I remember some linear algebra, if that might be helpful. The kind of stuff that's covered here: https://en.wikipedia.org/wiki/Transformation_matrix#Examples_in_2D_computer_graphics Though panning is a different beast. Panning implies losing some information and gaining other info, which is a different kettle of fish from scaling/shearing/reflection and similar operations. What is the problem you are tying to solve? -- Regards, Branden
