Closed Curve Tool

(Document and Medical Imaging toolkits)

The closed curve annotation object (ANNOBJECT_CURVECLOSED) is a sequence of points that are joined by cubic polynomials such that adjacent polynomials are continuous at the first and second derivates. Unlike the curve annotation object, the first and last endpoints are also joined by a curve. The result is a smooth, continuous closed curve going through all the points.

In design mode, click on the object with the right mouse button to do the following:
