Please post a code fragment that replicates the behavior your seeing.
Paulo has suggested you look at the Crop Box coordinates, which is good advice.
I suspect you'll find that the lower-left-hand corner (llc) of your PDF is not
at (0, 0) in PDF document space.
FYI, some of the iText convenience methods for width and height are based on
the llc being a (0, 0). If the llc is elsewhere, you'd do better by using the
methods that return results that are consistent with your situation, e.g., from
actual working code:
//mods for shifted origin, 3Oct2007
float llx, lly, urx, ury;
llx = SFx*pageSize.left();
lly = SFy*pageSize.bottom();
urx = SFx*pageSize.right();
ury = SFy*pageSize.top();
Now, without seeing your code, or the PDF with which you're having problems, or
knowing the version of Reader you're using, I'm just gueswsing the problem
you're having might be similar to the problem I experienced for which the above
methods provided a correct solution.
Please let us know if you need more, providing the aformentioned missing
information, if this response doesn't help you solve your problem.
BTW, the above information is definitely findable in the documentation and
examples.
Do you have the book? If not, it's highly recommended, if you're serious about
working with iText.
Best regards,
Bill Segraves
