Ann, I am assuming that the nested lists are rgb triplets and that you are
referring to a 90 degree rotation using transpose. If so, for a discussion
how to rotate by some arbitrary angle go to
http://www.usm.maine.edu/~mjkcc/docs/ele489/labs/index.htm and download
Notebook 6: Geometric Operations.

Hope that helps, Mariusz

Do you mean


I would like to rotate the image by non-specific intervals.  Does anyone
know how I can do this with the standard package.
