cff/cf2intrp.c, src/truetype/ttgload.c: s/index/idx/ where appropriate.
Wojciech Mamrak 565f5a7d 2017-03-27T09:19:14 [sfnt] Minor improvement for handling kern tables. * src/sfnt/ttkern.c (tt_face_load_kern): Don't check for cross-stream kerning tables since we reject format 2 tables later on anyways. Modify code for limit test... (tt_face_get_kerning): ... to avoid a limit test here.
Werner Lemberg c22a9aa2 2017-03-27T07:57:24 [pcf] Fix compiler warnings. Reported by Alexander Hedges <ahedges@student.ethz.ch>. * src/pcf/pcfdrivr.c (pcf_property_set, pcf_property_get): Tag `property_name' with `FT_UNUSED' where necessary.

Werner Lemberg f958c48e 2017-03-24T09:15:10 [psaux] Better protect `flex' handling. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=935 * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <callothersubr>: Since there is not a single flex operator but a series of subroutine calls, malformed fonts can call arbitrary other operators after the start of a flex, possibly adding points. For this reason we have to check the available number of points before inserting a point.
Werner Lemberg 913f436d 2017-03-23T18:37:06 [sfnt] Fix check for default named instance. * src/sfnt/sfobjs.c (sfnt_init_face): A `fixed' number needs four bytes, not two...

Werner Lemberg 683e3ad9 2017-03-21T19:49:11 [truetype] Some variable renamings. Too much local variables holding different structures were called `metrics'. * src/truetype/ttdriver.c (tt_size_select): s/metrics/size_metrics/. * src/truetype/ttgload.c (tt_get_metrics_incr_overrids, compute_glyph_metrics): s/metrics/incr_metrics/.

Werner Lemberg 3e79254a 2017-03-18T10:06:15 * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#50573). The problematic font that exceeds the old limit is Lato-Regular, version 2.007, containing bytecode generated by a buggy version of ttfautohint.
Werner Lemberg 13fa85a2 2017-03-18T09:42:58 [truetype] Another limitation for bytecode loop count maximum. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=900 * src/truetype/ttinterp.c (TT_RunIns): Limit `loopcall_counter_max' by number of glyphs also.
Werner Lemberg ab840e6a 2017-03-18T08:50:42 [ftfuzzer] Minor improvement. * src/tools/ftfuzzer/ftfuzzer.cc: Don't set intermediate axis if bitmap strikes are active.

Werner Lemberg 77930974 2017-03-07T17:27:58 [sfnt] Improve handling for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=738 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `glyf' present also (which gets priority).
Werner Lemberg 27fee7f8 2017-03-06T20:45:44 [sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances. Sythesize a named instance entry if necessary. (tt_done_blend): Free `normalized_stylecoords'.
