The GetMap request was using: format=image/png
...instead of format=image/png; mode=8bit Now I'm getting paletted 8-bit images instead of 24-bit RGB's.

You're right about the copying. It seems most image viewers will assume PNGs are RGB when copying an image from a browser. I had to use PIL in Python to show which WMS output images were 8-bit (mode = 'P') and 24-bit (mode='RGB'). Also, I think we still need the OUTPUTFORMAT section in our mapfiles since we're trying to use RGBA instead of RGB, which the built-in png8 output format uses. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/MapServer-6-WMS-output-to-8-bit-PNG-tp6626959p6627769.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
