Color (Java 2 Platform SE v1.4.1)

All Implemented Interfaces:
Paint, Serializable, Transparency

Direct Known Subclasses:
ColorUIResource, SystemColor

public class Color
extends Object
implements Paint, Serializable

The Color class is used encapsulate colors in the default sRGB color space or colors in arbitrary color spaces identified by a ColorSpace. Every color has an implicit alpha value of 1.0 or an explicit one provided in the constructor. The alpha value defines the transparency of a color and can be represented by a float value in the range 0.0 - 1.0 or 0 - 255. An alpha value of 1.0 or 255 means that the color is completely opaque and an alpha value of 0 or 0.0 means that the color is completely transparent. When constructing a Color with an explicit alpha or getting the color/alpha components of a Color, the color components are never premultiplied by the alpha component.
The default color space for the Java 2D(tm) API is sRGB, a proposed standard RGB color space. For further information on sRGB, see http://www.w3.org/pub/WWW/Graphics/Color/sRGB.html .

                           float saturation,
                           float brightness)
Converts the components of a color, as specified by the HSB model, to an equivalent set of values for the default RGB model.
The saturation and brightness components should be floating-point values between zero and one (numbers in the range 0.0-1.0). The hue component can be any floating-point number. The floor of this number is subtracted from it to create a fraction between 0 and 1. This fractional number is then multiplied by 360 to produce the hue angle in the HSB color model.
The integer that is returned by HSBtoRGB encodes the value of a color in bits 0-23 of an integer value that is the same format used by the method getRGB. This integer can be supplied as an argument to the Color constructor that takes a single integer argument.

Parameters:
hue - the hue component of the color
saturation - the saturation of the color
brightness - the brightness of the color
Returns:
the RGB value of the color with the indicated hue, saturation, and brightness.

                               float[] hsbvals)
Converts the components of a color, as specified by the default RGB model, to an equivalent set of values for hue, saturation, and brightness that are the three components of the HSB model.
If the hsbvals argument is null, then a new array is allocated to return the result. Otherwise, the method returns the array hsbvals, with the values put into that array.

Parameters:
r - the red component of the color
g - the green component of the color
b - the blue component of the color
hsbvals - the array used to return the three HSB values, or null
Returns:
an array of three elements containing the hue, saturation, and brightness (in that order), of the color with the indicated red, green, and blue components.

                                float b)
Creates a Color object based on the specified values for the HSB color model.
The s and b components should be floating-point values between zero and one (numbers in the range 0.0-1.0). The h component can be any floating-point number. The floor of this number is subtracted from it to create a fraction between 0 and 1. This fractional number is then multiplied by 360 to produce the hue angle in the HSB color model.
