|
||
<p>In addition to the predefined fonts it is possible to easily use up to three
|
||
custom fonts. This is done by first specifying the name of the font file that should
|
||
be used and then specifying the font family as either <code class="code">FF_USERFONT1</code>,
|
||
<code class="code">FF_USERFONT2</code> or <code class="code">FF_USERFONT3</code>. A new font is installed
|
||
by calling one or more of the methods</p>
|
||
<p>
|
||
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
|
||
<p><code class="code">Graph::SetUserFont1($aNormal,$aBold,$aItalic,$aBoldIt)</code>
|
||
(or the synonym <code class="code">SetUserFont()</code> )</p>
|
||
</li><li class="listitem">
|
||
<p><code class="code">Graph::SetUserFont2($aNormal,$aBold,$aItalic,$aBoldIt)</code></p>
|
||
</li><li class="listitem">
|
||
<p><code class="code">Graph::SetUserFont3($aNormal,$aBold,$aItalic,$aBoldIt)</code></p>
|
||
</li></ul></div><p>
|
||
</p>
|
||
<p>The argument to these methods should be the full font file name (including full
|
||
path) for the normal, bold, italic and/or bolditalic variant of the font family. All
|
||
arguments apart from "<code class="code">$aNormal</code>" are optional. </p>
|
||
<p>An example on how this can be used to use a special font for the title of a graph
|
||
is shown in
