public class DocumentWriter 
@interface LTDocumentWriter : NSObject 
public class DocumentWriter 
public ref class DocumentWriter  

The DocumentWriter class is used to create multipage and searchable documents from one or more SVG, EMF or raster image based pages. Refer to LEADTOOLS Document Writers for more information.

Support for various popular formats is included, such as PDF, DOC/DOCX, HTML, RTF, XPS or Text. For a list of all the document formats supported, refer to the DocumentFormat enumeration.


This example shows how to create document file from SVG-based pages using basic functionality of the DocumentWriter class. For an example on creating documents from EMF objects, refer to DocumentWriterEmfPage and for an example on creating mixed documents from SVG, EMF and empty pages, refer to DocumentWriterRasterPage.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Document.Writer; 
using Leadtools.Ocr; 
public void DocumentWriterExample() 
   var inputFileName = Path.Combine(LEAD_VARS.ImagesDir, "test.docx"); 
   var outputFileName = Path.Combine(LEAD_VARS.ImagesDir, "Example.pdf"); 
   // Setup a new RasterCodecs object 
   var codecs = new RasterCodecs(); 
   codecs.Options.RasterizeDocument.Load.Resolution = 300; 
   // Get the number of pages in the input document 
   var pageCount = codecs.GetTotalPages(inputFileName); 
   // Create a new instance of the LEADTOOLS Document Writer 
   var docWriter = new DocumentWriter(); 
   // Change the PDF options 
   var pdfOptions = docWriter.GetOptions(DocumentFormat.Pdf) as PdfDocumentOptions; 
   pdfOptions.DocumentType = PdfDocumentType.PdfA; 
   docWriter.SetOptions(DocumentFormat.Pdf, pdfOptions); 
   // Create a new PDF document 
   Debug.WriteLine("Creating new PDF document: {0}", outputFileName); 
   docWriter.BeginDocument(outputFileName, DocumentFormat.Pdf); 
   // Loop through all the pages 
   for (var pageNumber = 1; pageNumber <= pageCount; pageNumber++) 
      // Get the page as SVG 
      Debug.WriteLine("Loading page {0}", pageNumber); 
      var page = new DocumentWriterSvgPage(); 
      page.SvgDocument = codecs.LoadSvg(inputFileName, pageNumber, null); 
      // Add the page 
      Debug.WriteLine("Adding page {0}", pageNumber); 
   // Finally finish writing the PDF file on disk
