53 * @function:
54 * FT_Stream_OpenBzip2
55 *
56 * @description:
57 * Open a new stream to parse bzip2-compressed font files. This is
58 * mainly used to support the compressed `*.pcf.bz2' fonts that come
59 * with XFree86.
60 *
61 * @input:
62 * stream ::
63 * The target embedding stream.
64 *
65 * source ::
66 * The source stream.
67 *
68 * @return:
69 * FreeType error code. 0~means success.
70 *
71 * @note:
72 * The source stream must be opened _before_ calling this function.
73 *
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.
77 *
78 * The stream implementation is very basic and resets the decompression
79 * process each time seeking backwards is needed within the stream.
80 *
81 * In certain builds of the library, bzip2 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 bzip2 compressed stream
85 * from it and re-open the face with it.
86 *
87 * This function may return `FT_Err_Unimplemented_Feature' if your build
88 * of FreeType was not compiled with bzip2 support.
