Examples of RGBtoHSB()

java.awt.Color.RGBtoHSB()

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. @param r the red component of the color @param g the green component of the color @param b the blue component of the color @param hsbvals the array used to return the three HSB values, or null @return 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. @see java.awt.Color#getRGB() @see java.awt.Color#Color(int) @see java.awt.image.ColorModel#getRGBdefault() @since JDK1.0
