Hi Steve, I am not sure what your use of IMAGECOLOR has to do here. Normally I have some layers in between the background and the elevation lines.
But there are two more ways do get the color to be transparent in Mapserver: STYLE GEOMTRANSFORM 'labelpoly' COLOR "#ffffff00" END or STYLE GEOMTRANSFORM 'labelpoly' COLOR 255 255 255 OPACITY 0 END But those are doing the same thing as your solution below with COLOR -1 -1 -1 Maybe You are after some of the potential techniques that Thomas talked about a couple of years ago with layer blending with the label cache. Those were some future techniques that could be added to the layer composite pipeline if anyone was interested.
