Orthophoto basics WAS: [Mapserver-users] Raster geotiff turns background yellow

[Dylan Keon]

Hi Charlton,

I would recommend using a newer version of GD...it's up to 2.0.15 now. 
I think there were some problems with earlier versions (< 2.0.10?) of GD 
that have been cleared up in the newer versions.  Don't know if that's 
related to your issue, but it's worth doing anyway.

Your OUTPUTFORMAT block looks ok to me.  For more examples/info, see the 
Wiki page: http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?OutputFormat
