      • getSubbandRectROIMask

        public SubbandROIMask getSubbandRectROIMask​(int x,
                                            int y)
        Returns a reference to the Subband mask element to which the specified point belongs. The specified point must be inside this (i.e. the one defined by this object) subband mask. This method searches through the tree.
        Parameters:
        x - horizontal coordinate of the specified point.
        y - horizontal coordinate of the specified point.
