[mapserver-users] Trouble coloring a raster

[Brent Fraser]

Bob,
     I'd recommend just re-rendering the raster off-line for performance 
reasons, but if data management makes that difficult have a look at the  
"Classifying Rasters" section of 
http://www.mapserver.org/input/raster.html#how-are-rasters-added-to-a-map-file. 
And Mapserver can only classify a single 8-bit  band (grey or paletted), 
even if your image is say 3 band RGB.

Best Regards,
Brent Fraser
