<h1>GLFT_Font</h1>
|
||||
|
||||
<h2>About GLFT_Font</h2>
|
||||
<p>
|
||||
GLFT_Font is originally by <a href="mailto:jpt2433@rit.edu">James Turk</a>
|
||||
although it is based on the work of
|
||||
<a href="http://marijn.haverbeke.nl">Marijn Haverbeke</a>. GLFT_Font allows
|
||||
programmers to use fonts in their OpenGL applications with great ease on any
|
||||
platform for which both <a href="http://freetype.org">FreeType2</a> and
|
||||
<a href="http://opengl.org">OpenGL</a> are available.
|
||||
</p>
|
||||
|
||||
<h2>Obtaining GLFT_Font</h2>
|
||||
<p>
|
||||
The latest copy of GLFT_Font will be available via this website.
|
||||
At the moment the latest version is <a href="glftfont-0.1.tar.gz">0.1</a>.
|
||||
</p>
|
||||
|
||||
<h2>Using GLFT_Font</h2>
|
||||
<p>
|
||||
Using GLFT_Font is designed to be extremely simple. The simplest use is:
|
||||
<hr />
|
||||
<pre>
|
||||
#include "GLFT_Font.h"
|
||||
|
||||
...
|
||||
glEnable(GL_TEXTURE_2D);
|
||||
glEnable(GL_BLEND);
|
||||
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);
|
||||
...
|
||||
Font fnt("somefont.ttf", size);
|
||||
...
|
||||
fnt.drawText(x, y, "Hello World");
|
||||
</pre>
|
||||
<hr />
|
||||
GLFT_Font also includes support for finding the width/height of a string and
|
||||
drawText supports printf-style argument formatting.
|
||||
</p>
|
||||
|
||||
<h2>Changelog</h2>
|
||||

|
||||

|
||||
<li> <a href="glftfont-0.1.tar.gz">Version 0.1</a> - 1 July 2005 - Initial Release </li>
|
||||
