[mapserver-users] FORMATOPTION "PALETTE_FORCE=TRUE" problem

[paalkr]

Hi!

I have tried to use the FORMATOPTION "PALETTE_FORCE=TRUE" with no luck. I've
goth this error message all the time:

My ouputformat is defined like this:

   OUTPUTFORMAT
      NAME "png8bit"
      DRIVER "AGG/PNG"
      MIMETYPE "image/png"
      EXTENSION "png"
      FORMATOPTION "PALETTE_FORCE=TRUE"
      FORMATOPTION "PALETTE=/opt/maps/kartdata2/mapfiles/palette.txt"
      FORMATOPTION INTERLACE=OFF
   END

The palette.txt file is attached
http://n2.nabble.com/file/n2117781/palette.txt palette.txt 

Does anyone know whats wrong?
BTW: This is MapServer 5.2.1 on RedHat.
