title: CBitmap and CImage interchangeable?
body: <p>I'd like to know how something like this can be done </p>
  
  <pre><code>CBitmap bmp;  
  CImage img;
  
  ///
  
  bmp=img;  
  
  //use bmp here
  </code></pre>
  
  <p>In my program I have to use CBitmap at some point but from the start I am only around with CImage. </p>
