All Implemented Interfaces:

BidirectionalTransformer, MutableTransformer, ShapeFlatnessTransformer, ShapeTransformer, ChangeEventSupport

public class HyperbolicShapeTransformer
extends HyperbolicTransformer
implements ShapeFlatnessTransformer

HyperbolicShapeTransformer extends HyperbolicTransformer and adds implementations for methods in ShapeFlatnessTransformer. It modifies the shapes (Vertex, Edge, and Arrowheads) so that they are distorted by the hyperbolic transformation

Constructor Summary

HyperbolicShapeTransformer(Component component)
Create an instance, setting values from the passed component and registering to listen for size changes on the component.

HyperbolicShapeTransformer(Component component, MutableTransformer delegate)
Create an instance, setting values from the passed component and registering to listen for size changes on the component, with a possibly shared transform delegate.

Method Summary

Shape	inverseTransform(Shape shape) return the supplied shape, translated to the coordinates that result from calling inverseTransform on its center
Shape	transform(Shape shape) Transform the supplied shape with the overridden transform method so that the shape is distorted by the hyperbolic transform.
Shape	transform(Shape shape, float flatness) map a shape from graph coordinate system to the screen coordinate system
