Sorry about this rather long posting! I was
trying to do some kind of PDF annotation and stamping (e.g. the "Received"
chop) to simulate the similar functions that can be performed through Adobe
Acrobat. I seem to be able to add some kind of
annotation to the PDF file, but the result doesn't seem to be fully compatible
with the different acrobat readers.
For example the Text
annotaiton that I've added cannot be printed to the printer, but can be viewed
on screen; the stamp annotation that I've added would depends on the name of
the stamp being used does not "stick" with the PDF file and behaves
differently from Acrobat Reader 5.0 and 6.
I would like to look for some pointers on if I am
doing the annotation the right way by using the PDFStamper, or that I need to
use other iText classes to do the annotation? The code segements are
included below for your information:
For Text/Note Annotation:
// we create a reader for a
certain document and get page
count
PdfReader reader = new
PdfReader(inFile);
int n =
reader.getNumberOfPages();
// step 2: open a
PDFStamper
PdfStamper stamp = new PdfStamper(reader, new
FileOutputStream(outFile));
// step 3: we add the
annotation
int i =
0;
while (i < n)
{
i++;
PdfImportedPage page =
stamp.getImportedPage(reader,
i);
if (i == 1)
{
stamp.addAnnotation(PdfAnnotation.createText(
stamp.getWriter(), new Rectangle(topX, topY, bottomX, bottomY),
author, text, false, "Note"),
i);
}
stamp.close();
For Image Annotation:
The call to PdfAnnotation.createText() is
replaced by PdfAnnotation.createStamp() and uses the StampName such as
"Approved" or "As Is" in Adobe 5, and "#DApproved" in Acrobat Reader
6.
Thanks for your kind help!
Regards
