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.

            // Retrieve the destination bounds.
            Rectangle dstBounds = op.getBounds();


            // If necessary, clip the warped ROI to the destination bounds.
            if(!dstBounds.contains(dstROI.getBounds())) {
                dstROI = dstROI.intersect(new ROIShape(dstBounds));
            }


            // Return the warped and possibly clipped ROI.
            return dstROI;
        } else {
