None of the stream * objects will be released to the heap. * * The stream implementation is very basic and resets the decompression * process each time seeking backwards is needed within the stream. * * In certain builds of the library, bzip2 compression recognition is * automatically handled when calling @FT_New_Face or @FT_Open_Face. * This means that if no font driver is capable of handling the raw * compressed file, the library will try to open a bzip2 compressed stream * from it and re-open the face with it. * * This function may return `FT_Err_Unimplemented_Feature' if your build * of FreeType was not compiled with bzip2 support. */ FT_EXPORT( FT_Error ) FT_Stream_OpenBzip2( FT_Stream stream, FT_Stream source ); /* */ FT_END_HEADER #endif /* __FTBZIP2_H__ */ /* END */
