Ew, and some years ago I almost but not quite entirely rewrote pnglite exactly because med data has to be lossless, mostly grayscale, in tens of megabytes, and JPEG2000 doesn't even approach to cut it. Something like 10-20Mpix lossless grayscale, well, actually approaching good old xray photos.

What possesed someone to actually attempt to use JPEG2000 I do not understand.
