Class MagnifyShapeTransformer

java.lang.Object

edu.uci.ics.jung.visualization.transform.MutableTransformerDecorator

edu.uci.ics.jung.visualization.transform.LensTransformer

edu.uci.ics.jung.visualization.transform.MagnifyTransformer

edu.uci.ics.jung.visualization.transform.shape.MagnifyShapeTransformer

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.

Constructors

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

Shape	inverseTransform(Shape shape)	Returns the supplied shape, translated to the coordinates that result from calling inverseTransform on its center.
Shape	magnify(Shape shape)	Magnify the shape, without considering the Lens.
Shape	magnify(Shape shape, float flatness)
Shape	transform(Shape shape)	Transform the supplied shape with the overridden transform method so that the shape is distorted by the magnify transform.
Shape	transform(Shape shape, float flatness)	map a shape from graph coordinate system to the screen coordinate system

Constructor Details

MagnifyShapeTransformer

public MagnifyShapeTransformer(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 used for rendering

MagnifyShapeTransformer

public MagnifyShapeTransformer(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 used for rendering

delegate - the transformer to use

Method Details

transform

public Shape transform(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 ShapeTransformer

Overrides:

transform in class LensTransformer

Parameters:

shape - a shape to transform

Returns:

a GeneralPath for the transformed shape

transform

public Shape transform(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 Shape inverseTransform(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

_transform

private Point2D _transform(Point2D graphPoint)

_inverseTransform

private Point2D _inverseTransform(Point2D viewPoint)

override base class to un-project the fisheye effect

magnify

public Shape magnify(Shape shape)

Magnify the shape, without considering the Lens.

Parameters:

shape - the shape to magnify

Returns:

the transformed shape
