AnnAutomationManager Class

Summary

Manages the automation mode for an annotation application.

Syntax

C#
VB
C++
public class AnnAutomationManager 
  
Public Class AnnAutomationManager  
public ref class AnnAutomationManager

Remarks

The AnnAutomationManager class holds the collection of all AnnAutomation objects in the application as well the annotation toolbar. Cursor, keyboard, context sensitive menus, property dialogs and various other user interface options and settings are stored here as well.

An automated annotation application usually creates one AnnAutomationManager object per application.

Example

This example creates an automated annotation application. This example will only use the line and rectangle objects. The example lets you select objects from the toolbar, draw objects on top of the image, select objects and move them or change them, right click on any object to show its properties, etc.
