58    <div class="section">
59      <p>Performs initialization to construct a font by extracting glyph groups successively loaded from the archive font.</p><p>For <span class="argument">bufferSize</span>, specify the buffer size that can be obtained with the <CODE><a href="../../../nw/font/PackedFont/GetRequireBufferSize.html">nw::font::PackedFont::GetRequireBufferSize</a></CODE>function.  For <span class="argument">pBuffer</span>, specify the pointer to a memory region of that buffer size. When the font is successfully constructed, the memory region pointed to by <CODE>pBuffer</CODE> is under the management of this instance. Do not overwrite or release this memory region until the <CODE><a href="../../../nw/font/PackedFont/Destroy.html">nw::font::PackedFont::Destroy</a></CODE> function is called. The cache count specified by the <CODE><a href="../../../nw/font/PackedFont/GetRequireBufferSize.html">nw::font::PackedFont::GetRequireBufferSize</a></CODE> function does not need to be specified here because it can be obtained internally by inverse calculating <CODE>bufferSize</CODE>. </p><p>See the description for the <CODE><a href="../../../nw/font/PackedFont/GetRequireBufferSize.html">nw::font::PackedFont::GetRequireBufferSize</a></CODE> function for the meaning of the value specified by <span class="argument">glyphGroups</a>.</p><p>By using the <CODE>InitStreamingConstruct</CODE> function and the <CODE><a href="../../../nw/font/PackedFont/StreamingConstruct.html">nw::font::PackedFont::StreamingConstruct</a></CODE> function as a pair, you can build a font from a DVD or NAND using only a small read buffer.   To construct the font, first use the <CODE>InitStreamingConstruct</CODE> function to initialize the streaming construct context, then call the <CODE><a href="../../../nw/font/PackedFont/StreamingConstruct.html">nw::font::PackedFont::StreamingConstruct</a> </CODE> function each time data is obtained from DVD or NAND. </p><p>If the entire archive font can be read into memory, you can use the simpler <CODE><a href="../../../nw/font/PackedFont/Construct.html">nw::font::PackedFont::Construct</a></CODE> function.</p></div>
