* @function:
|
|
* FT_Stream_OpenGzip
|
|
*
|
|
* @description:
|
|
* Open a new stream to parse gzip-compressed font files. This is
|
|
* mainly used to support the compressed *.pcf.gz 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, gzip 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 gzipped 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.
