The code as it is processes correctly the crop box. You are probably looking
at something else. Why don't you create a document with iText or Acrobat
with a crop box with some marking around the limits to see there's really a
margin problem? Or use the file http://www.jahn.org/pdf3/cmyk.pdf that has
crop marks to see what happens.

Subject: [iText-questions] margin problem
Hi Paulo and all,
I study the code that Paulo send me about a week ago about the crop box
effect. And I still having the extra margin effect on the copied
document.
I still not really sure if it's the crop box that causing the problem.
Here is the problem that I��m having. I'm writing a program that copy
the
exist PDF file into a new PDF file and add a text on top of it. And the
new
PDF file has extra margin than the original one (about twice as big).
And I
test it with different pdf file, and I notice for some pdf file, it��s
ok,
and for other is not. So, I��m not sure why and how I should fix it.
Below
is my code, please help me out if anyone has any idea.
P.S. The PDF file that I used to test my program is JRUN spec. That's
the
file that gave me extra margin. I create couple PDF file myself, those
copy
was copy good with exact same margin. Don't know what's the different.
Thanks once again,
Waymon
