Why would it exist? You never create it.
The following is more correct nstrokes, strokes = pdb.gimp_vectors_get_strokes(vectors) len0 = pdb.gimp_vectors_stroke_get_length(vectors, strokes[0], 100.0) > the vectors and strokes went fine but I could not get the length > > I then thought maybe I should try using tinyscheme and tried the following > (let* ( > (count 0) > (vector (car(gimp-image-get-active-vectors img))) > (strokes (cadr(gimp-vectors-get-strokes vector))) > (len (caddr(gimp-vectors-stroke-get-length vector (aref strokes > count) 100.0))) > ) > (print (list len vector)) > I still get an unbound variable error. a search fo previous implementations > did not show much.
