57
* Open a new stream to parse gzip-compressed font files. This is
58
* mainly used to support the compressed `*.pcf.gz' fonts that come
63
* The target embedding stream.
69
* FreeType error code. 0~means success.
72
* The source stream must be opened _before_ calling this function.
74
* Calling the internal function `FT_Stream_Close' on the new stream will
75
* *not* call `FT_Stream_Close' on the source stream. None of the stream
76
* objects will be released to the heap.
78
* The stream implementation is very basic and resets the decompression
79
* process each time seeking backwards is needed within the stream.
81
* In certain builds of the library, gzip compression recognition is
82
* automatically handled when calling @FT_New_Face or @FT_Open_Face.
83
* This means that if no font driver is capable of handling the raw
84
* compressed file, the library will try to open a gzipped stream from
85
* it and re-open the face with it.
87
* This function may return `FT_Err_Unimplemented_Feature' if your build
88
* of FreeType was not compiled with zlib support.
