CWIMAQOverlay
CWIMAQOverlay contains methods that draw shapes onto the overlay. These shapes are displayed on top of a CWIMAQImage. Overlays do not modify the actual image pixels and are deleted when the image is resized. To save overlay information along with an image, use CWIMAQVision.WriteImageAndVisionInfo.
