Hi, me again,

I was a bit too euphoric the first time.
I managed to correct the script image.m to get what I wanted (the beautiful
world of GPL) and I tried to post a correction of the script, but
was unsuccessful (in correcting, not attaching the script).

The improvement that I see should be made in the two commands
gset cbrange [0:64], to allow for any color range. If one has
a function that takes only values 1 and 0, the plot is just black.
How can one dynamically change the cbrange?

Alt 1: Multiply the function by 64.

Alt 2: Use imagesc (which auto scales the image and then calls image.m).
