getArrowHead

public static GeneralPath getArrowHead(Point p1,
                                       Point p2,
                                       int arrowBarbSize,
                                       double arrowPhi)

Returns a path for the arrow at the end of an edge from p1 to p2.

Parameters:

arrowBarbSize - gives the size of the barb in pixels (i.e. the size of the arrow tip)

arrowPhi - gives the angle between the barbs and the center line, i.e. this is half of the angle of the arrow tip.

getChopboxAnchor

public static Point getChopboxAnchor(Rectangle box,
                                     Point referencePoint)

The ChopboxAnchor's location is found by calculating the intersection of a line drawn from the center point of a box to a reference point and that box. Code borrowed from org.eclipse.draw2d.ChopboxAnchor.
