class EmfDocumentOptions(DocumentOptions):

Remarks

The Windows Enhanced Meta File (EMF) format does not support multipage documents. Therefore, only the last page added with the DocumentWriter.AddPage will be used in the final document.

Note that this format does not support calling DocumentWriter.InsertPage.

The options set in the EmfDocumentOptions class will be used when the user saves a document using the DocumentFormat.Emf format.

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

Use the DocumentWriter.GetOptions method of the DocumentWriter object being used. Pass DocumentFormat.Emf to the format parameter. Note that the resulting object from the base DocumentOptions class needs to be cast to EmfDocumentOptions.
Use the various EmfDocumentOptions 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 DocumentFormat.Emf for the format parameter) to create a new document and add the pages.

Note that this format does not support calling DocumentWriter.InsertPage.

Currently, the EmfDocumentOptions class contains no extra options.

Example

This example will create a new Windows Enhanced Meta File (EMF) file using the various supported options.

using Leadtools.Document.Writer; 
using Leadtools; 
using Leadtools.Codecs; 
 
 
 
public void EmfDocumentOptionsExample() 
{ 
   var inputFileName = Path.Combine(LEAD_VARS.ImagesDir, "test_ocr1.Ltd"); // LTD file that resulted from OCR 
   var outputFileName = Path.Combine(LEAD_VARS.ImagesDir, "Example.emf"); 
   // Create a new instance of the LEADTOOLS Document Writer 
   var docWriter = new DocumentWriter(); 
 
   // Change the EMF options 
   var emfOptions = docWriter.GetOptions(DocumentFormat.Emf) as EmfDocumentOptions; 
   // EMF currently does not have any extra options 
   // In the future, you can modify the options here if needed 
   docWriter.SetOptions(DocumentFormat.Emf, emfOptions); 
 
   // Create a new EMF document from LTD file 
   Console.WriteLine("Creating new EMF document : {0}", outputFileName); 
   docWriter.Convert(inputFileName, outputFileName, DocumentFormat.Emf); 
} 
 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
