colour.models.oetf_inverse_DaVinciIntermediate(V: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1], constants: Structure | None = None) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 1]

Apply the DaVinci Intermediate inverse opto-electronic transfer function (OETF).

Parameters:

• V (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – Encoded value \(V\).

• constants (Structure | None) – DaVinci Intermediate colour component transfer function constants.

Returns:

Linear light value \(L\).

Return type:

numpy.ndarray
