David,

Great! Thanks! I had to download your library to get some of the
functions of tvlct to work but it works great. Now, I might be
pushing my luck here, but each data area has a range of values as
well. Basically, I modeled a multispectral image array and the areas
I'm highlighting have results of my modeling. If I want to, can I
overlay a false colored tvscl image in a similar manner?

Thanks!
Josh
