I have downloaded the DX8 Partial SDK for VB

The first tutorial I could probaly use for the zoom (although all it does is resize the picture to the form's size)

I need to do three things (ordered by priority)

1) Be able to replace a color instantly (like change all green pixels to red [I do mean exact RGB value])
2) Be able to zoom and pan an image (100%, 200%, etc)
3) be able to select a region to zoom in on (or just have that selected region look for now)

Any help is appreciated.
