Changing document properties of pdf

Hi,

I have investigated on the problem and I have found out, that I can sign the created document in Acrobat Standard 6 but not in Acrobat Reader 7 or Acrobat Reader 6.

Is there something special that I have to do or set a parameter in order to can sign the document in Acrobat Reader?

The method I used for creating an empty signature filed is the one that I have found in the mailing list.

PdfReader pdf = new PdfReader("c:/test.pdf");

PdfStamper stp = new PdfStamper(pdf, new FileOutputStream("c:/test_sign.pdf"));

PdfFormField sig = PdfFormField.createSignature(stp.getWriter());

sig.setWidget(new Rectangle(100, 100, 200, 200), null);

sig.setFlags(PdfAnnotation.FLAGS_PRINT);

sig.put(PdfName.DA, new PdfString("/Helv 0 Tf 0 g"));

sig.setFieldName("Signature1");

//sig.setPage(1);

//stp.addAnnotation(sig, 1);

sig.setPage(pdf.getNumberOfPages());

stp.addAnnotation(sig, pdf.getNumberOfPages());

stp.close();

Regards

Paul

Subject: [iText-questions] Changing document properties of pdf

Hi,

I have added an empty signature field into a existing pdf document.

But I’m not able to sign the document because in the Document Properties the Sign is set to Not Allowed.

The PDF Version of the file is 1.3 (Acrobat 4.x).

Is there a possibility to manipulate this flag with iText?

Regards

Paul
