Overview
Demonstrates how to build an image mask and use it to mask out a portion of an image.
Description
The example allows the user to draw a region of interest and then mask out all pixels that aren't in that region. The masked image is displayed in a separate window and window events are used to ensure the same position and zoom factor between the two images.
