Examples of java.awt.geom.Area.transform()

java.awt.geom.Area.transform()
Transforms the geometry of this Area using the specified {@link AffineTransform}. The geometry is transformed in place, which permanently changes the enclosed area defined by this object. @param t the transformation used to transform the area @throws NullPointerException if t is null @since 1.2
