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 <ft2build.h> -#include FT_FREETYPE_H -#include FT_TRUETYPE_TAGS_H -#include FT_INTERNAL_STREAM_H -#include "ftbase.h" - -#if defined( __GNUC__ ) || defined( __IBMC__ ) - /* This is for Mac OS X.
