Expand description

Determine the function needed to apply the given AVColorTransferCharacteristic to linear input.

The function returned should expect a nominal domain and range of [0.0-1.0] values outside of this range maybe valid depending on the chosen characteristic function.

@return Will return pointer to the function matching the supplied Transfer Characteristic. If unspecified will return NULL:
