    Returns the result of an image function.

    :py:mod:`~PIL.ImageMath` only supports single-layer images. To process multi-band
    images, use the :py:meth:`~PIL.Image.Image.split` method or
    :py:func:`~PIL.Image.merge` function.

    :param expression: A function that receives a dictionary.
    :param **kw: Values to add to the function's dictionary.
    :return: The expression result. This is usually an image object, but can
             also be an integer, a floating point value, or a pixel tuple,
             depending on the expression.

    Evaluates an image expression. This uses Python's ``eval()`` function to process
    the expression string, and carries the security risks of doing so. It is not
    recommended to process expressions without considering this.
    :py:meth:`~lambda_eval` is a more secure alternative.

    :py:mod:`~PIL.ImageMath` only supports single-layer images. To process multi-band
    images, use the :py:meth:`~PIL.Image.Image.split` method or
    :py:func:`~PIL.Image.merge` function.

    :param expression: A string containing a Python-style expression.
    :param **kw: Values to add to the evaluation context.
    :return: The evaluated expression. This is usually an image object, but can
             also be an integer, a floating point value, or a pixel tuple,
             depending on the expression.
