Example 4: Stamp a PDF file with a PDF overlay (Delphi)  

uses ComObj;

procedure TForm1.Button1Click(Sender: TObject);
  NVstamp : Variant;
  indx : Integer;
  retVal : Integer;
  NVstamp := CreateOLEObject('PDFstamp.Neevia');

  indx := NVstamp.CreateNewStamp;
  NVstamp.Stamps[indx].StampType := 3;
  NVStamp.Stamps[indx].Name := 'Stamp1';
  NVStamp.Stamps[indx].PDFOverlayFile := 'c:\overlay.pdf';
  NVStamp.Stamps[indx].X := 'center';
  NVStamp.Stamps[indx].Y := 'center';
  NVStamp.Stamps[indx].PlaceAs := 1;

  retVal := NVStamp.StampPDF('c:\in.pdf', 'c:\out.pdf');

  if retVal <> 0 then
    Application.MessageBox(PChar('Error code=' + IntToStr(retVal)),'',0)


I was looking for a product that could place watermarks on very large PDF files (some of them over 30 thousand pages) in as less time as possible. After testing many tools I found Neevia PDFstamp. It did the job!
