Class 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.
