[mapserver-users] Legend Icon with Raster Layer

[Thomas Haechler]

hi all

I try to create a dynamic legend in mapscript with the
createLegendIcon() method. this works fine for point/line/polygon
layers, but raster layers don't appear in the legend at all. so I added
a class with just a name to that layer. the name is displayed properly,
but the icon is just white. I tried with a pixmap-symbol, but it only
gets drawn as a legend icon, if the color in the class object is set.
but unfortunately, this leads into another problem: the layer is drawn
in this color in the main map. the same also happens with the
drawLegend() method.

what am I missing, or is it not possible?
thanks,

thomy
