To + support this I use the face_index argument of FT_(Open|New)_Face() + functions, and pretend the suitcase file is a collection. + + Warning: fbit and NFNT bitmap resources are not supported yet. In old + sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' + resources instead of the `bdat' table in the sfnt resource. Therefore, + face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' + resource is unavailable at present. + + The Mac FOND support works roughly like this: + + - Check whether the offered stream points to a Mac suitcase file. This + is done by checking the file type: it has to be 'FFIL' or 'tfil'. The + stream that gets passed to our init_face() routine is a stdio stream, + which isn't usable for us, since the FOND resources live in the + resource fork. So we just grab the stream->pathname field. + + - Read the FOND resource into memory, then check whether there is a + TrueType font and/or(!) a Type 1 font available. + + - If there is a Type 1 font available (as a separate `LWFN' file), read + its data into memory, massage it slightly so it becomes PFB data, wrap + it into a memory stream, load the Type 1 driver and delegate the rest + of the work to it by calling FT_Open_Face(). (XXX TODO: after this + has been done, the kerning data from the FOND resource should be + appended to the face: On the Mac there are usually no AFM files + available. However, this is tricky since we need to map Mac char + codes to ps glyph names to glyph ID's...) + + - If there is a TrueType font (an `sfnt' resource), read it into memory, + wrap it into a memory stream, load the TrueType driver and delegate + the rest of the work to it, by calling FT_Open_Face(). + + - Some suitcase fonts (notably Onyx) might point the `LWFN' file to + itself, even though it doesn't contains `POST' resources. To handle + this special case without opening the file an extra time, we just + ignore errors from the `LWFN' and fallback to the `sfnt' if both are + available. + */ + + +#include +#include FT_FREETYPE_H +#include FT_TRUETYPE_TAGS_H +#include FT_INTERNAL_STREAM_H +#include "ftbase.h" + + /* This is for Mac OS X.
