<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I have been playing around with this and I have come up with something that works. A bit crude and could probably be improved, but the bottom line is that
you get a dynamic legend on the PDF maps.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Most of the coding is done by modifying the existing print.php. But first there’s a bit of setup work with the templates. Modify your map templates so that
you have an area to place the legend. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Next, you need to create images of each legend item. I simply took a screenshot of my GM application with all layers turned on, then in Paint.net, I created
an image for each layer’s legend. Save these to the application’s htdocs/images folder.<o:p></o:p></span></p>
