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

Constructors

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

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

Constructor Detail

HyperbolicShapeTransformer

public HyperbolicShapeTransformer(java.awt.Component component)

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

Parameters:

component - the component in which rendering takes place

HyperbolicShapeTransformer

public HyperbolicShapeTransformer(java.awt.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.

Parameters:

component - the component in which rendering takes place

delegate - the transformer to use

Method Detail

transform

public java.awt.Shape transform(java.awt.Shape shape)

Transform the supplied shape with the overridden transform method so that the shape is distorted by the hyperbolic transform.

Specified by:

transform in interface ShapeTransformer

Overrides:

transform in class LensTransformer

Parameters:

shape - a shape to transform

Returns:

a GeneralPath for the transformed shape

transform

public java.awt.Shape transform(java.awt.Shape shape,
                                float flatness)

Description copied from interface: ShapeFlatnessTransformer

map a shape from graph coordinate system to the screen coordinate system

Specified by:

transform in interface ShapeFlatnessTransformer

Parameters:

shape - the shape to be transformed

flatness - used to break the supplied shape into segments

Returns:

a GeneralPath (Shape) representing the screen points of the shape

inverseTransform

public java.awt.Shape inverseTransform(java.awt.Shape shape)

Description copied from class: LensTransformer

Returns the supplied shape, translated to the coordinates that result from calling inverseTransform on its center.

Specified by:

inverseTransform in interface ShapeTransformer

Overrides:

inverseTransform in class LensTransformer
