Detailed Description
A calibrated RGB color space.
A CalRGB color space (Red, Green, Blue) is a CIE-based ABC color space with only one transformation stage instead of two.
In this type of space, A, B, and C represent calibrated red, green, and blue color values. These three color components must be in the range 0.0 to 1.0; component values falling outside that range are adjusted to the nearest valid value without error indication.

Constructor & Destructor Documentation
CalRGBColorSpace
CalRGBColorSpace(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 CalRGB color space.
The blackPoint defaults to [0.0, 0.0, 0.0].
The gamma defaults to [1.0, 1.0, 1.0].
The matrix defaults to [1 0 0 0 1 0 0 0 1]

CalRGBColorSpace(System.Collections.Generic.IList< System.Double > whitePoint, System.Collections.Generic.IList< System.Double > blackPoint, System.Collections.Generic.IList< System.Double > gamma, System.Collections.Generic.IList< System.Double > matrix)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: System.Collections.Generic.IList< System.Double >An array of three numbers [ GR GG GB ] specifying the gamma for the red, green, and blue (A, B, and C) components of the color space.
matrix: System.Collections.Generic.IList< System.Double >An array of nine numbers [ XA YA ZA XB YB ZB XC YC ZC ] specifying the linear interpretation of the decoded A, B, and C components of the color space with respect to the final XYZ representation.
Create a CalRGB color space.

Name
string Name[get]The name of the color space. A named color space may be named something like DeviceRGB. More complicated color spaces may have a name like Indexed or ICCBased.
NumComponents
int NumComponents[get]The number of components in the color space.
For example, DeviceGray has 1 component, DeviceRGB has 3, and DeviceCMYK has 4.
