All Implemented Interfaces:

BidirectionalTransformer, MutableTransformer, ShapeFlatnessTransformer, ShapeTransformer, ChangeEventSupport

public class MagnifyShapeTransformer
extends MagnifyTransformer
implements ShapeFlatnessTransformer

MagnifyShapeTransformer extends MagnifyTransformer and adds implementations for methods in ShapeTransformer. It modifies the shapes (Vertex, Edge, and Arrowheads) so that they are enlarged by the magnify transformation

Constructor Summary

Constructors

Constructor	Description
MagnifyShapeTransformer(java.awt.Component component)	Create an instance, setting values from the passed component and registering to listen for size changes on the component.
MagnifyShapeTransformer(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	Description
java.awt.Shape	inverseTransform(java.awt.Shape shape)	return the supplied shape, translated to the coordinates that result from calling inverseTransform on its center
java.awt.Shape	magnify(java.awt.Shape shape)	magnify the shape, without considering the Lens
java.awt.Shape	magnify(java.awt.Shape shape, float flatness)
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 magnify transform.
java.awt.Shape	transform(java.awt.Shape shape, float flatness)	map a shape from graph coordinate system to the screen coordinate system

MagnifyShapeTransformer

public MagnifyShapeTransformer(java.awt.Component component)

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

MagnifyShapeTransformer

public MagnifyShapeTransformer(java.awt.Component component,
                               MutableTransformer delegate)

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 magnify transform.

Specified by:

transform in interface BidirectionalTransformer

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

Description copied from interface: ShapeFlatnessTransformer

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

Specified by:

transform in interface ShapeFlatnessTransformer

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

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

Specified by:

inverseTransform in interface BidirectionalTransformer

Specified by:

inverseTransform in interface ShapeTransformer

Overrides:

inverseTransform in class LensTransformer

Returns:

magnify

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