The effect - is to use a previous darkening amount when producing an unhinted, - unscaled outline. This can cause autohint samples in ftgrid and - ftview to be based on darkened CFF outlines instead of unhinted, - undarkened ones. - -2013-09-29 Dave Arnold <darnold@adobe.com> - - Fix Savannah bug #39295. - - The bug was caused by switching to the initial hintmap (the one in - effect when `moveto' executes) just before drawing the final element - in the charstring. This ensured that the path was closed (in both - Character Space and Device Space). But if the final element was a - curve and if the final hintmap was different enough from the initial - one, then the curve was visibly distorted. - - The first part of the fix is to draw the final curve using the final - hintmap as specified by the charstring. This corrects the - distortion but does not ensure closing in Device Space. It may - require the rasterizer to automatically generate an extra closing - line. Depending on the hintmap differences, this line could be from - zero to a couple pixels in length. - - The second part of the fix covers the case where the charstring - subpath is closed with an explicit line. We now modify that line's - end point to avoid the distortion. - - Some glyphs in the bug report font (TexGyreHeros-Regular) that show - the change are: - - 25ppem S (98) - 24ppem eight (52) - 25.5ppem p (85) - - Curves at the *end* of a subpath are no longer distorted. However, - some of these glyphs have bad hint substitutions in the middle of a - subpath, and these are not affected. - - The patch has been tested with a set of 106 fonts that shipped with - Adobe Creative Suite 4, together with 756 Open Source CFF fonts from - Google Fonts. There are 1.5 million glyphs, of which some 20k are - changed with the fix. A sampling of a few hundred of these changes - have been examined more closely, and the changes look good (or at - least acceptable). - - * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' - to indicate that we synthesize a closepath line. - - * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. - (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for - `lineto' operator) and adjust hint zone. - For synthesized closing lines, use end point in first hint zone. - (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In - particular, shift the detection of zero-length lines from character - space to device space. - (cf2_glyphpath_closeOpenPath): Remove assertion. - Updated. - -2013-09-25 Werner Lemberg <wl@gnu.org> - - * src/autofit/aflatin.c (af_{grek,cyrl}_uniranges): Fix arrays. - -2013-09-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> - - [bdf, pcf] Refuse non-zero face_index. - - Suggested by Akira Tagoh, see - - http://lists.gnu.org/archive/html/freetype/2013-09/msg00030.html - - * src/bdf/bdfdrivr.c (BDF_Face_Init): Return `Invalid_Argument' - error if the font could be opened but non-zero `face_index' is - given. - * src/pcf/pcfdrivr.c (PCF_Face_Init): Ditto. + * src/truetype/ttinterp.c (TT_Load_Context): Updated. + (Ins_MPS): Fix instruction. - * src/type42/t42objs.c (T42_Face_Init): Remove unrequired FT_UNUSED - macro for `face_index' because it is validated later. +2016-08-16 Werner Lemberg <wl@gnu.org> -2013-09-23 Werner Lemberg <wl@gnu.org> + [lzw] Optimize last commit. - Fix Savannah bug #40090. + * src/lzw/ftzopen.c (ft_lzwstate_get_code): Move check into + conditional clause. - * src/autofit/afcjk.c (af_cjk_metrics_scale): Revert commit - 306f8c5d (from 2013-08-25) affecting this function. +2016-08-16 Werner Lemberg <wl@gnu.org> -2013-09-22 Werner Lemberg <wl@gnu.org> + [lzw] Avoid invalid left shift. - [autofit] Disunify Cyrillic and Greek handling from Latin. + Reported as - * src/autofit/afscript.h: Add Cyrillic and Greek. + https://bugzilla.mozilla.org/show_bug.cgi?id=1295366 - * src/autofit/afblue.dat (AF_BLUE_STRINGSET_GREK, - AF_BLUE_STRINGSET_CYRL): Add blue zones for Greek and Cyrillic. - (AF_BLUE_STRINGSET_LATN): Fix typo. - * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. - - * src/autofit/aflatin.c (af_grek_uniranges, af_cyrl_uniranges): New - arrays. - (af_grek_script_class, af_cyrl_script_class): New scripts. - * src/autofit/aflatin.h: Updated. - -2013-09-20 Werner Lemberg <wl@gnu.org> - - * docs/CHANGES: Updated. - -2013-09-20 Behdad Esfahbod <behdad@behdad.org> - - Fix vertical size of emboldened glyphs. - - Cf. https://bugzilla.gnome.org/show_bug.cgi?id=686709 - - * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Adjust `horiBearingY' - also. - -2013-09-11 Alexei Podtelezhnikov <apodtele@gmail.com> - - * include/freetype/ftoutln.h: Correct FT_Outline_Get_Orientation - algorithm description. - -2013-09-11 Werner Lemberg <wl@gnu.org> - - [autofit] Improve Hebrew rendering. - - This change introduces a new blue zone property - `AF_BLUE_PROPERTY_LATIN_LONG' to make the auto-hinter ignore short - top segments. - - * src/autofit/afblue.dat: Fix Hebrew blue strings. - Use AF_BLUE_PROPERTY_LATIN_LONG for AF_BLUE_STRING_HEBREW_TOP. - - * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_LONG): New macro. - - * src/autofit/afblue.c, src/autofit/afblue.h: Updated. - - * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle - `AF_LATIN_IS_LONG_BLUE'. - - * src/autofit/aflatin.h (AF_LATIN_IS_LONG_BLUE): New macro. - -2013-08-28 Behdad Esfahbod <behdad@google.com> - - [sfnt] Fix frame access while reading WOFF table directory. - - * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame - while reading the directory entries for the whole loop. - -2013-08-29 Werner Lemberg <wl@gnu.org> - Behdad Esfahbod <behdad@google.com> - - Implement support for WOFF containers. - - We simply synthesize a SFNT from the WOFF, create a memory stream - for the new data, and load the SFNT as usual. - - Does NOT add any API to access WOFF metadata or private blocks. - - * include/freetype/internal/tttypes.h (WOFF_HeaderRec, - WOFF_TableRec): New structures. - - * include/freetype/tttags.h (TTAG_wOFF): New macro. - - * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling - `open_face'. - - * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include - `FT_GZIP_H'. - (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for - writing to a stream. - (sfnt_stream_close, compare_offsets, woff_open_font): New functions. - (sfnt_open_font): Handle `TTAG_wOFF'. - (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. - - * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling - `sfnt->init_face'. - - * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an - argument so that a changed stream survives. - Update callers. - -2013-08-28 Werner Lemberg <wl@gnu.org> - - [gzip] New function `FT_Gzip_Uncompress'. - - This is modeled after zlib's `uncompress' function.
