Detailed Description
A calibrated gray color space.
A CalGray color space is a special case of a single-component CIE-based color space, known as a CIE-based A color space.
This type of space is the one-dimensional (and usually achromatic) analog of CIE-based ABC spaces.

CalGrayColorSpace
CalGrayColorSpace(CalGrayColorSpacerhs, InternalConstructsignifier)Parameters
rhs: CalGrayColorSpacesignifier: InternalConstruct
CalGrayColorSpace
CalGrayColorSpace(System.Collections.Generic.IList< System.Double >whitePoint)Parameters
whitePoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.
Create a CalGray color space.
The blackPoint defaults to [0.0, 0.0, 0.0].
The gamma defaults to 1
CalGrayColorSpace
CalGrayColorSpace(System.Collections.Generic.IList< System.Double >whitePoint, System.Collections.Generic.IList< System.Double >blackPoint, doublegamma)Parameters
whitePoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.
blackPoint: System.Collections.Generic.IList< System.Double >An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point. All three of these numbers must be non-negative.
gamma: doubleA number G defining the gamma for the gray component. G must be positive and is generally greater than or equal to 1.
Create a CalGray color space.
