PDF 1.7 merge not working

[applyACS]

When merging with PDF 1.7 version it is not working
"'Array to string conversion' in 'raw-content'" - I get this when using TcpdiDriver
and of course:
"'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)' in 'raw-content'" - this for FPDI

Yes some pdf features seems to make tcpdi blow up. I need the pdfs you are trying to merge to be able to reproduce. What php and lib versions are you using?

This is the pdf 1.7. The other one is generated using wkhtmltopdf(no issue here).
php 7.3 or 7.4
iio/libmergepdf: 4.0.3

I encounter the same issues as above. Do you have any results @hanneskod ?

[kaystrobach]

@lgme can you please also provide the file - this makes it easier to debug and maybe raise a bugreport at Tcpdi and other used projects.

[lgme]

@kaystrobach Sure. Here:

It seems that for PDF 1.7 you need a commercial FPDI PDF-Parser. See more details here and here.
