Add-on for FPDI to Support Compression Technique and Encrypted or Protected PDFs
By default FPDI can "only" handle PDF documents with a normal cross-reference which was the default way to store object offsets in a PDF document up to PDF version 1.4. Beginning with PDF version 1.5 there were new compression features introduced which involve internal structure changes how a PDF document can be created.
With this seperate parser, as a commercial add-on, you're up to date and FPDI will be able to handle PDF documents which uses this compression feature without a problem.
As of version 2.1 the add-on will also allow FPDI to import pages of encrypted or protected PDF documents. Check out the manual for more details.
It is also able to repair common faulty PDF structures at runtime.
