Hi, i try to implement the following steps: 1) reading a signed pdf 2) adding a javascript code to the pdf and 3) printing the pdf to the default printer.
... try { PdfReader reader = new PdfReader(pdfByteArray); //pdfByteArray represents the content of pdf file PdfStamper stamper = new PdfStamper(reader, outputStream); stamper.addJavaScript("this.print(false);"); stamper.close(); } catch (Exception e) {...} ... After executing the java code the signed document is printed but the signature is not valid. If i don't add the javascript code the pdf is displayed by acrobat reader within the browser but the signature is also invalid! (Error message: byte range of the signature is not valid.) My questions: 1) How is it possible to read a signed pdf document without destroying the signature? 2) Is there a possibility to add javascript code so that the signature keeps valid?
