[mapserver-users] How ro get transparent image on 6.0.1

[thomas bonfort]

Either your asp page is selecting the wrong (i.e. a non-transparent)
imagetype, or you have a layer that is drawn ontop of the transparent
background, thus making the final image non transparent. The
outputformat you have shown is correct and produces trasnparent
images.
