<code>type TSimpleTextureFont = class(<a class="normal" href="CastleFonts.TCastleFont.html">TCastleFont</a>)</code></p>
<h2 class="description">Description</h2>
<p>
2D font using a texture to define character images with constant width and height.

<p>This class has some assumptions about how the font image looks like: the characters are drawn in ASCII order, starting from space, on an image. Derive your own descendants of <a class="normal" href="CastleFonts.TCastleFont.html">TCastleFont</a> to have more flexibility, see the implementation of this class &mdash; it is quite simple. Or use <a class="normal" href="CastleFonts.TTextureFont.html">TTextureFont</a> that can read data from a FreeType (like ttf) font file.

<p>See e.g. castle_game_engine/examples/fonts/data/sonic_asalga_0.png how to prepare an image for use with such font. You can find more such fonts on the Internet, see e.g. <a  href="http://opengameart.org/content/sonic-font">http://opengameart.org/content/sonic-font</a> and <a  href="http://opengameart.org/content/null-terminator">http://opengameart.org/content/null-terminator</a>.</p>
