Hi,
I've written a very old module which used a lot of pdf primitives like
\pdfescapehex
and \pdfescapename etc. and it turns out not they don't work in mkiv.
So I just want
to know are there any alternatives?
TIA

Best Regards
Chen

I did change your code format("%0X",byte(s)) with format("%s",byte(s)) and it worked as \pdfescapename. I hope I'm not too wrong. Anyway, my ancient module just write directly with pdfobj, I just commented the /ModDate parameters and seems just fine now. I think I really need to learn some lua.
