Hello,
Thanks all for your inputs.

Vadim, I'll give it a try. I tried Inet PDF comparison software and it
seems to do the job but that's an extra licence (and the IT team will
say:"why do you need another tool, you already have Acrobat?!").

Trevor, I will also look at the fonts. However, for the layers, my
understanding was that XEP does not support PDF layers so I'm not sure
what I should look at?

Here are the two main use cases for me to compare PDF files (both
generated by XEP):
a) I have project requirements (unique identifiers) set up as conditional
text in my source files and I generate two PDFs from the same ditamap: one
with the requirements, one without. The requirements are traced and
verified/tested in the PDF with requirements (!) but the "official" PDF
(that we give to our customers) is the one without the requirements. The
company Quality team wants me to prove that the only differences between
the two PDFs are the requirements but that the rest of the content is
exactly the same.
b) After the initial release of the documents, they are regularly revised.
In this case, comparisons are made to make sure only the content that
needed corrections had been modified and that we didn't create
"regressions".
Regarding the XML temp file used to generate the PDF, I suggested the
program manager to use it in his traceability tool (Reqtify) but it
doesn't work. I don't know if it's a setup issue or a parser issue
(Reqtify does analyze some "simple" xml files but not the one from my
ditamap). But even if it works, it doesn't answer all my needs.

Thanks & regards,

I'd recommend trying out DiffPDF as well to see if it can compare.

Perhaps give us a little background on what you are looking to do and
possibly there are other (even better) solutions.
For example, on a recent project another company was looking for
identifying differences between minor composition runs of RenderX.
We implemented a compare not of the PDFs, but of the XEP Intermediate XML
format that produces the PDF. This is a much more rich comparison, not
relying on a tool to attempt to interpret a final form document.

Now, I am not sure you are comparing XEP PDF to XEP PDF or ?

I got your point Kevin. I doubt they would help me because their tool does
work with some PDFs (based on various forums, it seems that they've had
issues with this tool for a long time and new versions do not solve
anything). I was wondering if there was anything I could do to make it
work for my PDFs. My other option is to compare the PDFs with a tool other
than Acrobat.

IMHO you asking the wrong company a question. You should ask Adobe why
their tool fails on comparing PDFs as that is supposedly what the tool
does.

Hello XEP community,

I'm using XEP to generate PDF output from DITA source files. When
comparing two PDF files generated with XEP in Adobe Acrobat Pro, the
comparison fails. When comparing two files generated with Framemaker, the
comparison runs Ok. Is there anything in XEP that I could modify to make
sure we can compare PDFs? I'm using XEP (via Oxygen) with the default
settings so far.

Thanks!
