Manages the automation mode for an annotation application.
The AnnAutomationManager class holds the collection of all AnnAutomation objects in the application, as well as various other user interface options.
An automated annotation application usually creates one AnnAutomationManager object per application.
The following example creates an automated annotation application. The following example will only use the line and rectangle objects. The example lets you draw objects on top of the image, select objects, move them or change them.
To run this example perform the following steps:
