Class IltBoundingBox

java.lang.Object

ilog.tgo.grprim.IltBoundingBox

public class IltBoundingBox
extends Object

This class contains some primitive utility functions for determining the bounding box of the drawings produced by the drawing primitives.

They return a freshly allocated, integer-valued rectangle. Only the pixels with coordinates >= x, < x+width, >= y, < y+height will be covered by the corresponding drawing primitive. The return value can be null if the drawing is empty.
