Class TransformedShape

java.lang.Object
  java.awt.geom.AffineTransform
      org.geotools.renderer.j2d.TransformedShape

All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable, java.awt.Shape

public final class TransformedShape

extends java.awt.geom.AffineTransform

implements java.awt.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.
