Hi,
I intentionally mentioned that those are 64bit numbers. See the
Architectural Limits section of the PDF specification, notably:
Table C.1 describes the minimum architectural limits that should be
accommodated by conforming readers running on 32-bit machines.
Because conforming readers may be subject to these limits,
conforming writers producing PDF files should remain within them.
But I understand that the idea behind this report is to make the code
more robust and error/evil-prone.
Bye,
zyx
