Hi,

I am generating 2 documents with iText. I want to test, if the documents
are identical. (Background: I'm doing a refactoring and want to test if
the functionality remains the same.)

The documents look identical, but "diff" says that they are not.
Unfortunately, it doesn't tell me *what* differences are there, because
the files are binary.

My first idea was that there is a timestamp in the PDF that is not
displayed but of course is a difference.

I tried to filter the PDFs using "hexdump -C", but when comparing the
results with diff, it is obvious that there are *many* differences (or
perhaps it is only a small "offset-difference" that diff does not
realize correctly).

Anyhow, that kind of comparison does not work.

So, my question is: (How) can i tell iText to save a document
"uncompressed", so that the differeneces are more obvious and readable?

Or is there a completely different approch to my problem rather than
extract the ASCII out of the PDF at the end?

Ciao,
Ingo
