Show in webframe
Example 
Members 
Manages the automation mode for an annotation application.
Object Model
Syntax
function Leadtools.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

This example creates an automated annotation application. This 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 take the following steps:

  1. Copy and paste this example into your favorite text editor and save it as an html file with any name, such as Default.htm, to a folder on your disk.
  2. Inside that folder containing the new html file, create a directory with the name "Scripts".
  3. Copy the required .js files in the example from "LEADTOOLS Installation Folder\Bin\JS" to "Scripts".
  4. Finally, open the HTML file in any browser that supports HTML 5.
