Hi Thomas! Unfortunately I it does not work like you described in my situation. 1) A palette file with only r,g,b values does not work, regardless of imagemode "rgb" or imagemode "rgba". It should have worked with imagemode "rgb" (or am I wrong?) 2)Imagemode "rgb" produces transparent pictures (which should not happen if I understood you correct) if the WMS parameter transparent=true. This is with quantize_force=on and quantize_colors=256 is set, or no color reduction at all. 3)Palette_force=true with palette file and the WMS transparent=true parameter produces an image where nodata areas is filled with blacks, regardless of imagemode "rgb" or imagemode "rgba" Regards, Pål Kristensen -- View this message in context: http://n2.nabble.com/FORMATOPTION-%22PALETTE_FORCE%3DTRUE%22-problem-tp2117781p2122929.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
