[RESOLVED] Generate PDF from binary?

I'm trying to create a PDF file from binary data retrieved from a webservice. The data is successfully retrieved but it is displayed on the page in binary instead of being converted into a PDF file. I am not sure how to make the data appear in the form of a PDF file instead of just as a string. I tried using iTextSharp to create a PDF but am not sure how to get the PDFWriter to write the data from the BinaryWriter??!

Code:

---

        protected void GenerateArchivePDF(int value)
        {
            try {
                // Retrieve data
                PDFbinary = archives[value].PDFBitArray;

                // Create a new temp file called "test.dat" which contains data imported from webservice
                FileStream readStream = File.Create(Server.MapPath("test.dat"));
                BinaryWriter binaryWriter = new BinaryWriter(readStream);

                // Write the binary data to the file
                binaryWriter.Write(PDFbinary);
                binaryWriter.Close();
                readStream.Close();

                // Create a new PDF document
                doc = new Document(PageSize.A4, 80, 50, 30, 65);
                FileStream pdfStream = new FileStream("~/Beurteilungsbogen.pdf", FileMode.Create);
                PdfWriter pdfWriter = PdfWriter.GetInstance(doc, pdfStream);

                // Import data from newly created file named "test.dat"
                stream = File.OpenRead(Server.MapPath("test.dat"));
                binaryReader = new BinaryReader(stream);

                // Read from file - INSTEAD OF WRITING ON PAGE SHOULD WRITE IN PDF!
                Response.Write(binaryReader.ReadInt32());
                //pdfWriter.Add(Response.Write(binaryReader.ReadInt32())); // trying to write to PDF!
         
                // Close
                binaryReader.Close();
                stream.Close();
            }
            catch (DocumentException de)
            {
                errorPage.DisplayErrorMsg(de.Message);
            }
            catch (IOException ioe)
            {
                errorPage.DisplayErrorMsg(ioe.Message);
            }
            finally
            {
                doc.Close();
                Response.Redirect("~/Beurteilungsbogen.pdf");
            }

If the binary data is the PDF (which seems to), than you can use following code

Code:

---

byte[] buffer = ... // here is conversion from PDFbinary; sorry I omit it
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = application/pdf;
Response.AddHeader("Content-Disposition", "attachment;filename=yourfile.pdf");
Response.AddHeader("Content-Length", buffer.Length.ToString());
Response.OutputStream.Write(buffer, 0, buffer.Length);
Response.Flush();
Response.End();

---

Yes it is. So it's not possible to use my code then? Instead of using a byte[] buffer (as I originally wanted to do) I imported binary data in the form of an integer and then wrote it to a new file using the BinaryWriter. I then tried to read this file using the BinaryReader but I dont know how to make this appear in the PDF I created??

I have been using ZetPDF for a while now for generating PDF from the library and it is been awesome. ZetPDF is a .net SDK for adding PDF render and print support in .net applications. It is designed to solve most developer’s needs with regards to PDF rendering.
