colour.models.eotf_DCDM

colour.models.eotf_DCDM(XYZ_p, in_int=False)[source]

Defines the DCDM electro-optical transfer function (EOTF / EOCF).

Parameters:
  • XYZ_p (numeric or array_like) – Non-linear CIE XYZ’ tristimulus values.
  • in_int (bool, optional) – Whether to treat the input value as integer code value or float equivalent of a code value at a given bit depth.
Returns:

CIE XYZ tristimulus values.
Return type:

numeric or ndarray

Notes

Domain * Scale - Reference Scale - 1
XYZ_p [0, 1] [0, 1]
Range * Scale - Reference Scale - 1
XYZ [0, 1] [0, 1]
  • * This definition has an input integer switch, thus the domain-range scale information is only given for the floating point mode.
