问题 In short, I'm having issues specifically "flattening" stamp comments in PDF's while using Itextsharp. The effect I'm looking for is identical to what you get when you "print to PDF" from Acrobat (the stamp can no longer be moved/edited/etc. but you can still select any text it might have).

I've successfully used the

问题 I am trying to fill out a pdf form and the form could have multiple pages of the same form, so instead of writing each one to disk I want to create one pdf document in memory with all the pages.

问题 I have tried this now and its not working. form.GenerateAppearances = true; I merge my 2 documents and then save it. Then I open it again to populate all the fields. It says all the Acrofields keys are gone but when I open it in Nitro pro its there. Why can't I see them in code?

问题 I'm trying to offset the position of an image within a table-cell in ITextSharp. Below is some pseudo-code outlining some of my attempts, none of which seem to affect the positioning of the image.
