Perl how to compare two pdf files line by line
Hi Experts,

Would really appreciate if anyone can guide me how to compare two pdf files line by line and report the difference to another file.

PDF files don't exactly have 'lines' per se, they're full of printer commands. That's what makes them such a hassle to create and edit.

If the contents are laid out in very specific ways it might be possible.

First extract as text, then do the diff
Comes to mind: pdf2txt

and then there may be a Perl script that does the job of

diff. (See GNU tools for Windows if you are running MSWindows)
