Remarks

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

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

  1. Use the DocumentWriter.GetOptions method of the DocumentWriter object being used. Passing DocumentFormat.Rtf to the format parameter. Note that the resulting object from the base DocumentOptions class needs to be cast to RtfDocumentOptions.
  2. Use the various RtfDocumentOptions properties to change the options.
  3. Use DocumentWriter.SetOptions to set the new options in the engine.
  4. Now you can call the DocumentWriter.BeginDocument method (with DocumentFormat.Rtf for the format parameter) to create a new document and add the pages.

The RtfDocumentOptions class contains the following properties:

Property Description
TextMode Controls how and when to frames the text blocks in the resulting RTF file.

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

Example

This example will create a new HyperText Markup Language document (RTF) file using the various supported options.
