How to add footer in existing pdf -iTextSharp

Question

I have been trying to figure out if it is possible to add a footer to an existing PDF document. Every example I have seen is for adding a footer to a document that has just been created using PDFWriter as opposed to getting a document using PDFReader and then adding a footer to it. Does anyone know of a way that a footer can be added to an existing PDF? Thanks.

It seems that this question has been asked in many different forums. I googled and find the most proper one for you in which no external PDF creator or PDF reader SDK is required. Hope it can help you a little.  Have a look at chapter 6 of iText in Action 2nd edition especially at subsection 6.4.1: Concatenating and splitting PDF documents. Listing 6.22 ConcatenateStamp.java  shows you how you should create a PDF from copies of pages (in your case: all pages) of multiple other PDFs; the sample additionally adds a new Page X of Y footer; this demonstrates how you can add content at given positions on the pages while merging the source files.

Hi Rahul Maybe it cannot be implemented directly here is a kind of method to help draw the footer in existing pdf file. Of course it need to use another component but not iTextSharp it's Spire.PDF. Try the code below private static void DrawPageNumber(PdfPageCollection section PdfMargins margin int startNumber int pageCount) { foreach (PdfPageBase page in section) { page.Canvas.SetTransparency(0.5f); PdfBrush brush = PdfBrushes.Black; PdfPen pen = new PdfPen(brush 0.75f); PdfTrueTypeFont font = new PdfTrueTypeFont(new Font(Arial 10f FontStyle.Bold) true); PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Right); format.MeasureTrailingSpaces = true; float space = font.Height * 0.75f; float x = margin.Left; float width = page.Canvas.ClientSize.Width - margin.Left - margin.Right; float y = page.Canvas.ClientSize.Height - margin.Bottom + space; page.Canvas.DrawLine(pen x y x + width y); y = y + 1; String numberLabel = String.Format({0} of {1} startNumber++ pageCount); page.Canvas.DrawString(numberLabel font brush x + width y format); page.Canvas.SetTransparency(1); } } article: http://www.e-iceblue.com/Knowledgebase/Spire.PDF/Program-Guide/Add-PDF-Footer.html

PdfContentByte underContent = pdfStamper.getUnderContent(i); PdfContentByte overContent = pdfStamper.getOverContent(i); PdfPTable footer = new PdfPTable( 2 ); footer.setTotalWidth( 1000 ); footer.getDefaultCell().setHorizontalAlignment(Element.ALIGN_LEFT); footer.addCell( new Phrase( Footer First Page )); footer.addCell( new Phrase( Footer Prev Page )); footer.addCell( new Phrase( Footer Next Page )); footer.addCell( new Phrase( Footer Last Page )); PdfPTable header = new PdfPTable( 3 ); header.setTotalWidth( 1000 ); header.getDefaultCell().setHorizontalAlignment(Element.ALIGN_LEFT); header.addCell( new Phrase( Header Page )); header.addCell( new Phrase( Header Page )); header.addCell( new Phrase( Header Page )); Document document = underContent.getPdfDocument(); Document overDocument = overContent.getPdfDocument(); header.writeSelectedRows( 0  - 1  (overDocument.right() - overDocument.left() - 300 ) / 2 + overDocument.leftMargin() overDocument.top() - 10  overContent); footer.writeSelectedRows( 0  - 1  (document.right() - document.left() - 300 ) / 2 + document.leftMargin() document.bottom() - 10  underContent); Thanks & Regards Praveen Nelge
