colour.models.eotf_inverse_DCDM¶
- colour.models.eotf_inverse_DCDM(XYZ: FloatingOrArrayLike, out_int: Boolean = False) Union[FloatingOrNDArray, IntegerOrNDArray] [source]¶
Define the DCDM inverse electro-optical transfer function (EOTF).
- Parameters
XYZ (FloatingOrArrayLike) – CIE XYZ tristimulus values.
out_int (Boolean) – 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
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.
