All the supported document formats and the corresponding format providers are listed in the Formats and Conversion section.

In order to use the PdfFormatProvider of WordsProcessing, you should add a reference to the Telerik.Windows.Documents.Flow.FormatProviders.Pdf assembly. For the full list of dependencies required by WordsProcessing, check the Getting Started topic.

The PdfFormatProvider class of WordsProcessing resides in the Telerik.Windows.Documents.Flow.FormatProviders.Pdf namespace. For more information on how to work with this provider, please read this topic.

    }

    Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider pdfProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();

    // Export the document. The different overloads enables you to export to a byte[] or to a Stream.
