colour.io.write_LUT_SonySPI1D#

colour.io.write_LUT_SonySPI1D(LUT: Union[LUT1D, LUT3x1D, LUTSequence], path: str, decimals: int = 7) bool[source]#

Write given LUT to given Sony .spi1d LUT file.

Parameters:
  • LUT (Union[LUT1D, LUT3x1D, LUTSequence]) – LUT1D, LUT3x1D 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 1D Sony .spi1d LUT:

>>> from colour.algebra import spow
>>> domain = np.array([-0.1, 1.5])
>>> LUT = LUT1D(
...     spow(LUT1D.linear_table(16), 1 / 2.2),
...     'My LUT',
...     domain,
...     comments=['A first comment.', 'A second comment.'])
>>> write_LUT_SonySPI1D(LUT, 'My_LUT.cube')  

Writing a 3x1D Sony .spi1d LUT:

>>> domain = np.array([[-0.1, -0.1, -0.1], [1.5, 1.5, 1.5]])
>>> LUT = LUT3x1D(
...     spow(LUT3x1D.linear_table(16), 1 / 2.2),
...     'My LUT',
...     domain,
...     comments=['A first comment.', 'A second comment.'])
>>> write_LUT_SonySPI1D(LUT, 'My_LUT.cube')
