[ome-users] [Bio-Formats] JPEG-XR via CZI

[Alexandre Dufour]

Thanks for the prompt reply Josh.

Just for my information: since it appears this isn’t going to be done anytime soon, and we do have a lot of users no this new machine, what alternative solution should I lean towards (in other words, what should I tell them)?

Cheers
Alexandre
