    • Constructor Detail

      • HSBColor

        public HSBColor​(java.awt.Color rgbcolor)
        Creates an instance transformed from the rgb color.

        Parameters:
        rgbcolor - standard java rgb color.

    • Method Detail

      • rgbToHSB

        public static HSBColor rgbToHSB​(java.awt.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 java.lang.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 java.lang.Object
        Returns:
        an instance copied from this one.

      • equals

        public boolean equals​(java.lang.Object obj)
        Overrides:
        equals in class java.lang.Object
        See Also:
        Object.equals(java.lang.Object)

      • getRGBColor

        public java.awt.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 java.lang.Object
