Examples of AffineTransform2D

org.geotools.referencing.operation.transform.AffineTransform2D
Transforms two-dimensional coordinate points using an affine transform. This class both extends {@link AffineTransform} and implements {@link MathTransform2D}, so it can be used as a bridge between Java2D and the referencing module. @since 2.5 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD)
