Say, you can draw one image on another image. Locate one of the methods System.Drawing.Graphics.DrawImage, the one which "draws the specified portion of the specified Image at the specified location and with the specified size":

This way, you can create an image showing a copy of a required part of your original image. First, you need to create a target image of required size and obtain the instance of System.Drawing.Graphics using the method System.Drawing.Graphics.FromImage:
