Introduction
WPF AnnClosedCurveObject
Note: This topic is for Document/Medical only. The closed curve annotation object (AnnClosedCurveObject) is a sequence of points that are joined by cubic polynomials such that adjacent polynomials are continuous at the first and second derivatives. 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. With the automated functions, each curve is formed with a mouse click, and the object is completed on a double-click. You can change the points using the Points collection property. Programmatically, the points that define this curve object are contained in the Points property, inherited from the AnnPolylineObject class. Each object has a transformation associated with it. This transform is accessed through the RenderTransform property. The TransformMode property indicates how the transform will be used to transform The WPF annotation object. The AnnClosedCurveObject class inherits a number of properties from the AnnObject class that provide support for font, stroke and fill characteristics. These properties are listed below:
The name of the curve object can be controlled using the following properties, inherited from the AnnObject class:
- Header
- HeaderBackground
- HeaderDecorations
- HeaderFontFamilyName
- HeaderFontSize
- HeaderFontStretch
- HeaderFontStyle
- HeaderFontWeight
- HeaderForeground
- HeaderOffset
- IsHeaderRestricted
- IsHeaderVisible
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. The following properties can also be used to programmatically set characteristics of an AnnClosedCurveObject class object:
