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

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

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

Currently, the XpsDocumentOptions class contains no extra options.

This format requires .NET framework 3.0.
