------- Additional comments from [EMAIL PROTECTED] Sat Dec 2 15:46:50 -0800 2006 ------- You have subordered the B-spline variant under "smooth". I think, that is not correct. If you draw a B-spline, your data points are not points on the curve, but they are used as control points to form the B-spline curve. So a B-spline curve is more like a Bézier curve. It is complete different from smoothing a line with interpolation like in the case of cubic splines, which goes through the data points. People who know nothing about B-splines will be confused, what will become out of there polyline. Those who know, what a B-spline curve is, will be confused to find them as variant of a polyline. The resolution of the cubic spline divides the interval between neighbour points and you get different length, if the distance between the points are different. For B-splines the whole range from first to last point is divided in equal distances. Therefore B-Spline curves are so much different from cubic splines that they should get an icon beside the polyline variants and get a handling for them alone. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
