        Example:

        ::

            da = nutszebra_data_augmentation_picture.DataAugmentationPicture()
            da.load_picture(path).rotate_picture_randomly()

        Args:
            x_or_probability Optional([int, float, str, numpy.ndarray]): If int or float, this argument is considered as the probability and self.x is used for convert_to_image_format. If str or numpy.ndarray, set this argument as self.x and execute crop_center with self.x.
            low (float): lower bound of random value (degree)
            high (float): higher bound of random value (degree)
            reshape (bool): If True, rorated picture is reshaped
            __no_record (bool): the value of __no_record changes the value to be returned.

        Returns:
            Optional([tuple, class]): If __no_record is False, return self, otherwise return tuple(shaped x, info)
