When exporting a RadFixedDocument, which contains a signature added with PdfProcessing a NotSupportedException is thrown: 'Stream does not support reading.'

Resolution: When exporting a digitally signed document a stream that allows both reading and writing should be passed to the PdfFormatProvider.

Example:

Stream outputStream = new FileStream("path", FileMode.OpenOrCreate, FileAccess.ReadWrite)
