  • Method Details

    • get

      public int get()
      Get the color value as a hex code. This is useful for comparing pixels.
      Returns:
      hex code

    • getHSB

      public double getHSB()
      Get the color value on the HSB spectrum.
      Returns:
      hue value [0...255]

    • setHSB

      public void setHSB(double h)
      Setting the color value after the HSB spectrum. Saturation and Luminosity are fixed at 255.
      Parameters:
      h - A hue value [0...255]

    • setHSB

      public void setHSB(double h, double s, double l)
      Setting the color value after the HSB spectrum.
      Parameters:
      h - A hue value [0...255]
      s - A saturation value [0...255]
      l - A luminosity value [0...255]

    • setRGB

      public void setRGB(double r, double g, double b)
