I want to watermark a pdf file without creating another pdf file?

ITextSharp doesn't support "in-place editing" of files, only reading existing files and creating new files. The problem is that it would have to write to something that is being written to which could be very problematic.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
