To 24 support this I use the face_index argument of FT_(Open|New)_Face() 25 functions, and pretend the suitcase file is a collection. 26 27 Warning: fbit and NFNT bitmap resources are not supported yet. In old 28 sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' 29 resources instead of the `bdat' table in the sfnt resource. Therefore, 30 face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' 31 resource is unavailable at present. 32 33 The Mac FOND support works roughly like this: 34 35 - Check whether the offered stream points to a Mac suitcase file. This 36 is done by checking the file type: it has to be 'FFIL' or 'tfil'. The 37 stream that gets passed to our init_face() routine is a stdio stream, 38 which isn't usable for us, since the FOND resources live in the 39 resource fork. So we just grab the stream->pathname field. 40 41 - Read the FOND resource into memory, then check whether there is a 42 TrueType font and/or(!) a Type 1 font available. 43 44 - If there is a Type 1 font available (as a separate `LWFN' file), read 45 its data into memory, massage it slightly so it becomes PFB data, wrap 46 it into a memory stream, load the Type 1 driver and delegate the rest 47 of the work to it by calling FT_Open_Face(). (XXX TODO: after this 48 has been done, the kerning data from the FOND resource should be 49 appended to the face: On the Mac there are usually no AFM files 50 available. However, this is tricky since we need to map Mac char 51 codes to ps glyph names to glyph ID's...) 52 53 - If there is a TrueType font (an `sfnt' resource), read it into memory, 54 wrap it into a memory stream, load the TrueType driver and delegate 55 the rest of the work to it, by calling FT_Open_Face(). 56 57 - Some suitcase fonts (notably Onyx) might point the `LWFN' file to 58 itself, even though it doesn't contains `POST' resources. To handle 59 this special case without opening the file an extra time, we just 60 ignore errors from the `LWFN' and fallback to the `sfnt' if both are 61 available. 62 */ 63 64 65 #include <ft2build.h> 66 #include FT_FREETYPE_H 67 #include FT_TRUETYPE_TAGS_H 68 #include FT_INTERNAL_STREAM_H 69 #include "ftbase.h" 70 71 #if defined( __GNUC__ ) || defined( __IBMC__ ) 72 /* This is for Mac OS X.
