I tried the concatPDFs code. It concatenates two files OK. But, it does not copy the signatures that were in the files. It also does not copy text data fields.

You could reduce the number of lines by using PdfStamper class.

PdfReader pdfReader = new PdfReader(fileDialog.FileName);
FileOutputStream fout = new FileOutputStream(“C:\\output1.pdf”);
PdfStamper splitter = new PdfStamper(pdfReader, fout);
pdfReader.SelectPages(“1 – 10″);
splitter.Close();
pdfReader.Close();

Does anybody have any examples for splitting a PDF at bookmarks that exist at a level 2? The code provided by Goblin_Queen works great for level 1 bookmarks, but I’m not quite sure how to expand that to level 2 bookmarks as the resulting hashmap for the “Kids” do not contain page information.

HashMap bm = bookmarks.get(i);
List kids = (List) bm.get(“Kids”);

The kids hashmap does not have the “Page” defined.

Hey

I have used your code for merging few pdf files but I still have a problem to merge files that carry different sizes!
I have try to had a command to set the page size

document.newPage();
pageOfCurrentReaderPDF++;
currentPageNumber++;
document.setPageSize(pdfReader.getPageSize(pageOfCurrentReaderPDF));

Thanks, for the helpful code!

Dimitri asked:

“Viral : If you already found the script for splitting pdfs by page size, it would be VERY handy”

I found the answer here:

http://java-x.blogspot.com/2006/11/merge-pdf-files-with-itext.html#comment-3167256311373072651

document.setPageSize(pdfReader.getPageSizeWithRotation(pageOfCurrentReaderPDF));
document.newPage();

I.e., immediately before creating a new page, set the page size to the page size (and orientation) of the page you are reading in. The only issue to be aware of is the PDF has to be (I believe) version 1.5 or higher. You’ll get errors trying to open PDFs saved as 1.4.

pdfWriter.setPdfVersion(PdfWriter.PDF_VERSION_1_5);
