Class MagnifyShapeTransformer

java.lang.Object

org.jungrapht.visualization.transform.MutableTransformerDecorator

org.jungrapht.visualization.transform.LensTransformer

org.jungrapht.visualization.transform.MagnifyTransformer

org.jungrapht.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.
