Property Value

Document resolution value given in dots per inch unit and it controls the dimensions of the empty page. Default value is 0 (use the current screen resolution).

Remarks

The DocumentWriter class supports creating document with empty pages. To create an empty page, use a DocumentWriterPage structure with its EmfHandle set to IntPtr.Zero and pass it to the DocumentWriter.AddPage or DocumentWriter.InsertPage methods. You can control the size of this empty page in inches by setting the EmptyPageWidth, EmptyPageHeight and EmptyPageResolution properties to the desired values.

Note that in order to create empty pages, the PageRestriction property must be set to DocumentPageRestriction.Relaxed.

Example

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); 
      docWriter.AddPage(page); 
 
      page.SvgDocument.Dispose(); 
   } 
 
   // Finally finish writing the PDF file on disk 
   docWriter.EndDocument(); 
   codecs.Dispose(); 
}
