title: Graphics.DrawImage darkened?
body: <p>I use the DrawImage Image function to copy a portion from an image to another.
  Is it possible to make it so the copied portion is "darker"? Like, a special color tone? Can someone give me an example? I heard of something called ImageAttributes but I can't find it!</p>
  
  <p>Note: I don't want to edit the source image.</p>
