ConvertToPDF Method

Summary

Converts the annotation objects inside AnnContainer to a list of PDFAnnotation objects.

Syntax

C++/CLI

Java

Python

public static void ConvertToPDF( 
   AnnContainer source, 
   IList<PDFAnnotation> target, 
   double pdfPageHeight 
)

public static void convertToPDF(AnnContainer source, List<PDFAnnotation> target, double pdfPageHeight)

 function Leadtools.Pdf.Annotations.AnnPDFConvertor.ConvertToPDF(  
   source , 
   target , 
   pdfPageHeight  
)

public:  
   static void ConvertToPDF( 
      AnnContainer^ source, 
      IList<PDFAnnotation^>^ target, 
      double pdfPageHeight 
   )

def ConvertToPDF(self,source,target,pdfPageHeight):

Parameters

source
The source container that holds a list of annotation objects. This value must not be null.

target
The target list of PDFAnnotation to fill converted objects into. This value must not be null.

pdfPageHeight
The height of the PDF page to add annotations into.

Remarks

Note:The ConvertToPDF and ConvertFromPDF methods have different signatures for WinRT and WinRTPhone. Refer to the following for the correct signatures:

WinRT and WinRTPhone

public static void ConvertToPDF(AnnContainer source, IList<IPDFAnnotation> target, double pdfPageHeight) 
public static void ConvertFromPDF(IList<IPDFAnnotation> source, AnnContainer target, LeadSizeD pdfPageSize)

Example

Java

using Leadtools.Pdf.Annotations; 
using LeadtoolsExamples.Common; 
using Leadtools.Pdf; 
 
public void AnnPDFConvertor_AnnPDFConvertor() 
{ 
   //Create some annotation objects and add it to container 
   AnnRectangleObject rectangle = new AnnRectangleObject(); 
   AnnTextObject text = new AnnTextObject(); 
 
   //Create new container and annotation object to it 
   AnnContainer container = new AnnContainer(); 
   container.Children.Add(rectangle); 
   container.Children.Add(text); 
 
   //Create list of PDFAnnotation as target of our conversion 
   List<PDFAnnotation> pdfAnnotations = new List<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  
   AnnContainer newContainer = new AnnContainer(); 
 
   //Assume the size of pdf page that we want to add annotations 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"
