[mapserver-users] Reclassify raster cell values

[Rahkonen Jukka]

Hi,

Perhaps you just do it somehow wrong. Show your PROCESSING line and try meanwhile something like

PROCESSING "LUT=0:255,1:1,255:255"

I haven't tried it myself, this is mostly a guess.

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

Hi,

It should be possible to do what you want by using the PROCESSING LUT option.
