<div class="textblock"><p>Implementation of the <a class="el" href="classCEGUI_1_1Font.html" title="Class that encapsulates a typeface.">Font</a> class interface using the FreeType library. </p>
<p>This implementation tries to provide maximal support for any kind of fonts supported by FreeType. It has been tested on outline font formats like TTF and PS as well as on bitmap font formats like PCF and FON.</p>
<p>Glyphs are rendered dynamically on demand, so a large font with lots of glyphs won't slow application startup time. </p>
