<p>The source stream must be opened <i>before</i> calling this function.</p>
<p>Calling the internal function &lsquo;FT_Stream_Close&rsquo; on the new stream will <b>not</b> call &lsquo;FT_Stream_Close&rsquo; on the source stream. None of the stream objects will be released to the heap.</p>
<p>The stream implementation is very basic and resets the decompression process each time seeking backwards is needed within the stream.</p>
<p>In certain builds of the library, gzip compression recognition is automatically handled when calling <a href="ft2-base_interface.html#FT_New_Face">FT_New_Face</a> or <a href="ft2-base_interface.html#FT_Open_Face">FT_Open_Face</a>. 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.</p>
<p>This function may return &lsquo;FT_Err_Unimplemented_Feature&rsquo; if your build of FreeType was not compiled with zlib support.</p>
