Saves an image stored as a Numpy array to a path or file object.

# Arguments
    path: Path or file object.
    x: Numpy array.
    data_format: Image data format,
        either "channels_first" or "channels_last".
    file_format: Optional file format override. If omitted, the
        format to use is determined from the filename extension.
        If a file object was used instead of a filename, this
        parameter should always be used.
    scale: Whether to rescale image values to be within `[0, 255]`.
    **kwargs: Additional keyword arguments passed to `PIL.Image.save()`.
