Class Rect

java.lang.Object

net.richarddawkins.watchmaker.geom.impl.Rect

public class Rect
extends java.lang.Object

Java class to simulate a QuickDraw Rect (rectangle) In Pascal, a QuickDraw Rect is defined this way: TYPE RECT = RECORD (left, top, right, bottom: INTEGER); The bounding box calculations in Classic Watchmaker use a Pascal Rect record, which is defined by left, top, right, and bottom coordinates. This is at variance with the Java way of doing things, where Rectangles are defined by their upper left corner (x,y) and (width,height.) This class bridges the two.
