This is * mainly used to support the compressed `*.pcf.bz2' fonts that come * with XFree86. * * @input: * stream :: * The target embedding stream. * * source :: * The source stream. * * @return: * FreeType error code. 0~means success. * * @note: * The source stream must be opened _before_ calling this function. * * Calling the internal function `FT_Stream_Close' on the new stream will * *not* call `FT_Stream_Close' on the source stream. 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 */
