'Declaration

Public Class AnnTextPointerObject 
   Inherits AnnTextObject
   Implements IAnnObjectCloneable

public sealed class AnnTextPointerObject : IAnnObjectCloneable

@interface LTAnnTextPointerObject : LTAnnTextObject<NSCoding,NSCopying>

public class AnnTextPointerObject extends AnnTextObject

function Leadtools.Annotations.Core.AnnTextPointerObject()

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:

The AnnTextPointerObject class inherits a number of properties from the AnnObject class, providing support for font, stroke and fill characteristics. These properties are listed below:

The AnnTextPointerObject inherits a number of text properties from the AnnTextObject class that provide support for text alignment, margins, etc. These properties are listed below:

The name of the text pointer object can be controlled using Labels property, inherited from the AnnObject class.

Each object can be transformed with the following methods:

The following properties can also be used to programmatically set characteristics of an AnnTextPointerObject:

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