I have been checking the forum for ideas and suggestions on
how to implement an interactive zoom and pan on an image. I would
like the user to be able to drag a "magnifing glass" or a circle
over an image, and then zoom in (or out) on the area in the
magnifing glass, using the mouse wheel. How might I go about
creating this effect? Or, the easier way, steal someone's code who
has implemented this kind of functionality.
