SplineStart Element

Contains x- and y-coordinates for a spline's second control point, its second knot, its first knot, the last knot, and the degree of the spline. This information is contained in the X, Y, A, B, C, and D elements, respectively.

Syntax

  <SplineStart
    [IX]
    [Del]>
</SplineStart>

Attributes

IX

Optional int. The one-based index of the element within its parent element.

Del

Optional boolean. A flag indicating whether the element has been deleted locally. A value of 1 indicates that the element was deleted locally.

Remarks

In a DatadiagramML document, the definition of a spline in a Geom element contains a SplineStart element followed by one or more SplineKnot elements. The SplineStart element must be preceded by another kind of element, such as a MoveTo element, to indicate the first control point of the spline. The preceding element can be a LineTo, ArcTo, NURBSTo, PolylineTo or EllipticalArcTo element if the spline follows a segment of that type.

In any case, the first element in a Geom element (the element whose IX attribute is set to 1) must be a MoveTo, InfiniteLine, or Ellipse element.

The SplineStart element is relevant only when contained in a Shape element. It is ignored when contained in a DocumentSheet, PageSheet, or StyleSheet element.
