This is quite easy, but the answer will totally depend on what library you are using. System.Drawing is one things, WPF is another story (also will depend on which part of WPF you are using). Please provide more essential information, and you will get help real fast.

Please see my comment to the question and clarify accordingly. However, as it's most likely that you are talking about System.Drawing, this is what you would need:
