I want to grab some portion of image, do something to it, and save it to a file.  In this example, I grab a portion of an image and save it to a file but the image in the file is corrupted.  Evidently I'm doing something wrong.  I've spent a number of hours trying to figure it out, but I'm blind to the problem.  I would be very grateful for any help someone can give me.
