colour.UCS_to_uv

colour.UCS_to_uv(UVW: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) → NDArrayFloat

Convert from CIE 1960 UCS colourspace to uv chromaticity coordinates.

Parameters:

UVW (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – CIE 1960 UCS \(UVW\) colourspace array.

Returns:

CIE UCS uv chromaticity coordinates.

Return type:

numpy.ndarray
