class DocumentOptions:

Remarks

You cannot use the DocumentOptions class directly. Instead, use one of the derived classes to get and set the options associated with that document format. The following table lists the document formats and the corresponding DocumentOptions derived class associated with each format:

Format	Class
DocumentFormat.Ltd	LtdDocumentOptions
DocumentFormat.Pdf	PdfDocumentOptions
DocumentFormat.Doc	DocDocumentOptions
DocumentFormat.Rtf	RtfDocumentOptions
DocumentFormat.Html	HtmlDocumentOptions
DocumentFormat.Text	TextDocumentOptions
DocumentFormat.Emf	EmfDocumentOptions
DocumentFormat.Xps	XpsDocumentOptions
DocumentFormat.Docx	DocxDocumentOptions
DocumentFormat.Xls	XpsDocumentOptions
DocumentFormat.AltoXml	AltoXmlDocumentOptions

To change the options used with a particular format, perform the following steps:

Call the DocumentWriter.GetOptions method for the DocumentWriter object being used, passing the DocumentFormat to be used in the format parameter. The resulting object from the base DocumentOptions class needs to be cast to the appropriate derived class described in the previous table.
Use the various derived class properties to change the options.
Call DocumentWriter.SetOptions to set the new options for the engine.
Now call the DocumentWriter.BeginDocument method (using the DocumentFormat value for the format parameter) to create a new document and add the pages.

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(); 
}
