This program allows the user to open any image and select or crop a rectangular portion of that image. May require the image-processing toolbox.
Updated from uiGetImageFile to imgetfile. This allows the user to use built-in functions to open an image file.
Corrected the message flag. Made sure that the message does not appear again if the user select the corners correctly the second time.
