Hi, OK, took several days working on this, but I can not find out anything, how can I get those differences? I've analysed the binary of this document http://www.nabble.com/file/p23704652/textoF2IMod.pdf textoF2IMod.pdf , but the object with the difference (70 0) returns null with the itext (reader.refObj[70]).
To sum it all up, I need to know whether there are differences between one signature and the other. I'd be very grateful if you could tell me the way to get that result with iText. Thanks Michael for the answers. mkl wrote: > > > OscarP wrote: >> >> Hi again, >> >> I want to compare the contents of two revisions of the same signed PDF, >> without considering the signature fields.
