[mapserver-users] Stretching subset of a raster

[Jeff McKenna]

Hi Asen,

What happens if you remove the PROCESSING line from your first test, 
save that image with a shp2img command, and then add PROCESSING 
"SCALE=10,20" and re-run shp2img?  The pixel values in the 10-20 range 
should be stretched in the second image, which you can compare to your 
first non-stretched image.

(if I am understanding your situation, ha)
