Hi.
Here's a class with quite a few different functions to manipulate with images.
No credit to me, though. Christian Graus is the real author of these functions. I only ported it to VB.
I have re-written a few to take advantage of the ColorMatrix, but the hardcore functions like Swirl and Sphere and Water etc. are left intact.
The code is not commented, because I frankly have no idea what he's doing. I just changed to code and kept his formulas.
Have fun...
