Is it possible to compare 2 pdf files and highlight their differences in another pdf file using php (TCPDF)?.  Both files will most likely have tables and some complex structures.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Unfortunately, I was not able to do it. I had to refactor a module so that the source html text was compared before converting into pdf.
I believe it cannot be done accurately using a pdf file itself as it seems not to hold any table structure at all.
