Question

What I am doing is to generate a pdf booklet from database. I need go generate a content table with page numbers. E.g there are two chapters with page number like:

=============================

Content table

Chapter 1 —– 3

Chapter 2 —– 17

=============================

The text “Chapter 1 —– ” is normal paragraph. But the page number “3” has to be produced using PdfTemplate because it can only be known later. But the pdfTemplate is absolutely positioned. How can I know where to position the PdfTemplate? Am I right on this ? How could I figure this out or should I use other methods?

Answer 1

I’ve extracted a bit of code to get you on your way.. This code allows you to place text anywhere on a page using an x and y. You may actually want to use iTextSharp’s built in paragraph and margin support, but this will be useful, just needs converting to C#

Dim stamper As PdfStamper
Dim templateReader As PdfReader = New PdfReader(yourFileName)
Dim currentPage As PdfImportedPage = stamper.GetImportedPage(templateReader, 1)    
stamper.InsertPage(1, PageSize.A4)
Dim cb As PdfContentByte = stamper.GetOverContent(1)
cb.AddTemplate(currentPage, 0, 0)

Look this next bit with each element you want to add..

cb.BeginText()
cb.SetFontAndSize(bf, 12)
cb.SetColorFill(color) 'create a color object to represent the colour you want
cb.ShowTextAligned(1, "Content Table", x, y, 0) 'pass in the x & y of the element
cb.EndText()
