How to Improve WMS Image Quality? - SOLVED!

[Bill Thoen]

David,

I think my biggest problem at this point in learning MapSever is not 
knowing how things go together as the MapServer documentation is a bit 
spotty and scattered. But you gave me the clue and by guessing I 
eventually hit on defining an OUTPUTFORMAT object for gif images with 
IMAGEMODE set to RGB instead of PC256. Now it looks good -- Thanks!

   OUTPUTFORMAT
      NAME gif
      DRIVER "GD/GIF"
      MIMETYPE "image/gif"
      IMAGEMODE RGB
      EXTENSION "gif"
   END
