Examples of javax.media.jai.ROI.intersect()

javax.media.jai.ROI.intersect()
Intersects the ROI with another ROI and returns the result as a new ROI. The supplied ROI will be converted to a rendered form if necessary. The bounds of the resultant ROI will be the intersection of the bounds of the two ROIs being merged. @param roi An ROI. @throws IllegalArgumentException if roi is null. @return A new ROI containing the new ROI data.
