Another possibility + would be resetting `decoder->metrics_loaded' to false before + loading each composite component. However, we must restore the + original metrics after finishing the recursion; otherwise we can + get a misaligned glyph. + + . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos', + causing some glyph components to be shifted too far to the right + (especially noticeable for small sizes). + + Note that support for grayscale bitmaps (not necessarily compound) is + completely broken in ttsbit0.c. + + * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics. + (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case + of `h == height'. + (tt_sbit_decoder_load_compound): Reset metrics after loading + components. + Allocate bitmap. + +2009-03-09 Werner Lemberg <wl@gnu.org> + + * builds/unix/configure.raw (version_info): Set to 9:20:3. + +2009-03-03 David Turner <david@freetype.org> + + Protect SFNT kerning table parser against malformed tables. + + This closes Savannah BUG #25750. + + * src/sfnt/ttkern.c (tt_face_load_kern, tt_face_get_kerning): Fix a + bug where a malformed table would be successfully loaded but later + crash the engine during parsing. + +2009-03-03 David Turner <david@freetype.org> + + Update documentation and bump version number to 2.3.9. + + * include/freetype/freetype.h: Bump patch version to 9. + * docs/CHANGES: Document the ABI break in 2.3.8. + * docs/VERSION.DLL: Update version numbers table for 2.3.9. + +2009-03-03 David Turner <david@freetype.org> + + Remove ABI-breaking field in public PS_InfoFontRec definition. + + Instead, we define a new internal PS_FontExtraRec structure to + hold the additionnal field, then place it in various internal + positions of the corresponding FT_Face derived objects. + + * include/freetype/t1tables.h (PS_FontInfoRec): Remove the + `fs_type' field from the public structure. + * include/freetype/internal/psaux.h (T1_FieldLocation): New + enumeration `T1_FIELD_LOCATION_FONT_EXTRA'. + * include/freetype/internal/t1types.h (PS_FontExtraRec): New + structure. + (T1_FontRec, CID_FaceRec): Add it. + + * src/cid/cidload.c (cid_load_keyword): Handle + T1_FIELD_LOCATION_FONT_EXTRA. + * src/cid/cidtoken.h, src/type1/t1tokens.h, src/type42/t42parse.c: + Adjust FT_STRUCTURE and T1CODE properly to handle `FSType'. + * src/type1/t1load.c (t1_load_keyword): Handle + T1_FIELD_LOCATION_FONT_EXTRA. + + * include/freetype/internal/services/svpsinfo.h (PsInfo service): + Add `PS_GetFontExtraFunc' function typedef. + + * src/base/ftfstype.c: Include FT_INTERNAL_SERVICE_H and + FT_SERVICE_POSTSCRIPT_INFO_H. + (FT_Get_FSType_Flags): Use POSTSCRIPT_INFO service. + + * src/cff/cffdrivr.c (cff_service_ps_info): Updated. + * src/cid/cidriver.c (cid_ps_get_font_extra): New function. + (cid_service_ps_info): Updated. + * src/type1/t1driver.c (t1_ps_get_font_extra): New function. + (t1_service_ps_info): Updated. + * src/type42/t42drivr.c (t42_ps_get_font_extra): New function. + (t42_service_ps_info): Updated. + +2009-03-02 Alexey Kryukov <anagnost@yandex.ru> + + Fix handling of EBDT formats 8 and 9. + + The main cycle in `blit_sbit' makes too many iterations: it actually + needs the count of lines in the source bitmap rather than in the + target image. + + * src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]: + Add parameter `source_height' and use it for main loop. + (Load_SBit_Single) [FT_CONFIG_OPTION_OLD_INTERNALS]: Updated. + +2009-02-23 Werner Lemberg <wl@gnu.org> + + Fix Savannah bug #25669. + + * src/base/ftadvanc.h (FT_Get_Advances): Fix serious typo. + + * src/base/ftobjs.c (FT_Select_Metrics, FT_Request_Metrics): Fix + scaling factor for non-scalable fonts. + + * src/cff/cffdrivr.c (cff_get_advances): Use correct advance width + value to prevent incorrect scaling. + + * docs/CHANGES: Document it. + +2009-02-15 Matt Godbolt <matt@godbolt.org> + + Fix Savannah bug #25588. + + * builds/unix/ftconfig.in (FT_MulFix_arm): Use correct syntax for + `orr' instruction. + +2009-02-11 Werner Lemberg <wl@gnu.org> + + * src/truetype/ttobjs.c (tt_check_trickyness): Add `DFKaiShu'. + Reported by David Bevan <dbevan@emtex.com>. + +2009-02-09 Werner Lemberg <wl@gnu.org> + + Fix Savannah bug #25495. + + * src/sfnt/sfobjs.c (sfnt_load_face): Test for bitmap strikes before + setting metrics and bbox values.
