Hey everyone,

I'm having an issue with the legend image for my heat map layers not displaying 
correctly when I specify a DPI through the LEGEND_OPTIONS.

My request:

http://transbasesf.org/geoserver/transbase_v1/ows?TRANSPARENT=TRUE&VIEWPARAMS=timed%3AA&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&EXCEPTIONS=application%2Fvnd.ogc.se_xml&LAYER=vw_geoserver_switrs_col_time&STYLE=Heatmap&FORMAT=image%2Fpng&LEGEND_OPTIONS=fontName%3AGill%20Sans%20MT%3BfontSize%3A8%3Bdpi%3A660%3BfontAntiAliasing%3Atrue%3B%22

Geoserver's response:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ServiceExceptionReport SYSTEM 
"http://transbasesf.org/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";>
<ServiceExceptionReport version="1.1.1">
   <ServiceException>java.lang.IllegalStateException: It is not legal to have a 
RasterSymbolizer here
It is not legal to have a RasterSymbolizer here</ServiceException>
</ServiceExceptionReport>
If I remove DPI from my LEGEND_OPTIONS request Geoserver returns the correct 
legend icon:

Is this a bug or is it just not possible to specify a DPI with a raster layer?

Thanks,
