edu.rit.color.RGB

public class RGB
extends java.lang.Object

Class RGB provides a color represented as floating point red, green, and blue components.

Class RGB includes methods for packing and unpacking a floating point RGB color object into and from an integer. The packed color representation uses 8 bits for each component, with the red component in bits 23-16, the green component in bits 15-8, and the blue component in bits 7-0.
