Image Buffer Transfer Function Constants
Constants that indicate the transfer function for the image buffer.
Overview
Use the kCVImageBufferTransferFunctionKey key to attach one of these values to the image buffer. The transfer function describes the tonality of an image for use in color matching operations, along with a color primaries gamut (See Image Buffer Color Primaries Constants for more information.). Most apps should specify the kCVImageBufferTransferFunction_ITU_R_709_2 transfer function.
