Constructor Detail

HSBColor

public HSBColor(Color rgbcolor)

Creates an instance transformed from the rgb color.

Parameters:

rgbcolor - standard java rgb color.

Method Detail

rgbToHSB

public static HSBColor rgbToHSB(Color color)

Inspired by float[] java.awt.Color.RGBtoHSB(int r,int g, int b, float[]hsbvals) except that algorithm is tuned
Testing results showed about 25% speed up. Therefore the sources have become harder to understand.

Parameters:

color - the java.awt.Color (that follows the RGB model) and should be transformed to a color instance in the hue-saturation-luminance model.

Returns:

the transformed values of the RGB colors in that order: hue,saturation,brightness.

clone

public Object clone()

Clone implementation.

Following statements are true:
x.clone() != x x.clone().getClass() == x.getClass() x.clone().equals(x) A deep copy of this HSBColor is returned.

Overrides:

clone in class Object

Returns:

an intance copied from this one.

equals

public boolean equals(Object o)

Equals implementation.

Returns true if :
o.instanceof HSBColor && (this.hue==o.hue) && (this.sat == o.sat) && (this.lum == o.lum)

Overrides:

equals in class Object

Parameters:

o - the other HSBColor instance.

Returns:

true if the colors are judged equal.

getRGBColor

public Color getRGBColor()

Returns the transformation of this color to the rgb color.

Returns:

the transformation of this color to the rgb color.

hashCode

public int hashCode()

Overrides:

hashCode in class Object
