Hi group,

can anyone out there tell me how to generate a color bitmap image
using MMA v 3.0.

I am trying to take a color image and run it through a 2 x 2 
Asinov Automorphism (i.e., a 2 x 2 linear transformation).  After
n iterations of this matrix, one will see the image split up and
then recompile into the original image.

I saw a picture of a Cat Map that was read as list of points.

How does one do this?

Thank you and have a happy and safe holiday to all.
