<h2 class="description">Description</h2>
<p>
2D font using a texture initialized from a FreeType font file.

<p>This can load a font file, or it can use ready data in <a class="normal" href="CastleTextureFontData.TTextureFontData.html">TTextureFontData</a>. The latter allows to use this for fonts embedded in a Pascal source code, since our texturefont2pascal can convert a font ttf to a unit that defines ready <a class="normal" href="CastleTextureFontData.TTextureFontData.html">TTextureFontData</a> instance.</p>
