Is there a straight forward way to append one PDF doc to another using iTextSharp?

Question

I\'ve scoured the Web looking for examples on how to do this. I\'ve found a few that seem to be a little more involved then they need to be. So my question is, using iTextShar

Answer 1

Yes. I've seen a class called PdfManipulation posted in an iText forum. Using that class would involve a third file though.

The class is originally in VB.Net. I downloaded it from a post on vbforums.com. Apparently though, it doesn't have the merge files function, so I wrote one based on the code in that class.

This was written on a machine without iTextSharp. This might have bugs. I'm not even sure if page numbers are 0-based or 1-based. But give it a shot.

public static void MergePdfFiles(IEnumerable files, string output) {
    iTextSharp.text.Document doc;
    iTextSharp.text.pdf.PdfCopy pdfCpy;

    doc = new iTextSharp.text.Document();
    pdfCpy = new iTextSharp.text.pdf.PdfCopy(doc, new System.IO.FileStream(output, System.IO.FileMode.Create));
    doc.Open();

    foreach (string file in files) {
        // initialize a reader
        iTextSharp.text.pdf.PdfReader reader = new iTextSharp.text.pdf.PdfReader(file);
        int pageCount = reader.NumberOfPages;

        // set page size for the documents
        doc.SetPageSize(reader.GetPageSizeWithRotation(1));

        for (int pageNum = 1; pageNum <= pageCount; pageNum++) {
            iTextSharp.text.pdf.PdfImportedPage page = pdfCpy.GetImportedPage(reader, pageNum);
            pdfCpy.AddPage(page);
        }

        reader.Close();
    }

    doc.Close();
}
