spline ( ';' spline )*

  • where spline = (endp)? (startp)? point (triple)+
  • and triple = point point point
  • and endp = "e,%f,%f"
  • and startp = "s,%f,%f"

If a spline has points p₁ p₂ p₃ ... pₙ, (n = 1 (mod 3)), the points correspond to the control points of a cubic B-spline from p₁ to pₙ. If startp is given, it touches one node of the edge, and the arrowhead goes from p₁ to startp. If startp is not given, p₁ touches a node. Similarly for pₙ and endp.
