Retrieves the FT_Face & FT_Size objects that correspond to a given FTC_SizeID.
Input:
manager :: A handle to the cache manager.
size_id :: The ID of the `font size' to use.
Output:
aface :: A pointer to the handle of the face object. Set it to zero if you don't need it.
asize :: A pointer to the handle of the size object. Set it to zero if you don't need it. Retrieves the FT_Face & FT_Size objects that correspond to a given FTC_SizeID.
Input:
manager :: A handle to the cache manager.
size_id :: The ID of the `font size' to use.
Output:
aface :: A pointer to the handle of the face object. Set it to zero if you don't need it.
asize :: A pointer to the handle of the size object. Set it to zero if you don't need it.
Notes: The returned FT_Face object is always owned by the manager. You should never try to discard it yourself. Never change the face's transformation matrix (i.e., never call the FT_Set_Transform() function) on a returned face! If you need to transform glyphs, do it yourself after glyph loading. Similarly, the returned FT_Size object is always owned by the manager. You should never try to discard it, and never change its settings with FT_Set_Pixel_Sizes() or FT_Set_Char_Size()! The returned size object is the face's current size, which means that you can call FT_Load_Glyph() with the face if you need to. FT_EXPORT( FT_Error ) FTC_Manager_Lookup_Size( FTC_Manager manager, FTC_Font font, FT_Face *aface, FT_Size *asize ); a cache class is used to describe a unique cache type to the manager typedef struct FTC_Cache_Class_ FTC_Cache_Class; typedef struct FTC_CacheRec_* FTC_Cache; this must be used internally for the moment FT_EXPORT( FT_Error ) FTC_Manager_Register_Cache( FTC_Manager manager, FTC_Cache_Class* clazz, FTC_Cache *acache ); FT_END_HEADER #endif __FTCACHE_H__ END
