Graham Asher 11f0ab7d 2002-07-24T13:58:21 FIX for bug reported by Sven Neumann [sven@gimp.org] on the FreeType development forum: "If FT_CONFIG_OPTION_INCREMENTAL is undefined (this is the default), the TrueType loader crashes in line 852 of src/truetype/ttgload.c when it tries to access face->glyph_locations.".
Graham Asher 320da730 2002-07-19T11:40:51 More work on supporting fonts passed from GhostScript: sfnt_dir_check now ignores the tables 'glyx' and 'locx' which are hacked-out versions of 'glyf' and 'loca' in some PostScript Type 42 fonts, and will generally be invalid.
Graham Asher bd8b0851 2002-07-18T16:57:43 Added support for incrementally loaded Type 1 faces.
Graham Asher cd0d1dfa 2002-07-18T16:38:07 Changes to support incremental Type 42 fonts: assume a font has glyphs if it has an incremental interface object.

Graham Asher 03011c64 2002-07-18T15:02:08 Added a new configuration macro, FT_CONFIG_OPTION_INCREMENTAL, to enable incremental face loading. By default it is not defined.

David Turner 665f30d3 2002-05-28T20:14:28 * include/freetype/ftbdf.h: adding documentation comments for the API reference describing the new function FT_Get_BDF_Charset_ID.
Werner Lemberg 877ff678 2002-05-28T06:03:10 * src/base/ftnames.c (FT_Get_Sfnt_Name): Don't use FT_STREAM_READ_AT but FT_STREAM_READ. Declare `stream' variable.
David Turner 791d83a6 2002-05-27T23:52:01 * include/freetype/internal/tttypes.h, src/sfnt/ttload.c, src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c: fixing the SFNT name table loader to support various buggy fonts. it now ignores empty name entries, entries with invalid pointer offsets and certain fonts containing tables with broken "storageOffset" fields. name strings are now loaded on demand, which reduces the memory requirements for a given FT_Face tremendously (for example, the name table of Arial.ttf is about 10Kb and contains 70 names !!) finally, this is a _quick_ fix. The whole name table loader and interface will be rewritten in a much more cleanly way shortly, once CSEH have been introduced in the sources.
Werner Lemberg 4d631e44 2002-05-27T13:02:37 Fix comment.
Werner Lemberg 62c2096a 2002-05-24T22:05:43 * builds/unix/ft-munmap.m4: New file, extracted FT_MUNMAP_DECL and FT_MUNMAP_PARAM from aclocal.m4 into here, so aclocal.m4 can be rebuilt from sources. Set macro serial to 1, and use third argument to AC_DEFINE for our two custom symbols, so ftconfig.in could one day be rebuilt with autoheader (not recommended now, ftconfig.in is a custom source file)
Werner Lemberg 233302a8 2002-05-22T05:41:06 * include/freetype/config/ftheader.h (FT_BEZIER_H): Removed. (FT_BDF_H): New macro for accessing `ftbdf.h'. * src/type42/t42drivr.c (hexval): Fix typo.
