50    <div class="section">
51      <p>Constructs a font from successive loads from the archive font.</p><p>In <span class="argument">stream</span>, specify a pointer to a portion of the archive font loaded into memory; in <span class="argument">streamSize</span>, specify the portion's size. As long as the portions of the specified archive font are in order from the beginning, there are no restrictions on partition size or cycles.</p><p>By using the <CODE><a href="../../../nw/font/ArchiveFont/InitStreamingConstruct.html">nw::font::ArchiveFont::InitStreamingConstruct</a></CODE> unction and the <CODE>StreamingConstruct </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 initialize the streaming construct context with the <CODE><a href="../../../nw/font/ArchiveFont/InitStreamingConstruct.html">nw::font::ArchiveFont::InitStreamingConstruct</a></CODE> function, then call the <CODE>StreamingConstruct</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/ArchiveFont/Construct.html">nw::font::ArchiveFont::Construct</a> </CODE>function.</p></div>
