How to change the author name for comments?

Does anyone have a script which will change the name of the author whenever any markup such as underlining, highlighting, etc, is applied? You can do this manually through the properties box, but this is time consuming and difficult.

Take a look at the code below. We take a PDF with annotations created by "iText" and turn it into a PDF with annotations created by "Bruno Lowagie".

The code is really simple: we loop over the annotations of a page and change the title (if it equals to "iText"). We use PdfDocument to persist the changed PDF.

public void manipulatePdf(String src, String dest) throws IOException {
    PdfDocument pdfDoc = new PdfDocument(new PdfReader(src), new PdfWriter(dest));
    List annots = pdfDoc.getFirstPage().getAnnotations();
    if (annots != null) {
        for (PdfAnnotation a : annots) {
            if (a.getTitle() != null && a.getTitle().toString().equals("iText"))
                a.setTitle(new PdfString("Bruno Lowagie"));
