Class Color4b

java.lang.Object

org.jogamp.vecmath.Tuple4b

org.jogamp.vecmath.Color4b

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class Color4b
extends Tuple4b
implements java.io.Serializable

A four-byte color value represented by byte x, y, z, and w values. The x, y, z, and w values represent the red, green, blue, and alpha values, respectively.

Note that Java defines a byte as a signed integer in the range [-128, 127]. However, colors are more typically represented by values in the range [0, 255]. Java 3D recognizes this and for color treats the bytes as if the range were [0, 255]---in other words, as if the bytes were unsigned.

Java 3D assumes that a linear (gamma-corrected) visual is used for all colors.

Constructor Detail

Color4b

public Color4b(byte b1,
               byte b2,
               byte b3,
               byte b4)

Constructs and initializes a Color4b from the four specified values.

Parameters:

b1 - the red color value

b2 - the green color value

b3 - the blue color value

b4 - the alpha value

Color4b

public Color4b(byte[] c)

Constructs and initializes a Color4b from the array of length 4.

Parameters:

c - the array of length 4 containing r, g, b, and alpha in order

Color4b

public Color4b(Color4b c1)

Constructs and initializes a Color4b from the specified Color4b.

Parameters:

c1 - the Color4b containing the initialization r,g,b,a data

Color4b

public Color4b(Tuple4b t1)

Constructs and initializes a Color4b from the specified Tuple4b.

Parameters:

t1 - the Tuple4b containing the initialization r,g,b,a data

Color4b

public Color4b(java.awt.Color color)

Constructs and initializes a Color4b from the specified AWT Color object. No conversion is done on the color to compensate for gamma correction.

Parameters:

color - the AWT color with which to initialize this Color4b object

Since:

vecmath 1.2

Color4b

public Color4b()

Constructs and initializes a Color4b to (0,0,0,0).

Method Detail

set

public final void set(java.awt.Color color)

Sets the r,g,b,a values of this Color4b object to those of the specified AWT Color object. No conversion is done on the color to compensate for gamma correction.

Parameters:

color - the AWT color to copy into this Color4b object

Since:

vecmath 1.2

get

public final java.awt.Color get()

Returns a new AWT color object initialized with the r,g,b,a values of this Color4b object.

Returns:

a new AWT Color object

Since:

vecmath 1.2
