<p>Using the named colors will of course be restricted to the colors known by the
library. If some other colors are needed then they must be specified
manually.</p>
<p>The first variant uses the RGB values for the color, i.e. the Red, Green and Blue
component of a color. Each component is specified as an integer in the range [0,255]
and the triple is specified as an array.</p>
<p>For example:</p>
<p>
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
<p><code class="code">SetColor( array(255,255,255));</code></p>
</li><li class="listitem">
<p><code class="code">SetColor( array(0xff,0xff,0xff));</code></p>
</li><li class="listitem">
<p><code class="code">SetFillColor( array(0x44,0x54,0xa4));</code></p>
</li></ul></div><p>
</p>
<p>As usual a value of <code class="code">array(0,0,0)</code> specifies black and a value of
<code class="code">array(255,255,255)</code> specifies white.</p>
