AnnAutomationManager Object

Summary

Manages the automation mode for an annotation application.

Syntax

JavaScript Syntax
function lt.Annotations.Automation.AnnAutomationManager
TypeScript Syntax
class lt.Annotations.Automation.AnnAutomationManager()

Remarks

The AnnAutomationManager class holds the collection of all AnnAutomation objects in the application as well various other user interface options.

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

Example

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 and move them or change them.

To run this example perform the following steps:

    Copy and paste this example into your favorite text editor and save it as an HTML file with any name (for example, "Default.htm"), to a folder on your disk.Inside the folder containing the new HTML file, create a directory with the name "Scripts".Copy the required .js files in the example from the <LEADTOOLS_INSTALLDIR>\Bin\JS" to "Scripts. Finally, open the HTML file in any browser that supports HTML 5.
