Hello!

I have a bit of a problem and was hoping you could help me out.
I have a file in which I have n*m (integers, neither is bigger than 500) array of positive integers each representing a height at those coordinates in a map.
How can I generate image of that map? I tried to find a module for that but I found several modules for generating images but none of them really helps me.
All I could think of by myself was to manually generate plain .ppm format picture or even raw .ppm if that doesn't work.
Is there other way to do that? Some module from CPAN? I tried to find one, but ones I found don't help with my problem.
Also I have to edit that map later, so it would be nice if you can recommend a module for that also. :)
Thank You for Your time.

Best regards!
