colour.models.IPT_hue_angle

colour.models.IPT_hue_angle(IPT: Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) → Annotated[ndarray[tuple[Any, ...], dtype[float16 | float32 | float64]], 360]

Compute the hue angle in degrees from the IPT colourspace array.

Parameters:

IPT (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 1]) – IPT colourspace array.

Returns:

Hue angle in degrees.

Return type:

numpy.ndarray
