colour.utilities.ones#

colour.utilities.ones(shape: int | Sequence[int], dtype: Type[DTypeReal] | None = None) → NDArray[source]#

Create an array of ones with the active dtype.

Wrap np.ones() definition to create an array with the active numpy.dtype defined by the colour.constant.DTYPE_FLOAT_DEFAULT attribute.

Parameters:

shape (int | Sequence[int]) – Shape of the new array, e.g., (2, 3) or 2.
dtype (Type[DTypeReal] | None) – numpy.dtype to use for conversion, default to the numpy.dtype defined by the colour.constant.DTYPE_FLOAT_DEFAULT attribute.

Returns:

Array of the specified shape and numpy.dtype, filled with ones.

Return type:

numpy.ndarray

Examples

>>> ones(3)
array([1., 1., 1.])
