To - support this I use the face_index argument of FT_(Open|New)_Face() - functions, and pretend the suitcase file is a collection. - - Warning: Although the FOND driver sets face->num_faces field to the - number of available fonts, but the Type 1 driver sets it to 1 anyway. - So this field is currently not reliable, and I don't see a clean way - to resolve that. The face_index argument translates to - - Get1IndResource( 'FOND', face_index + 1 ); - - so clients should figure out the resource index of the FOND. - (I'll try to provide some example code for this at some point.) - - 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(). - */ - - -#include <ft2build.h> -#include FT_FREETYPE_H -#include FT_INTERNAL_STREAM_H - -#ifdef __GNUC__ -#include "../truetype/ttobjs.h" -#include "../type1/t1objs.h" - /* This is for Mac OS X.
