AnnPDFConvertor Class

Summary

Defines a class that converts between AnnObject annotation objects and PDFAnnotation annotation objects.

Syntax

WinRT C#

public static class AnnPDFConvertor

Public MustInherit NotInheritable Class AnnPDFConvertor

public sealed static class AnnPDFConvertor

function Leadtools.Annotations.Documents.AnnPDFConvertor()

Remarks

AnnPDFConvertor loads a PDF file with its annotations to allow conversion into AnnObject. Conversely, loads AnnObject to allow embedding core annotation objects into a PDF file by converting it to PDFAnnotation.

Example

This example demonstrates how to convert from AnnObject objects to PDFAnnotation objects and vice versa.

Imports Leadtools 
Imports Leadtools.Annotations.Core 
Imports Leadtools.Annotations.Documents 
Imports Leadtools.Pdf 
 
<TestMethod()> _ 
Public Sub AnnPDFConvertor_AnnPDFConvertor() 
   'Create some annotation objects and add it to container 
   Dim rectangle As AnnRectangleObject = New AnnRectangleObject() 
   Dim text As AnnTextObject = New AnnTextObject() 
   'Create new container and annotation object to it 
   Dim container As AnnContainer = New AnnContainer() 
   container.Children.Add(rectangle) 
   container.Children.Add(text) 
 
   'Create list of PDFAnnotation as target of our conversion 
   Dim pdfAnnotations As List(Of PDFAnnotation) = New List(Of PDFAnnotation)() 
 
   'Convert fro core annotation object to PDF annotation objects 
   AnnPDFConvertor.ConvertToPDF(container, pdfAnnotations, 800) 
 
   'Print the count of converted objects 
   Debug.WriteLine(pdfAnnotations.Count) ' the result will be "2" 
 
   'Now convert from PDF annotation objects to our core annotation objects  
   Dim newContainer As AnnContainer = New AnnContainer() 
 
   'Assume the size of pdf page that we want to add anotations to is 600*800 
   AnnPDFConvertor.ConvertFromPDF(pdfAnnotations, newContainer, LeadSizeD.Create(600, 800)) 
 
   'Print the count of converted objects 
   Debug.WriteLine(newContainer.Children.Count) ' the result will be "2" 
End Sub
