Namespace:Datalogics::PDFL

Inherits from:: ColorSpace

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.

Constructor & Destructor Documentation

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(System.Collections.Generic.IList< System.Double > whitePoint, System.Collections.Generic.IList< System.Double > blackPoint, double gamma)

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: double: A 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.
