<p>This section contains the declaration of Bzip2-specific functions.</p>
<div class="section">
<h3 id="FT_Stream_OpenBzip2">FT_Stream_OpenBzip2</h3>
<p>Defined in FT_BZIP2_H (ftbzip2.h).</p>
<pre>
FT_EXPORT( <a href="ft2-basic_types.html#FT_Error">FT_Error</a> )
<b>FT_Stream_OpenBzip2</b>( <a href="ft2-system_interface.html#FT_Stream">FT_Stream</a> stream,
<a href="ft2-system_interface.html#FT_Stream">FT_Stream</a> source );
</pre>
<p>Open a new stream to parse bzip2-compressed font files. This is mainly used to support the compressed ‘*.pcf.bz2’ fonts that come with XFree86.</p>
<h4>input</h4>
<table class="fields">
<tr><td class="val" id="stream">stream</td><td class="desc">
<p>The target embedding stream.</p>
</td></tr>
<tr><td class="val" id="source">source</td><td class="desc">
<p>The source stream.</p>
</td></tr>
</table>
<h4>return</h4>
<p>FreeType error code. 0 means success.</p>
<h4>note</h4>
<p>The source stream must be opened <i>before</i> calling this function.</p>
<p>Calling the internal function ‘FT_Stream_Close’ on the new stream will <b>not</b> call ‘FT_Stream_Close’ 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, bzip2 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 bzip2 compressed stream from it and re-open the face with it.</p>
<p>This function may return ‘FT_Err_Unimplemented_Feature’ if your build of FreeType was not compiled with bzip2 support.</p>
