Frank, No the declarations are not nested, I just made a mistake while pasting it in the message.
I am trying to use a custom outputformat. I set something like: IMAGETYPE "custom" OUTPUTFORMAT NAME "custom" DRIVER "GD/PNG" MIMETYPE "image/png" IMAGEMODE RGB FORMATOPTION INTERLACE=OFF TRANSPARENT OFF END ...the resulting display is lower color quality than the first one and the image size is 53KB. I tried the same without the quotation marks, it is the same. Then I have tried different combinations using DRIVER "GDAL/PNG", nothing works...then I tried using IMAGETYPE png without having OUTPUTFORMAT png defined - the same. But when I replace both and set: IMAGETYPE png OUTPUTFORMAT NAME png DRIVER "GD/PNG" MIMETYPE "image/png" IMAGEMODE RGB FORMATOPTION INTERLACE=OFF TRANSPARENT OFF END ...the resulting display is better color quality and the image size is 303KB ! So I really don't understand what is happening. I am using MS4W. Mapserv.exe -v shows: MapServer version 4.10.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG The problem is that I don't know if the "better display result" is indeed the best one I can get...
