      • computeCrossings

        public int computeCrossings​(int crossings,
                                    int x0,
                                    int y0,

                                    int y1)
        Compute the crossings between this shadow and the given segment.
        Parameters:
        crossings - is the initial value of the crossings.
        x0 - is the first point of the segment.
        y0 - is the first point of the segment.
        x1 - is the second point of the segment.
        y1 - is the second point of the segment.
        Returns:
        the crossings or GeomConstants.SHAPE_INTERSECTS.
