Hello,

I`m struggling with an image processing problem. I want to load a image
data file and want to eliminate all colors expect a rgb value which I
choose and the background color. The following link should illustrate
what I want to do:

I have no problem with loading the image. Also I can read the rgb
triplet of each data pixel with the following command
envi_get_rgb_triplets, Data[i,j], r, g, b and I can compare them with
the choosen rgb value. My problem is how to change these rgb_triplets?
