def SetOptions(self,format,options):

Parameters

format
The document format.

options
An instance of an object derived from DocumentOptions. The remarks section lists the various document formats and the derived object that can be used.

Remarks

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

Format (the value of 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:

Use the DocumentWriter.GetOptions method of the DocumentWriter object you are using passing DocumentFormat desired in to the format parameter. Note that the resulting object from the base DocumentOptions class needs to be cast to appropriate derived class described in the table above.
Use the various derived class properties to change the options.
Use DocumentWriter.SetOptions to set the new options in the engine.
Now you can call the DocumentWriter.BeginDocument method (with the desired DocumentFormat 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(); 
}
