Image Annotation Tool Button Control

What the Image Annotation Tool Button control lets you do

The Image Annotation Tool Button (IATB) control lets you the application developer add image annotation functions to applications that support 32-bit ActiveX controls.

Specifically, you include one or more IATB controls in your application to create a custom annotation tool bar or palette.  Each control is actually a button that invokes an annotation type when the end user clicks on it.

Your custom annotation tool bar or palette can contain buttons that provide:

• Discrete annotation types
  
  
• The same annotation type with different annotation styles
  
  
• A combination of both

Note: The IATB control is an ActiveX control in:

• Imaging for Windows Professional Edition V1.0, V1.1, and V2.0
  
  
• Imaging for Windows 98

And an OCX control in:

• Imaging for Windows 95
  
  
• Imaging for Windows NT 4.0

What the IATB control lets your users do

Each IATB control lets your users draw text or graphical annotations on displayed image documents.

Prerequisites

You must include at least one Image Admin control and one Image Edit control in your application.

Further, you must link each IATB control to the Image Edit control that displays images to be annotated by your end users.

The link permits the IATB control to send messages to the Image Edit control.  These messages change the annotation properties of the Image Edit control to the values set within the IATB control.  It is the Image Edit control that actually draws the annotations.

To link an Image Annotation Tool Button control to an Image Edit control:

1. Set the DestImageControl property of the Image Annotation Tool Button control to the name of the desired Image Edit control.
   
   
2. Set the ImageControl property of the Image Edit control to the same Image Edit control name.
