colour.utilities.MixinDataclassArray

class colour.utilities.MixinDataclassArray

Bases: colour.utilities.array.MixinDataclassIterable

A mixin providing conversion methods for dataclass-like class conversion to numpy.ndarray class.

Methods

• __array__()

Notes

• The colour.utilities.MixinDataclassArray class inherits the methods from the following classes:

  • colour.utilities.MixinDataclassIterable

  • colour.utilities.MixinDataclassFields

__array__(dtype: Optional[Type[DTypeNumber]] = None) → NDArray

Implement support for dataclass-like class conversion to numpy.ndarray class.

A field set to None will be filled with np.nan according to the shape of the first field not set with None.

Parameters

dtype (Optional[Type[DTypeNumber]]) – numpy.dtype to use for conversion to np.ndarray, default to the numpy.dtype defined by colour.constant.DEFAULT_FLOAT_DTYPE attribute.

Returns

dataclass-like class converted to numpy.ndarray.

Return type

numpy.ndarray
