There is no official way to do that for script-fu or
automatically-generated interface python-fu scripts (appart from
asking the user to type each coordinate, of course).


However, in my experience a good way to achieve coordinate input for
*-fu scripts is asking the user to draw a path (vector) on the image,
and using the first N control points of said path as the needed
coordinates. You can use the vectors pdb functions to read those
coordinates.
