SplineKnot Row (Geometry Section)
Contains x - and y -coordinates for a spline's control point and a spline's knot.
A SplineKnot row contains the following cells.
||The x -coordinate of a control point.
||The y -coordinate of a control point.
||One of the spline's knots (other than the last one or the first two).
Visio displays the definition of a spline in a Geometry section that contains a SplineStart row followed by one or more SplineKnot rows. The SplineStart row must be preceded by another kind of row, such as a MoveTo row, to indicate the first control point of the spline. The preceding row can be a LineTo, ArcTo, NURBSTo, PolylineTo, or EllipticalArcTo row if the spline follows a segment of that type.
