Perform a gray value closing on an image.
::gray_closing applies a gray value closing to the input image Image with the structuring element SE. The gray value closing of an image i with a structuring element s is defined as
i +- s = (i + s) - s ,i.e., a dilation of the image with s followed by an erosion with s (see ::gray_dilation and ::gray_erosion). For the generation of structuring elements, see ::read_gray_se.

image(-array) -> Hobject: HImage(Array) ( byte ) |

::gray_closing returns H_MSG_TRUE if the structuring element is not the empty region. Otherwise, an exception is raised.
