[mapserver-users] .img raster color expression

[Fuchs Juan Carlos]

Hi Derek

Try with this for each class you want (just change the expression value and
the color. Be carefull with upper/lower case ;)

CLASSITEM 'FORESTYPE '
  CLASS #attribute name, without # gives the label name for the reference
	EXPRESSION > 0 
    	COLOR 214 252 252
    	OUTLINECOLOR 0 0 0
  END

Cheers
JC

Asunto: [mapserver-users] .img raster color expression


Hello,
I originally posted this is dev, but I think it might be more inline with
the user forum.
I am working with a .img raster file.  It has It has attribute called
FORESTYPE as I can see it when I open it in a desktop GIS.  I would like
to key off of this value to define specific colors in a .map file.
However, I cannot seem to get this working.  Here is what I have:

CLASS
     NAME "test"
     EXPRESSION ([FORESTYPE]>  0)
     STYLE
         COLOR     255 255 255
     END
END

Any help would be greatly appreciated.

Thanks,
