root :: The parent module. face_object_size :: The size of a face object in bytes. size_object_size :: The size of a size object in bytes. slot_object_size :: The size of a glyph object in bytes. init_face :: The format-specific face constructor. done_face :: The format-specific face destructor. init_size :: The format-specific size constructor. done_size :: The format-specific size destructor. init_slot :: The format-specific slot constructor. done_slot :: The format-specific slot destructor. set_char_sizes :: A handle to a function used to set the new character size in points + resolution. Can be set to 0 to indicate default behaviour. set_pixel_sizes :: A handle to a function used to set the new character size in pixels. Can be set to 0 to indicate default behaviour. load_glyph :: A function handle to load a given glyph image in a slot. This field is mandatory! get_char_index :: A function handle to return the glyph index of a given character for a given charmap. This field is mandatory! get_kerning :: A function handle to return the unscaled kerning for a given pair of glyphs. Can be set to 0 if the format doesn't support kerning. attach_file :: This function handle is used to read additional data for a face from another file/stream. For example, this can be used to add data from AFM or PFM files on a Type 1 face, or a CIDMap on a CID-keyed face. get_advances :: A function handle used to return the advances of 'count' glyphs, starting at `index'. the `vertical' flags must be set when vertical advances are queried. The advances buffer is caller-allocated.

Notes: Most function pointers, with the exception of `load_glyph' and `get_char_index' can be set to 0 to indicate a default behaviour. typedef struct FT_Driver_Class_ { FT_Module_Class root; FT_Int face_object_size; FT_Int size_object_size; FT_Int slot_object_size; FTDriver_initFace init_face; FTDriver_doneFace done_face; FTDriver_initSize init_size; FTDriver_doneSize done_size; FTDriver_initGlyphSlot init_slot; FTDriver_doneGlyphSlot done_slot; FTDriver_setCharSizes set_char_sizes; FTDriver_setPixelSizes set_pixel_sizes; FTDriver_loadGlyph load_glyph; FTDriver_getCharIndex get_char_index; FTDriver_getKerning get_kerning; FTDriver_attachFile attach_file; FTDriver_getAdvances get_advances; } FT_Driver_Class; FT_END_HEADER #endif __FTDRIVER_H__ END
