Getting error while merging PDF #30

Getting below mentioned error while merging pdf files

This PDF document probably uses a compression technique which is not supported by the free parser shipped with FPDI. (See https:\/\/www.setasign.com\/fpdi-pdf-parser for more details)

Need input on this

I post a late response here because I got the same error, maybe I can help someone else. This is what i found on https://www.setasign.com/support/faq/fpdi/error-document-compression-technique-not-supported/#question-89:

Error: "This PDF document probably uses a compression technique which is not supported by the free parser shipped with FPDI."

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.

We offer a commercial addon which enables FPDI to handle documents that uses these compression features.

Alternatively the document you're trying to import has to be resaved without the use of compressed cross-reference streams and objects by an external programm (e.g. by lowering the PDF version to 1.4).

Does this package work together with the commercial addon? It doesn't do it out of the box in mine. installed pdf-parser 2.0.7 @ManuDoni are you using the commercial addon with this package?

ManuDoni commented 4 months ago

I'm sorry, but I don't know. I haven't used the commercial add-on.
