Class MagnifyTransformer
java.lang.Object
edu.uci.ics.jung.visualization.transform.MutableTransformerDecorator
edu.uci.ics.jung.visualization.transform.LensTransformer
edu.uci.ics.jung.visualization.transform.MagnifyTransformer
- All Implemented Interfaces:
BidirectionalTransformer
,MutableTransformer
,ShapeTransformer
,ChangeEventSupport
- Direct Known Subclasses:
MagnifyShapeTransformer
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.
