+Image.alpha_composite: dest
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-TODO
+When calling :py:meth:`~PIL.Image.Image.alpha_composite`, the ``dest`` argument now
+accepts negative co-ordinates, like the upper left corner of the ``box`` argument of
+:py:meth:`~PIL.Image.Image.paste` can be negative. Naturally, this has effect of
+cropping the overlaid image.
