> I'd like to add a watermark to a PDF and have the following code:
> {code:java}
> PDDocument pdfDocument = PDDocument.load(new
> PDDocument pdfCopy = Pdf.addWatermark(pdfDocument);
>
> pdfDocument.close();
> pdfCopy.close();
> ....
> public static PDDocument addWatermark(PDDocument document) {
> try {
> HashMap<Integer, String> overlayGuide = new HashMap<Integer,
> String>();
>
> for(int no = 0; no < document.getNumberOfPages(); no++){
> overlayGuide.put(no +1, "C:\\Software\\watermark.pdf");
> }
>
> Overlay overlay = new Overlay();
> overlay.setInputPDF(document);
> overlay.setOverlayPosition(Overlay.Position.FOREGROUND);
>
> PDDocument result = overlay.overlay(overlayGuide);
>
> document.close();
> overlay.close();

> return result;

> } catch (Exception e) {
