• true, the point is added to the existing guide; • default, the point is added to a new guide; • false, the point is omitted and a new guide is begun. The points are connected using the interpolation specified by join: • operator -- (linear interpolation; the abbreviation Straight is also accepted); • operator .. (piecewise Bezier cubic spline interpolation; the abbreviation Spline is also accepted); • Hermite (standard cubic spline interpolation using boundary condition notaknot, natural, periodic, clamped(real slopea, real slopeb)), or monotonic. The abbreviation Hermite is equivalent to Hermite(notaknot) for nonperiodic data and Hermite(periodic) for periodic data). •
