Examples of java.awt.geom.Rectangle2D.outcode()

java.awt.geom.Rectangle2D.outcode()
Determines where the specified coordinates lie with respect to this Rectangle2D. This method computes a binary OR of the appropriate mask values indicating, for each side of this Rectangle2D, whether or not the specified coordinates are on the same side of the edge as the rest of this Rectangle2D. @param x the specified X coordinate @param y the specified Y coordinate @return the logical OR of all appropriate out codes. @see #OUT_LEFT @see #OUT_TOP @see #OUT_RIGHT @see #OUT_BOTTOM @since 1.2
