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

        double w = v0.getWidth() +
            ((v1.getWidth() - v0.getWidth()) * fraction);
        double h = v0.getHeight() +
            ((v1.getHeight() - v0.getHeight()) * fraction);
        Dimension2D value = (Dimension2D)v0.clone();
        value.setSize(w, h);
        return value;
