What I’ve also done is created a programmatic way to render SVGs to PDF (in a local copy). And most importantly, that same script will find all occurrences of PPAU_AUTH_TAG and PPAU_PRINT_TAG in the SVGs and replace those lines with the contents of ppau_auth_tag.txt and ppau_print_tag.txt respectively.
I’ll be improving on the build system in the next little while (more render formats!), and retrofitting my SVGs to have the new placeholder tags.
Update: we’ve done the sensible thing and forked it over to the PPAU repo. Future things will happen there:
If you have SVG format artwork sitting on your disks, get in touch with Tom or I so it can be added. Not sure how we’ll do Illustrator files yet though.
I’m considering switching renderers, specifically from rsvg-convert to Inkscape (it’s heavier, but better quality). If this would be a breaking change for anyone, speak now.
Ping @rundll (I don’t know of anyone else who might have tried to use this yet).
