[Mapserver-users] GTiff/RGB-Output resulting in yellow image

[Oliver Wesp]

Hi,

first of all thanks for your response. In fact I'm reprojecting the data so 
maybe this is the point. I'm using GD 2.0.12 now with the same effects as 
mentioned. I'm looking into getting a small project together and to submit 
a bug.

best regards
Oliver
