colour.io.LUT_to_LUT#

colour.io.LUT_to_LUT(LUT: AbstractLUT, cls: Type[AbstractLUT], force_conversion: bool = False, **kwargs: Any) → AbstractLUT[source]#

Convert given LUT to given cls class instance.

Parameters:

LUT (AbstractLUT) – LUT to convert.
cls (Type[AbstractLUT]) – LUT class instance.
force_conversion (bool) – Whether to force the conversion if destructive.
channel_weights – Channel weights in case of a downcast from a LUT3x1D or LUT3D class instance.
interpolator – Interpolator class type to use as interpolating function.
interpolator_kwargs – Arguments to use when instantiating the interpolating function.
size – Expected table size in case of an upcast to or a downcast from a LUT3D class instance.
kwargs (Any)

Returns:

Converted LUT class instance.

Return type:

colour.LUT1D or colour.LUT3x1D or colour.LUT3D

Warning

Some conversions are destructive and raise a ValueError exception by default.

Raises:

ValueError – If the conversion is destructive.

Parameters:

LUT (AbstractLUT)
cls (Type[AbstractLUT])
force_conversion (bool)
kwargs (Any)

Return type:

AbstractLUT
