[mapserver-users] Reclassify raster cell values

[ALT SHN]

Thank you Rahknonen,

However this is not quite what I expected. If I reclassify a particular
value, all other cells disapear.
This leads me to another question (I'll open another topic too). the
PROCESSING LUT command can be used as a way to build a indexed color table
for 8bit rasters. Is there a way to import a color table ?

Thank you

André
