PDF generation from XML requires FreeSans.ttf #387

Closed Heavenfighter closed 1 month ago

Heavenfighter commented 1 month ago

The action pdf of the CLI which transforms XML to PDF throws an error, that the FreeSans.ttf is missing. It is not sufficient to install that font, it must explicitly be present in the calling directory.

Tested on Windows 10 system.

The reason that this did not work properly was the reason why xml2pdf could not be finished before the new priority had to become UBL, due to new legislation. And that was also the reason why this functionality way never announced.

I will remove this functionality unless someone manages to embed the font (and all other neccessary artefacts) in the jar file. The output has to be valid PDF/A-1, though, just PDF is not sufficient.

email me if you want to contribute that functionality, maybe we could have a 30min workshop or so, otherwise: Apologies for the inconvenience, this functionality needs a reboot. And will be removed until it got it.

To keep this feature would be nice, since its a great alternative for visualization of xRechnung documents beside the HTML variant. I'm not sure if i can contribute something because i have no experience in FOP, but i will take a look.
