title: Crop & Edit Images in C#
body: <p>I am looking to make a tool that allows me to basically edit images as you could in MS Paint. I can currently draw shapes and pens on my image but i don't know how to: 
   - Crop
   - Save New Image with Bitmap
   - Zoom in &amp; Out on Image
   - Stretch Image Out
   - Rotate the Image
  If anyone could help with any part of this question it would be most appreciated, and i have put this all in one question to stop me posting multiple similar questions. </p>
  
  <p>Thanks in Advance</p>
