JPEG 2000 (dead)

Not sure what you mean by "dead", but tons of book scans, particularly those at archive.org, are PDFs of entirely JPEG2000 images.

Believe it or not, but digital cinema projection is done with jpeg 2000 https://en.wikipedia.org/wiki/Digital_cinema

That’s wild!

I mean dead as in the fact that it’s used somewhere is noteworthy.

I’d love for JPEG XL to replace such uses!
