Hi all,
this is my first post in the forum and i hope someone can help me.
I'm developing a tool in Objective-C which produce pdf digital signature in the PADES format. The signature is added as as revision, redefining/creating the opportune objects (Acroform, annot, SigField etc.). The original file is (One_Sign.pdf) signed using Acrobat standard 9.0 The signature seems ok but Adobe reader invalidate the first signature telling that de document has modification between the signature (1 Page(s) Deleted 1 Page(s) Added)... obiusly i didn't any modification Can some one help me to understand this error? Maybe the original file is usig Cross-references stream instead of classic xref table while in the revision i use classic xref table? Regards http://dl.dropbox.com/u/3995257/PDF/One_Sign.pdf
The output file is (Two_Sign.pdf) signed using my tool
