I have two newbie questions and would appreciate any help:
1. How would I write code that will import an RGB image file (TIFF or something simple), access individual pixels and change them &/or combine them in groups depending on their shade, color and surroundings, and then export the changed file so I can view it?
2. To do this, what might I need in addition to VB.NET and how would I combine what I need with VB.NET?
-- I don't want the user to do anything but call up the program, tell it what image file to work on, and view output.

The System.Drawing namespace has lots of things in it for image manipulation. I'm not sure what capabilities exist for pixel twiddling type tasks, but a little exploration within that namespace might yield your answer.
