How to copy form fields with PdfWriter not PdfCopy in iTextSharp

I would like to merge two PDF files (only selected pages) and add custom headers and footers to them.

Therefore I do not use PdfCopy that simply copies the page without altering it. I use the PdfWriter.

The problem is I do not know how to copy AcroFields, Acroforms, Annotations and everything else except content with the PdfWriter.

Do you know how to do this?

You want to use the GetImportedPage method of the PdfWriter class. This copies everything into a PdfImportedPage that you can then use.

PdfReader pdfReader = new PdfReader(originalFile);
PdfImportedPage importedPage = pdfWriter.GetImportedPage(pdfReader, pageNumber);

As an example, you can place the previous code in the OnOpenDocument event of a PdfPageEventHelper and then in the OnEndPage event you can use the DirectContentUnder object of the PdfWriter to place the entire page underneath your current page.

pdfWriter.DirectContentUnder.AddTemplate(importedPage, 0, 0);
