| Notes |
| |
| Mac suitcase files can (and often do!) contain multiple fonts. 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(). |
