The mask region of interest specified by the maskROI pointer is discussed
in the section Image Regions of Interest (Chapter 2). The intersection of
aligned rectangular ROI(s) and maskROI(s) for all source images and the
destination image forms the actual region to be processed.
For geometric transformation functions, such as
Zoom() or Mirror(),the
shape and orientation of rectangular ROIs and mask ROIs of the source
image changes according to the function. In these cases, the functions write
the results of image processing to the intersection of the destination ROI
and the transformed source ROI.
For more information about geometric transformation, see Chapter 11.
Return Value
The newly constructed IplImage header.
