Constructor Detail

DeviceRgb

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

Creates DeviceRgb color by intensities of red, green and blue colorants. The intensities are considered to be in [0, 255] gap, if not, the intensity will be considered as 255 (when colorant's value is bigger than 255) or 0 (when colorant's value is less than 0).

Parameters:

r - the intensity of red colorant

g - the intensity of green colorant

b - the intensity of blue colorant

DeviceRgb

public DeviceRgb(float r,
                 float g,
                 float b)

Creates DeviceRgb color by intensities of red, green and blue colorants. The intensities are considered to be in [0, 1] interval, if not, the intensity will be considered as 1 (when colorant's value is bigger than 1) or 0 (when colorant's value is less than 0).

Parameters:

r - the intensity of red colorant

g - the intensity of green colorant

b - the intensity of blue colorant

DeviceRgb

public DeviceRgb(Color color)

Create DeviceRGB color from R, G, B values of java.awt.Color

Note, that alpha chanel is ignored, but opacity still can be achieved in some places by using 'setOpacity' method or 'TransparentColor' class.

Parameters:

color - the color which RGB values are used

DeviceRgb

public DeviceRgb()

Creates DeviceRgb color with all colorants intensities initialised as zeroes.

Parameters:

rgbColor - the DeviceRgb color to be made lighter

Returns:

lighter color

makeDarker

public static DeviceRgb makeDarker(DeviceRgb rgbColor)

Returns DeviceRgb color which is darker than given one

Parameters:

rgbColor - the DeviceRgb color to be made darker

Returns:

darker color
