<code class="function">SetPrintImage</code> determines whether or not to automatically
output the image (as if <a class="xref" href="PrintImage.html" title="PrintImage"><span class="refentrytitle">PrintImage</span></a> was used) when a plot
is drawn (with <a class="xref" href="DrawGraph.html" title="DrawGraph"><span class="refentrytitle">DrawGraph</span></a>).  The default is True.
    </p></div><div class="refsect1"><a id="idp1378720212"></a><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>$pi</code></em></span></dt><dd><p>
True to have DrawGraph automatically print (output) the image, False to
prevent DrawGraph from outputting the image.
          </p></dd></dl></div></div><div class="refsect1"><a id="idp1378721756"></a><h2>Notes</h2><p>
When putting multiple plots on one image, is is necessary to use
<code class="function">SetPrintImage(False)</code> to defer output of the image
until after all the plots have been drawn.
See <a class="xref" href="adv-multiplot.html" title="4.8. Multiple Plots Per Image">Section 4.8, &#8220;Multiple Plots Per Image&#8221;</a> for more information on putting
multiple plots on an image.
    </p><p>
Calling <code class="function">SetPrintImage(False)</code> is also needed when using
<a class="xref" href="EncodeImage.html" title="EncodeImage"><span class="refentrytitle">EncodeImage</span></a> to return the image data (rather than sending
it to standard output or to a file).
