what you suggest is to sign with pfx file

i just want to add "handwrite" signature (with the mouse) in a PDF form.
or just PDF (with no form).
some thing like annotation but when the user add the BMP or sign with the mouse,
save the file and not let any one touch the "signature"

that seem working.

procedure TfrmDemo.Button1Click(Sender: TObject);
var
  SignProcessID: Integer;
  FldIndx : integer;
  ImgIndex : integer;
  Rslt : integer;
  tmpJpg : TJpegGraphic;
  Stream  : TMemoryStream;
begin

  if Not Assigned(ViewPrintQP) then
  begin
    ViewPrintQP := TDebenuPDFLibrary.Create;
    ViewPrintQP.UnlockKey(edtLicenseKey.Text);
  end;

  Rslt := ViewPrintQP.LoadFromFile('c:\aa\QuickPDF.pdf', '');
  if rslt <> 1 then
    beep;

(*
  Rslt := ViewPrintQP.AddStampAnnotationFromImage(50,50,50,50,'c:\aa\logo-2.jpg','mazluta','hanibaal',0,0,0,0);
  if rslt <> 1 then
    beep;
  Rslt := ViewPrintQP.SaveToFile('c:\aa\Quick2.pdf');
  if rslt <> 1 then
    beep;
*)

  FldIndx := ViewPrintQP.NewFormField('mazluta',6);

  ViewPrintQP.SetFormFieldBounds(FldIndx, 10, 400, 100, 100);
  ViewPrintQP.SetFormFieldHighlightMode(FldIndx, 2);

  tmpJpg := TJpegGraphic.Create;
  Try
    tmpJpg.LoadFromFile('c:\aa\logo-2.jpg');
    Stream  := TMemoryStream.Create;
    Try
      tmpJpg.SaveToStream(Stream);
      ImgIndex := ViewPrintQP.AddImageFromStream(Stream,0);
    Finally
      FreeAndNil(Stream);
    End;
  Finally
    FreeAndNil(tmpJpg);
  End;

  Rslt := ViewPrintQP.SelectImage(ImgIndex);
  if rslt <> 1 then
    beep;

  Rslt := ViewPrintQP.SetFormFieldSignatureImage(FldIndx,ImgIndex,0);
  if rslt <> 1 then
    beep;

  ViewPrintQP.SetNeedAppearances(0);
  ViewPrintQP.UpdateAndFlattenFormField(FldIndx);

  Rslt := ViewPrintQP.SaveToFile('c:\aa\Quick2.pdf');
  if rslt <> 1 then
    beep;
  ViewPrintQP.Free;
end;
