I am trying to modify a customer's code to export specific pages of a document to a byte array.  I have a document with two pages, and to try to export the second page, I do the following:

            ILFConnection lfConnection = m_Conn.Database.CurrentConnection;
            DocumentExporter documentExporter = new DocumentExporterClass();
            ILFEntry lfEntry =m_Conn.GetEntryFromCache(laserficheObject.EntryID, false);
            LFDocument lfDocument = (LFDocument)lfEntry;
            LFDocumentPages lfDocPages = lfDocument.Pages;
            lfDocPages.MarkPage(lfDocPages.Item[1]);
            documentExporter.AddSourcePages(lfDocPages.Item[1]);
            documentExporter.Format = Document_Format.DOCUMENT_FORMAT_JPEG;
            //documentExporter.VerifyImageChecksum = true;
            byte[] bytes = (byte[])documentExporter.Export();

But I still get only page 1!  By marking page[1] and adding that as source page for the exporter, shouldn't I be getting page 2 exported (assuming this is zero indexed and page 1 is Item[0] and page 2 is Item[1]).
