That example is looking at a specific file size. So what he's saying is that he was unable to produce a JPEG 2000 image in a file that size from that image, not from an image of that resolution in general.



He didn't try hard enough. OpenJPEG has a file size parameter, which can go well below its -q 0 size. I was easily able to generate a 16.9K jp2 by specifying the size: https://dl.dropboxusercontent.com/u/54412753/doom9/fish.jp2 which in png looks like: https://dl.dropboxusercontent.com/u/54412753/doom9/fish.jp2....

Looks better than anything else but BPG at that size, to me, although FLIF obviously isn't optimized for lossy.


Thanks for pointing this out! I only tried ImageMagick convert at minimum -quality. Sorry about that.
