Class TransformedShape

Object

AffineTransform

TransformedShape

All Implemented Interfaces:

Shape, Serializable, Cloneable

public final class TransformedShape
extends AffineTransform
implements Shape

Apply an arbitrary AffineTransform on a Shape. This class is used internally by RenderedMarks. It is designed for reuse with many different affine transforms and shapes. This class is not thread-safe.
