digitizerRect

Contains a pointer to a rectangle that is to receive the size and location information for the current digitizer rectangle.

The video digitizer component returns spatial information that is relative to the maximum source rectangle. For a complete discussion of the relationship between these rectangles, see "About Video Digitizer Components," which begins on page 8-3.
