ZUGFeRD: Which PDF lib to use to produce PDF/A-3

[Pascal]

Hello,

i am going to start to build a package to build and read ZUGFeRD-eInvoices.
The question is: Which lib should i use to build PDF/A-3, which is needed to embed the XML with structured data?

Pascal

If you required not having any GUI dependencies (eg: running on a headless server), then your options are seriously limited. FPC (trunk)'s fcl-pdf (which also works with FPC 2.6.4 and FPC 3.0.0) is the only Object Pascal based PDF library I know of that doesn't have any GUI dependencies. Unfortunately I haven't gotten around to implement any PDF/A support yet. Patches are always welcome though.

Hmm...yes it should be without GUI dependencies, but i think i will not be able to implement PDF/A-3 output.

Since there doesn’t seem to be any active library development for pdf in free pascal, wouldn’t it be possible to integrate python libraries into Lazarus? Python has a much bigger development community.

FCL-PDF is actively developed, don't know if it supports PDF/A however.

And everyone can integrate Python libraries using Python4Delphi/Python4Lazarus though it would be better to try to find some native library that is usable for this.

Would an API wrapper for GhostSript be helpful?

If so see https://forum.lazarus.freepascal.org/index.php/topic,61130.0.html

Hi
It might be worth checking, if someone has created bindings for the newest "muPDF" library, it works pretty well...
