AnnTextRollupObject Class

Summary

This class provides support for creating and managing text rollup annotation objects.

Syntax

C++

[SerializableAttribute()] 
public class AnnTextRollupObject : Leadtools.Annotations.AnnNoteObject, Leadtools.Annotations.IAnnTextObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

  
<SerializableAttribute()> 
Public Class AnnTextRollupObject  
   Inherits Leadtools.Annotations.AnnNoteObject 
   Implements Leadtools.Annotations.IAnnTextObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

[SerializableAttribute()] 
public ref class AnnTextRollupObject : public Leadtools.Annotations.AnnNoteObject, Leadtools.Annotations.IAnnTextObject, System.ICloneable, System.IDisposable, System.Runtime.Serialization.ISerializable

Remarks

The text rollup annotation object extends AnnNoteObject by adding an Expanded property. When this property is set to false, the text rollup object looks and behaves like a normal note. When Expanded is set to false, the text rollup object will shrink to show only one line of text. This saves space on the container surface. For more information, refer to Using Text in Annotation Object. (Deprecated) For more information about the text rollup annotation object refer to AnnTextRollupObject (Deprecated). For more information about the automated text rollup annotation object, refer to Annotation Objects - Automated Features (Deprecated).

Example

This example creates a new text rollup object.

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
private void AnnTextRollupObject_AnnTextRollupObject(RasterImageViewer viewer, AnnContainer container) 
{ 
   AnnTextRollupObject textRollup = new AnnTextRollupObject(); 
   textRollup.Text = "My TextRollup object"; 
   textRollup.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular); 
   textRollup.EdgeMargin = AnnLength.Empty; 
   textRollup.ShadowBorderWidth = new AnnLength(6, AnnUnit.Pixel); 
   textRollup.Alignment = StringAlignment.Center; 
   textRollup.LineAlignment = StringAlignment.Center; 
   textRollup.Bounds = new AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel); 
   container.Objects.Add(textRollup); 
 
   textRollup.Expanded = false; 
   viewer.Invalidate(textRollup.InvalidRectangle); 
   MessageBox.Show("Not expanded"); 
 
   textRollup.Expanded = true; 
   viewer.Invalidate(textRollup.InvalidRectangle); 
   MessageBox.Show("expanded"); 
}
