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, gzip compression recognition is * automatic 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 gzip stream from it and re-open * the face with it. * * this function may return "FT_Err_Unimplemented" if your build of * FreeType was not compiled with zlib support. */ FT_EXPORT( FT_Error ) FT_Stream_OpenGzip( FT_Stream stream, FT_Stream source ); /* */ FT_END_HEADER #endif /* __FTXF86_H__ */
