title: Auto sizing zoom on an image in .NET
body: <p>I'm considering a personal learning project. Using .NET(preferably VB) I want to build a simple desktop app that's only function is to display comics, like CDisplay, but with more advanced navigation. I want to be able zoom in by clicking on certain areas of an image, individual panels for instance, and have the zoom area automatically snap to the panel and blow it up. The images are usually in a standard format like .jpeg, .png, etc.. </p>
  
  <p>Something like this is what I'm going for: <a href="http://iphonecomicbookreader.com/" rel="nofollow noreferrer">http://iphonecomicbookreader.com/</a></p>
  
  <p>I'm not even sure what this is called? Image mapping? Tone mapping maybe? Is it possible to do this within .NET or would it require some kind of outside library? Code samples would be nice, but obviously this is pretty vague request. Just being pointed in the right direction would be really helpful. </p>
  
  <p>Thanks</p>
