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
RtfDocumentOptions.Framed	Turn off or on the option to put the text blocks inside a frame (text box object) in the resulting RTF file.

System.Object
   Leadtools.Forms.DocumentWriters.DocumentOptions
      Leadtools.Forms.DocumentWriters.RtfDocumentOptions

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
