Betreff: [mapserver-users] ArcSDE raster and value difference of 256

Hi list,

I am trying to use an ArcSDE raster layer in Mapserver, but the values
that Mapserver gives back are different from the values that ArcMap gives
back.

There is a difference of exactly 256.

So NODATA is 256 according to ArcMap, but Mapserver seems to map it to 0,
etc. for all other values.

Does anyone know how to solve this? TIA.
