WPF AnnRulerObject
Note: This topic is for Document/Medical only. The ruler annotation object (AnnRulerObject) is a simple line with gauges on both ends for measuring distance. With the automated functions, the ruler is started on a mouse-down event and completed on a mouse-up event. Programmatically, the boundaries and location of the ruler object can be controlled using the following properties:

- IsRulerImplemented
- ShowGauge
- ShowLength
- ShowTickMarks
- TickMarksLength

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 following properties can also be used to programmatically set characteristics of an AnnRulerObject class object:
- Hyperlink
- IsLocked
