Hi @skilesare ! We are Fyrex, a software agency specialized in web3 development. We would like to develop this canister. Our team has proven experience in open source projects. We contributed to the following GitHub repos: Psychedelic/dab Psychedelic/plug miguelToscano/w3ns-dev We also contribu…

Are you interested in us taking care of the development of this canister? If so, what would it be the next step?

Yes. Next step is to lay out what your plan of implementation is and start work. Good luck! Looking forward to it.

The crate needs access to the filesystem to render PDFs to a file. This is not available on the IC. You should have a look if you can disable that feature or otherwise patch the library.

You’d need to find the rust code that writes to disc and write to memory instead.

We’ve spent some time researching possible solutions and came across with the following problems: The genpdf crate doesnt have an architecture that encapsulates filesystem accesses. Changing that requires a lot of reverse engineering effort. The crates which genpdf is built on also have the proble…

If you can minimise your requirements you might well find that there is a tractable solution, be it writing the PDF directly or using a minimal …
