Constructor Detail

Rectangle

public Rectangle(float x,
                 float y,
                 float x2,
                 float y2)

Creates a new Rectangle with the given coordinates. Note that the coordinates are assigned such that lx <= rx and by <= ty. So, e.g. x2 could be assigned to rx() or lx().
