Class ArticulatedEdgeShapeFunctions

  • public class ArticulatedEdgeShapeFunctions
extends Object
    functions to convert a list of layout coordinate system points into a unit shape from 0,0 to 1,0. All edge shapes in jungrapht-visualization are transformed from the unit shape to the visualized shape during the visualization process

      • makeUnitShape

        public static Shape makeUnitShape​(List<Point> list)
        This is for articulated edge shapes that have intermediate articulation points. From the supplied list of points, make the 'unit' edge shape (0,0 to 1,0) by translating and scaling the incoming points to a Path2D from 0,0 to 1,0; This 'unit' shape will be transformed to the graph location during the visualization process
        Parameters:
        list - supplied points in layout coordinate system
        Returns:
        a Shape (Path2D) extending from 0,0 to 1,0

      • makeReverseUnitShape

        public static Shape makeReverseUnitShape​(List<Point> list)
        This is for articulated edge shapes that have intermediate articulation points. All feedback arcs (edges that were reversed in direction during the remove-cycles process) need to have their intermediate points modified so that when the edges are transformed into position, the articulation points are 'reversed' in cartesian space. From the supplied list of points, make the edge shape (0,0 to 1,0) as above, but if there are points between 0,0 and 1,0 flip those points vertically (y = -y) and move them horizontally (x = 1-x) so that the resulting shape articulation points are correct for the reversed edge direction.
        Parameters:
        list - supplied points in layout coordinate system
        Returns:
        a Shape (Path2D) extending from 0,0 to 1,0
