Remarks

The text pointer annotation object extends the AnnTextObject class by providing an extra line that starts from one of the four corners of the bounding rectangle, around the text. The other endpoint of the line can be moved to point to anything on the underlying image. This extra endpoint may or may not be fixed, depending on the FixedPointer value.

Programmatically, the boundaries and location of the text pointer object can be controlled using the following properties:

Example

This example creates a text pointer object and adds it to the automation container.

C#
using LeadtoolsExamples.Common; 
using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
 
public void AnnCore_AnnTextPointerObject() 
{ 
 
   // assumes _automation is valid 
   double inch = 720.0; 
 
   // Add a text pointer object 
   AnnTextPointerObject textPointerObj = new AnnTextPointerObject(); 
 
   // Set the points for the hotspot 
   textPointerObj.Points.Add(LeadPointD.Create(1 * inch, 1 * inch)); 
   textPointerObj.Points.Add(LeadPointD.Create(2 * inch, 1 * inch)); 
   textPointerObj.Points.Add(LeadPointD.Create(2 * inch, 2 * inch)); 
   textPointerObj.Points.Add(LeadPointD.Create(1 * inch, 2 * inch)); 
 
   // Set the text 
   textPointerObj.Text = "sample text for object\nsecond line of text\nlast line"; 
 
   // Set the pointer 
   textPointerObj.FixedPointer = false; 
   textPointerObj.PointerPosition = LeadPointD.Create(4 * inch, 5 * inch); 
 
   // Add the object to the automation container 
   _automation.Container.Children.Add(textPointerObj); 
}
