Examples of java.awt.geom.Dimension2D

java.awt.geom.Dimension2D
The Dimension2D class is to encapsulate a width and a height dimension.
This class is only the abstract superclass for all objects that store a 2D dimension. The actual storage representation of the sizes is left to the subclass. @version 1.15, 02/24/06 @author Jim Graham @since 1.2
