Hello! As promised an example for the issue. BTW, while creating the example I found out that the issue only comes up if the document in question has more than one page (in addition to the streams used in page contents arrays multiple times, of course) --- this is due to eliminateSharedStreams() immediately returning for single page documents.
Sample file: http://old.nabble.com/file/p26756669/sample.pdf sample.pdf (Included verbatim at the end of this message.) Code fragment: PdfReader reader = new PdfReader(new URL("http://old.nabble.com/file/t1363360/sample.pdf";)); PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(new File(sample.out.pdf")), '\0', true); stamper.addSignature("sig", 1, 100, 100, 200, 200); stamper.close(); This replaces the /Contents array of the first page: /Contents [4 0 R 4 0 R 5 0 R 5 0 R] by /Contents[4 0 R 7 0 R 5 0 R 8 0 R] without including any objects 7 0 obj or 8 0 obj.
