        using (PdfDocument pdfDocument = PresentationToPdfConverter.Convert(pptxDoc))
        {
            //Save the converted PDF document to MemoryStream.
            MemoryStream pdfStream = new MemoryStream();
            pdfDocument.Save(pdfStream);
            pdfStream.Position = 0;
            //Create FileStream to save the PDF file.
            using (FileStream outputStream = new FileStream("Sample.pdf", FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
            {
                //Saves the PDF file.
