Remarks

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

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

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

The TextDocumentOptions class contains the following properties:

Property	Description
DocumentType	The type of the Text document (ANSI, UTF8 or UNICODE).
Formatted	To control whether the output file will be just a flow of text or try to maintain almost the same shape of original page (i.e. margins and lines between paragraphs using spaces).
AddPageBreak	Add an optional marker between pages in the resulting text file.
AddPageNumber	Print the page numbers in the resulting text file.

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

Example

This example will create a new text file using the various supported options.
