The curve annotation object (
AnnCurveObject) is a sequence of points that are joined by cubic polynomials such that adjacent polynomials are continuous at the first and second derivatives. The result is a smooth, continuous curve going through all the points. With the automated functions, each curve is formed with a mouse click, and the object is completed on a double-click.
Programmatically, the points that define this curve object are contained in the
Points property, inherited from the
AnnPolylineObject class. Each object has a transformation matrix associated with it. This matrix is accessed through the
Transform property. The
TransformObjectMode property indicates how the transform matrix will be used to transform the annotation object. The
PhysicalTransform property is used to convert the logical coordinates of the points to physical coordinates. The matrix in this property is the result of multiplying the matrix in the Transform property with the matrix in the container's
Transform property.
The
AnnCurveObject class inherits a number of properties from the
AnnDrawable class that provide support for font, pen and brush characteristics. These properties are listed below:
The name of the curve object can be controlled using the following properties, inherited from the
AnnObject class:
The boundaries and location of the curve object can be controlled using the following properties, also inherited from the
AnnObject class:
An object can be part of a group annotation object or part of a container object. It cannot be part of both a group and a container at the same time. The
Container property and the
Group property, both inherited from the
AnnObject class, contain information on the container or the group to which the object belongs.
The following properties can also be used to programmatically set characteristics of an
AnnCurveObject class object:
