Class Color

  • java.lang.Object
    • java.awt.Color
  • All Implemented Interfaces:
    Paint, Transparency, java.io.Serializable
    Direct Known Subclasses:
    SystemColor
    public class Color extends java.lang.Object implements Paint, java.io.Serializable
    The Color class is used to 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 .

      Ordinary member indicator getHSBColor Reveal DetailHide Detail
      static Color getHSBColor(float h, float s, float b)
      Creates a Color object based on the specified values for the HSB color model.
      public static Color getHSBColor(float h, float s, 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.

      Parameters:
      h - the hue component
      s - the saturation of the color
      b - the brightness of the color
      Returns:
      a Color object with the specified hue, saturation, and brightness.

      Ordinary member indicator HSBtoRGB Reveal DetailHide Detail
      static int HSBtoRGB(float hue, 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.
      public static int HSBtoRGB(float hue, 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.

      Ordinary member indicator RGBtoHSB Reveal DetailHide Detail
      static float[] RGBtoHSB(int r, int g, int b, 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.
      public static float[] RGBtoHSB(int r, int g, int b, 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.

      Ordinary member indicator brighter Reveal DetailHide Detail
      Color brighter()
      Creates a new Color that is a brighter version of this Color.
      public Color brighter()
      Creates a new Color that is a brighter version of this Color.

      This method applies an arbitrary scale factor to each of the three RGB components of this Color to create a brighter version of this Color. The alpha value is preserved. Although brighter and darker are inverse operations, the results of a series of invocations of these two methods might be inconsistent because of rounding errors.

      Returns:
      a new Color object that is a brighter version of this Color with the same alpha value.
