[mapserver-users] grayscale shaded relief in mapserver

[Guillaume Sueur]

the main projection is the same. Extents are ok, the tif being much 
wider than the rest of the dataset. I'm explicitly calling it, and it 
returns a white image. shp2img on this specific layer does the same.
The raster values range from 0 to 255, but on my particuliar mapping 
zone, the are few differences between pixel values. I'm using GIF PC256 
for output.
