eotf_reverse_DCDM
(XYZ, out_int=False)[source]¶ Defines the DCDM reverse electro-optical transfer function (EOTF / EOCF).
Parameters: - XYZ (numeric or array_like) – CIE XYZ tristimulus values.
- out_int (bool, optional) – Whether to return value as integer code value or float equivalent of a code value at a given bit depth.
Returns: Non-linear CIE XYZ’ tristimulus values.
Return type: numeric or ndarray
Notes
Domain * Scale - Reference Scale - 1 XYZ
[0, 1] [0, 1] Range * Scale - Reference Scale - 1 XYZ_p
[0, 1] [0, 1] - * This definition has an output integer switch, thus the domain-range scale information is only given for the floating point mode.
