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()

Creates DeviceRgb color with all colorants intensities initialised as zeroes.
