An array of 3 numbers specifying the tristimulus value, in the CIE 1931 XYZ-space, of the diffuse white point.
An array of 3 numbers specifying the tristimulus value, in CIE 1931 XYZ-space, of the diffuse black point.
An array of 3 numbers specifying the gamma for the red, green, and blue components of the color space.
An array of 9 numbers specifying the linear interpretation of the gamma-modified RGB values of the color space with respect to the final XYZ representation.
A new calibrated RGB color space. You are responsible for releasing this object by calling
CGColor. If unsuccessful, returns
Creates a device-independent RGB color space that represents colors relative to a reference white point. This white point is based on the whitest light that can be generated by the output device. Colors in a device-independent color space should appear the same when displayed on different devices, to the extent that the capabilities of the device allow.
For color spaces that require a detailed gamma, such as the piecewise transfer function used in sRGB or ITU-R BT.709, you may want to use the function
CGColor instead, because it can accurately represent these gamma curves.
