Class TransformedShape

Object
  extended by AffineTransform
      extended by 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.
