colour.io.write_LUT_IridasCube#

colour.io.write_LUT_IridasCube(LUT: Union[LUT3x1D, LUT3D, LUTSequence], path: str, decimals: int = 7) bool[source]#

Write given LUT to given Iridas .cube LUT file.

Parameters:
  • LUT (Union[LUT3x1D, LUT3D, LUTSequence]) – LUT3x1D, LUT3D or LUTSequence class instance to write at given path.

  • path (str) – LUT path.

  • decimals (int) – Formatting decimals.

Returns:

Definition success.

Return type:

bool

Warning

  • If a LUTSequence class instance is passed as LUT, the first LUT in the LUT sequence will be used.

Examples

Writing a 3x1D Iridas .cube LUT:

>>> from colour.algebra import spow
>>> domain = np.array([[-0.1, -0.2, -0.4], [1.5, 3.0, 6.0]])
>>> LUT = LUT3x1D(
...     spow(LUT3x1D.linear_table(16, domain), 1 / 2.2),
...     "My LUT",
...     domain,
...     comments=["A first comment.", "A second comment."],
... )
>>> write_LUT_IridasCube(LUTxD, "My_LUT.cube")
