So at the moment, we are trying to achieve an integration with the Danish service NETS. That allows danish citizens to sign documents using our national identification service NemID.
Basically, we just want to convert a .docx -> .pdf, and then send that to the official NETS Signing Service.
Our problem though, is that Nets has a very strict whitelist of tags that the PDF's are allowed to include.
We have gotten our documents to follow all these guidelines. Except the tags /F1, /F2 etc.
So far, we have identified, that the /F* tags seem to be connected to embedded fonts in the document.
The NETS service claims to support embedded fonts. So I am unsure wether PHPDOCX's font embed, uses a different approach to embed the fonts, or we have missed something entirely, that would make those /F* tags go away.
Do you know any way to either avoid embedding fonts and the /F* tags alltogether in the PDF? - or a way to embed them with a different approach, that would not include those tags?
