Creates DeviceRgb color with all colorants intensities initialised as zeroes.

public DeviceRgb()

DeviceRgb(Color)

Create DeviceRGB color from R, G, B values of System.Drawing.Color
Note, that alpha chanel is ignored, but opacity still can be achieved in some places by using 'setOpacity' method or 'TransparentColor' class.

public DeviceRgb(Color color)

Parameters

color Color

the color which RGB values are used

DeviceRgb(int, int, int)

Creates DeviceRgb color by intensities of red, green and blue colorants.

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

Parameters

r int

the intensity of red colorant

g int

the intensity of green colorant

b int

the intensity of blue colorant

Remarks

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).

DeviceRgb(float, float, float)

Creates DeviceRgb color by intensities of red, green and blue colorants.

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

Parameters

r float

the intensity of red colorant

g float

the intensity of green colorant

b float

the intensity of blue colorant

Remarks

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).
