Constructor Detail

RGBColor

public RGBColor(double r,
                double g,
                double b)

Instantiates an RGB color from r, g and b components represented as doubles in the range 0..1

Parameters:

r - red component

g - green component

b - blue component

RGBColor

public RGBColor(int r,
                int g,
                int b)

Instantiates an RGB color from r, g and b components represented as ints in the range 0..255

Parameters:

r - red component

g - green component

b - blue component

RGBColor

public RGBColor(double[] rgb)

Instantiates an RGB color.

Parameters:

rgb - an array with three entries for r, g, and b components represented as doubles in the range 0..1

RGBColor

public RGBColor()

Instantiates an RGB color with all components set to 0 (i.e., black)

Method Detail

r

public double r()

Returns:

the red component

setR

public void setR(double r)

Parameters:

r - the red component (0..1) to set

g

cmyk - an array of four doubles in the range 0..1, representing c, m, y and k components

Returns:

the "equivalent" RGB color

cmyk2rgb

public static RGBColor cmyk2rgb(CMYKColor cmyk)

Uses the standard quick and dirty direct transform of CMYK to RGB. You can use it, but don't believe it.

Parameters:

cmyk - a CMYKColor

Returns:

the "equivalent" RGB color
