color mapping question [message #6806]

Hi all,

I have a 256 color grayscale image and i'd like to overlay a
coastline with some color (red). How would I strech the grayscale
data values to fit 0-254 and reserve value 255 for a certain rgb
color? I'm Not having much luck with STRETCH,0,254 and then assigning
a rgb color to 255.

Thanks,
Scott
