Curve Tool

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:

Undo the last user action.
Cut or copy the object to the clipboard.
Delete the object.
Select all objects.
Bring the object to the front or send it to the back.
Lock and unlock annotation objects. See Password Dialog Box for Annotations.
(If the object has multiple nodes) Add or delete nodes. Add a node by clicking on the spot where you wish to add a node, then select Add Node. To delete a node, click on the node you wish to delete and select Delete Node.
Change the Name properties. See Name Dialog Box for Annotations.
Change the line width and style properties. See Line Dialog Box for Annotations.
Change the binary raster operation (ROP2) code. See ROP2 Dialog Box for Annotations.
Change the foreground color. See Color Dialog Box for Annotations.
Change the node properties. See Nodes Dialog Box for Annotations.
Change the fixed properties. See Fixed Dialog Box for Annotations.
Set and manage hyperlink properties for an object or group of objects. Note: The actual management of a hyperlink must be done through low-level implementation. Only the Menu Item "Hyperlink" and an associated event are provided through the automation object. For more information, refer to Implementing Annotation Hyperlinks.

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

For low-level implementation details, refer to Curve Annotation Object.
