New Revision: 2798

Modified:
   trunk/widgets/QuickPlot/PlotAsPDF.php
Log:
#584: Fix legend output for non-96 DPI plots. Due to http://trac.osgeo.org/mapguide/ticket/71, the legend element will always have to be at 96 DPI for the moment and thus our offsets and legend image requests should always be based around this assumption.
