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
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.
