Hi Wahaj,
to apply certified signature you can write (for example):
...
PdfStamper stamper = PdfStamper.createSignature(reader, fout,
'\0');
PdfSignatureAppearance sap = stamper.getSignatureAppearance();
sap.setCertified(2);
sap.setVisibleSignature(new com.lowagie.text.Rectangle(340, 400, 490,
500), 1, null);
for approval signature you will write:
PdfStamper stamper = PdfStamper.createSignature(reader, fout,
'\0', null, true);
PdfSignatureAppearance sap = stamper.getSignatureAppearance();
sap.setCertified(0);
sap.setVisibleSignature("Signature**");
** Empty fieldname
