This is the first time I've worked with itextsharp. I'm maintaining existing code so most of the work was already done for me. I have a question on how to do this enhancement.
My code currently dynamically generates a PDF with n-pages. I want to remove the code that generates the nth page and instead pull in a static PDF document. So in other words I have these variable data that I'm creating cells and tables from, but my last page is non-changing and we want to move from dynamically generating it to just pulling it in from an existing file.
I think this is the relevant code you would want to see:
BuildPDF() does all the work with the variably-occurring pages and ends with this:
It is CreateFooterPage() that I want to change to just open an existing pdf, read it into some object and append it to this.PDFDocument. I know I am way oversimplifying it but simply stated, that's it.
I'm not sure what would get the right hits in google. Do you know where I can start to find documentation on this?

Code:
// This method builds the PDF
byte[] bytes = (byte[])BuildPdf(startDT, endDT);
//Clear out the response
Response.Clear();
Response.ClearContent();
//clear out the headers
Response.ClearHeaders();
//add the new PDF headers
int length = bytes.Length;
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", length.ToString());
Response.AppendHeader("Content-Disposition", "inline; filename=MyPDF.PDF");
//stream the data to the browser
Response.BinaryWrite(bytes);
// changed to flush/close vs. end for F5
Response.Flush();
Response.Close();
//Response.End();Code:
// Add footer page
CreateFooterPage();
// Close the document to complete it
PDFDocument.Close();
stream.Flush();
stream.Position = 0;
//Clean up.
this.PDFDocument = null;
byte[] data = new byte[stream.Length];
stream.Read(data, 0, data.Length);
stream.Close();
return data;I'm not sure what would get the right hits in google. Do you know where I can start to find documentation on this?
