colour.utilities.as_int#

colour.utilities.as_int(a: ArrayLike, dtype: Type[DTypeInt] | None = None) → NDArrayInt[source]#

Attempt to convert given variable \(a\) to numpy.integer using given numpy.dtype. If variable \(a\) is not a scalar or 0-dimensional, it is converted to numpy.ndarray.

Parameters:

  • a (ArrayLike) – Variable \(a\) to convert.

  • dtype (Type[DTypeInt] | None) – numpy.dtype to use for conversion, default to the numpy.dtype defined by the colour.constant.DTYPE_INT_DEFAULT attribute.

Returns:

Variable \(a\) converted to numpy.integer.

Return type:

numpy.ndarray

Examples

>>> as_int(np.array(1))
1
>>> as_int(np.array([1]))  
array([1])
>>> as_int(np.arange(10))  
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]...)
