If you are getting a raster image, then I would look into using JAI
or the equivalent to crop/clip stuff outside your viewable area and
then place it into the PDF.
If you are working with combined text, vector, raster - then iText
isn't going to help you. There are, however, commercial solutions
that can address that problem.

Hi
is there a way to have the data in the not visible area really
clipped in terms of deleted? I'm adding a existing pdf-file with
the follow lines:
URL PdfUrl = (URL) aMap.get("url");
PdfReader reader = new PdfReader(PdfUrl);
Image myImg = Image.getInstance(tp);
myImg.scaleAbsolute(width, height);
myImg.setAbsolutePosition(marginX, marginY);
cb.addImage(myImg);
The remote pdf is also generated with itext. Sometimes it is really
big (~1.5 Mbyte) when you'd expect something around 300 KByte. The
software (geoserver) is delivering only whole features (geodata),
so you see only the requested part of the features but in the
invisible part of the pdf document is the whole object (e.g. a
really huge street object). This behaviour makes the pdf
unnecessary big.
Thanks.
