Res: Re: [UMN_MAPSERVER-USERS] PC256 color images (I need more quality)

I guess I still don't know what your problem is.  If you're talking about 
quality in the sense of having compression artifacts, then you can add 
something like FORMATOPTION "QUALITY=100" in your OUTPUTFORMAT.  Or perhaps 
you should be using PNG24 instead of JPEG.   Read through 
http://mapserver.gis.umn.edu/doc/mapfile-reference.html#outputformat for more 
output related info.  

Also read  http://mapserver.gis.umn.edu/doc/raster-howto.html for raster input 
stuff.
