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

All Implemented Interfaces:: BidirectionalTransformer, MutableTransformer, ShapeTransformer, ChangeEventSupport

Direct Known Subclasses:: MagnifyShapeTransformer

public class MagnifyTransformer extends LensTransformer implements MutableTransformer

MagnifyTransformer wraps a MutableAffineTransformer and modifies the transform and inverseTransform methods so that they create an enlarging projection of the graph points. MagnifyTransformer uses an affine transform to cause translation, scaling, rotation, and shearing while applying a separate magnification filter in its transform and inverseTransform methods.
