public class RGB
extends 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.

Field Summary

float	blue The blue component in the range 0.0 through 1.0.
float	green The green component in the range 0.0 through 1.0.
float	red The red component in the range 0.0 through 1.0.

Constructor Summary

RGB()
Construct a new floating point RGB color.

RGB(float red, float green, float blue)
Construct a new floating point RGB color with the given red, green, and blue components.

RGB(int color)
Construct a new floating point RGB color from the given packed color.

Method Summary

int	pack() Pack this floating point RGB color into a packed color.
static int	pack(float red, float green, float blue) Pack the given red, green, and blue components into a packed color.
void	unpack(int color) Unpack this floating point RGB color from a packed color.
