What 'format' are you passing in? 'image/png' probably defaults to 8 bit png, unless your outputformat has mimetype "image/png" in it. > After some review of the images, it looks like my "DRIVER > AGG/PNG" produces a 24 bit png file via CGI, but an 8 bit > png file via WMS.

I'll have to do some more digging... I don't think there is an AGG/PNG24 driver, so you don't need to do that. The important information here is: * What does your outputformat look like * What "format=" are you passing to WMS? Regards, -- Christopher Schmidt MetaCarta
