AnnTextUnderlineObject Class


Defines an annotation underline text review object.


WinRT C#
public class AnnTextUnderlineObject : AnnTextReviewObject 
public sealed class AnnTextUnderlineObject : Leadtools.Annotations.Core.IAnnObjectCloneable   
@interface LTAnnTextUnderlineObject: LTAnnTextReviewObject<NSCoding,NSCopying> 
public class AnnTextUnderlineObject extends AnnTextReviewObject 
function Leadtools.Annotations.Core.AnnTextUnderlineObject() 
   ref class AnnTextUnderlineObject : AnnTextReviewObject 


AnnTextUnderlineObject derives from AnnTextReviewObject and has a renderer that will draw a thick horizontal line near the bottom of each rectangle using the current Fill value. The thickness and location of the line is a ratio of the height of each rectangle and can be controlled by the renderer. The constructor of this object will create a solid green brush and set it in Fill.

Text underline is used by application such as Microsoft Word and Adobe Acrobat to emphasize part of the text in review mode. The LEADTOOLS Document Viewer uses text underline for this purpose. It also stores any text notes added by the reviewer in the metadata of the AnnObject using the AnnObject.ContentMetadataKey key.

Programmatically, the boundaries and rectangles of the text underline object can be controlled using the following properties:


using LeadtoolsExamples.Common; 
using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Core; 
using Leadtools.Codecs; 
using Leadtools.Annotations.WinForms; 
public void AnnCore_AnnTextUnderlineObject() 
   // assumes _automation is valid 
   double inch = 720.0; 
   // Add a TextUnderLine object 
   AnnTextUnderlineObject textUnderLineObj = new AnnTextUnderlineObject(); 
   // Set the rectangle for the Text UnderLine 
   textUnderLineObj.AddRectangle(LeadRectD.Create(inch * 1, inch * 1, inch * 2, inch * 2)); 
   // Set the MetaData 
   textUnderLineObj.Metadata[AnnObject.ContentMetadataKey] = "This is content"; 
   textUnderLineObj.Metadata[AnnObject.AuthorMetadataKey] = Environment.UserName; 
   textUnderLineObj.Metadata[AnnObject.CreatedMetadataKey] = DateTime.Now.ToString(); 
   // Add the object to the automation container
