colour.io.LUT_to_LUT

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

Convert given LUT to given cls class instance.

Parameters

  • cls (Type[colour.io.luts.lut.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

  • cls (Type[colour.io.luts.lut.AbstractLUT]) –

  • force_conversion (bool) –

  • kwargs (Any) –

Return type

colour.io.luts.lut.AbstractLUT
