colour.eotf_inverse#

colour.eotf_inverse(value: ArrayLike, function: LiteralEOTFInverse | str = 'ITU-R BT.1886', **kwargs: Any) → NDArrayFloat | NDArrayInt[source]#

Apply the specified inverse electro-optical transfer function (EOTF).

Parameters:

value (ArrayLike) – Display-linear value.
function (LiteralEOTFInverse | str) – Inverse electro-optical transfer function (EOTF).
kwargs (Any) – {colour.models.eotf_inverse_DCDM(), colour.models.eotf_inverse_DICOMGSDF(), colour.models.eotf_inverse_BT1886(), colour.models.eotf_inverse_BT2100_HLG(), colour.models.eotf_inverse_BT2100_PQ(), colour.models.eotf_inverse_ST2084(), colour.models.eotf_inverse_sRGB()}, See the documentation of the previously listed definitions.

Returns:

Non-linear signal value.

Return type:

numpy.ndarray
