Curve Tool

(Document and Medical Imaging toolkits)

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

In design mode, each curve is formed with a mouse click, and the object is completed on a double click.

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

For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
