title: Extract a portion of an image in .NET
body: <p>I have a PNG of a deck of cards as 1 image (it has all 52 cards combined into 1 image file).  How do I extract an individual card out as I need it (or extract them all into separate image files at start up).</p>
  
  <p>I understand the logic of know which row and column to get, its the actual image manipulation code I am having trouble with.</p>
  
  <p>I am using Visual Studio 2010 and using VB (although sample code in any .NET language would do).</p>
  
  <p>I am not allowed to post the image itself, but here is an example image</p>
