Hi everyone! I'm writing about the metadata of pdf. The point is that I would like to set them for the file generated by lualatex. So, the question: how to do this?
I know that it can be done via \pdfinfo from pdftex, but I would like to know if it is possible to achieve the same result via lua(la)tex. I am aware of the existence of the library pdf, but I didn't really get how to use it. Moreover, I would like to know if it is even possible to set other fields, for instance those ones that the combo hyperxmp+hyperref lets you set. Finally: does there exist a way to set a password to protect the pdf using luatex? Thanks! All the best, andrea
