Hi,

yes... with image.
Here's a normal sample from the kb:

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;

Try it ... then you'll know it.
Post the code if it works... then we'll know it, too ;-)
