Hi all,
I am on a modernization for our pdf importer.
I would like to replace poppler becouse its gpl v2 and the license is just
difficult to digest for our code.
We have 2 other options where to move to.
1) Apache PDFBox, with the price of needing java. But our own project. maybe
we could have a collab there.
I worked with PDFBox years ago. It is in general a lower level object level
(COS) layer api. My team built a PDF to Powerpoint converter. It still runs,
but I don’t have access to the code base. The lesson though is it is
significant work to take PDF a print file format back into the component parts.
We did the work over many years on the side.
the conversion from PDF into components we have the code already and we
can reuse it.
2) PDFium, with the price of beeing class b BSD license, but native
implementation.
Being C++ this is likely a better fit.
Can we simply use it? or is there some review process necessary?
I try our own food first. Then we still can decide to move on.

A second thing.
Import yes or no, we maintain an own pdfparser. It reads pdf, identifies
passwords encrypts and so on.
It is not the full import, just enough to identify and open the file in a
special case of hybrid pdf.
We could replace that code with qpdf. It would serve the same purpose, same
license. But less maintenace for us.
From https://gpdf.dev
gpdf is an open-source, MIT-licensed PDF generation library for Go
That’s not a parser.
I am proposing QPDF https://github.com/qpdf/qpdf
Is that something we should go for?
Best of luck,
Dave
All the best
Peter
