reuse image.display() window?

Is there a way to use GraphicsMagick to display an Image, but somehow 
retain control of the display window so that subsequent images can be 
displayed in the same window?

For example, if I have images being acquired at, say, 1 hz is there some 
way that I can overwrite/replace the older image in the same window when 
a new one arrives using GraphicsMagick?

The display() function for an image object works fine for a single 
image, but the user must close the window.

I found references to functions like MagickXPasteImage in display.h but 
couldn't determine if that might be useful to me, or how that might be used.

Thanks!
