I see. For doing that, you don't want VPython. It can render 3D images
constructed by code, writing the positions of boxes, spheres, lines
and so; but it cannot process images, at least as far as I know.
For processing images the best library I know is Matplotlib. Here is a
tutorial: http://matplotlib.sourceforge.net/users/image_tutorial.html.
It imports the image as a matrix, in which each element represents a
pixel, and it is, or a number from 0 (black) to 1 (white) , or a list
of three elements (RGB). Starting from that, you can work, well in a
more compact way treating it like matrices, or in a more elementary
way element by element.
As a footnote, Matplotlib works natively only with png, but if you
have PIL installed, it can open any other file exactly in the same
way.
Also, I am thinking in another way to work. GIMP is actually a GUI for
a tool that you could program to do what you want. I haven't tried it,
so I cannot tell you more.
I hope it helps.
