46    <div class="section">
47      <p>Gets glyph data.</p><p>With the <CODE>PackedFont</CODE> class, sheets in the font resource are maintained in a compressed state. They are expanded and cached when they are requested with the <CODE>GetGlyph</CODE> function. When it is necessary to cache a sheet after the cache reaches capacity, the last used sheet is deleted from the cache.<br /> The glyphs obtained with the <CODE>GetGlyph</CODE> function are not always valid, given this mechanism. The glyphs obtained with the <CODE>GetGlyph</CODE> function are guaranteed to be valid only until the next call to the <CODE>GetGlyph</CODE> function or until a cache management member function is called.</p></div>
