colour.models.eotf_inverse_DCDM#
- colour.models.eotf_inverse_DCDM(XYZ: ArrayLike, out_int: bool = False) NDArrayReal [source]#
Define the DCDM inverse electro-optical transfer function (EOTF).
- Parameters:
XYZ (ArrayLike) – CIE XYZ tristimulus values.
out_int (bool) – Whether to return value as int code value or float equivalent of a code value at a given bit-depth.
- Returns:
Non-linear CIE XYZ’ tristimulus values.
- Return type:
Warning
DCDM is an absolute transfer function.
Notes
DCDM is an absolute transfer function, thus the domain and range values for the Reference and 1 scales are only indicative that the data is not affected by scale transformations.
