Re: [Gimp-user] create a custom tool or run script at cursor?

That would actually work almost quite as well if one can get the script only
to do things at the nodes. Possible?

Sure - here is a script that labels each point of a node:

The key chunk you are interested in is here:
        ; get all the points in the path as a ((x1 x1) (x2 y2) ...) list
        (while (< counter numstrokes)  ; for each stroke in the path
          (set! points (caddr (gimp-vectors-stroke-get-points inPath (vector-ref strokelist counter))))


          (set! numpoints (/ (cadr (gimp-vectors-stroke-get-points inPath (vector-ref strokelist counter))) 6))
 
          (let
            ((pcount 0))
		    (while (< pcount numpoints)
              (set! pointlist (append pointlist (list (list (vector-ref points (+ (* pcount 6) 2)) (vector-ref points (+ (* pcount 6) 3))))))


              (set! pcount (+ pcount 1))
            )
          )
          (set! counter (+ counter 1))
        ) 
Of course, it needs a few defines up front....
