Using SLD with GetLegendGraphic

[Michael Schulz]

Hi,

yes, mapserver will use the sld also for the legendgraphic. It is 
however important that you have a class name defined for the layer to 
return a legendgraphic. Some minimal legend configuration should also be 
present in the mapfile.

HTH, Michael
