Zooming and panning an image canvas

Question

I have a silverlight Canvas which holds an image with drawings on it (polygons). I need to develop a control to zoom and pan this canvas within a work area (Border within a Grid cell, as of now) as shown below. What is the best way to do this. Is there any libraries I can make use of?

I need to be able to add drawings to the zoomed/panned canvas too.

Lots of code examples available on the internet. Check out ZoomControl and CodePlex.
