  <p>I'm writing a C# application, that opens an image, and clicking on a button, displays it in only black and white!
  I was sure to find a lot of information on the net, but my searches didn't give me a lot of understandable and useful information.</p>
  
  <p>I have no idea of how to proceed. Does any one have any advice ? Know a tutorial on the net?</p>
