Thank you. I do have the book, and I did try this, and it didn't work
(the annotation still shows up on AR 8), just like the code I supplied
in my first mail didn't (see below).
That was the whole reason I posted a question on this forum.
======================================================
PdfAnnotation pdfAnnotation = PdfAnnotation.createText(
stamper.getWriter(), new Rectangle(1, 1, 1, 1),
"Comment", false, null);
PdfAnnotation.FLAGS_HIDDEN);
pdfAnnotation.put(PdfName.F, new PdfNumber(PdfAnnotation.FLAGS_READONLY
| PdfAnnotation.FLAGS_NOVIEW | PdfAnnotation.FLAGS_INVISIBLE |
PdfAnnotation.FLAGS_HIDDEN));
stamper.addAnnotation(pdfAnnotation, 1);
======================================================
P.S. There's a problem with my mail client. Apologies if you guys get a
double post.
