Hello,
what option should I use to produce lossless JPEG-2000 files, is it "-comp_ratio 100"?
And what are the differences between the two JPEG-2000 plugins:
JPEG 2000 LWF JPEG-2000 JP2/JPC File format (read/write) (Can only save images up to 4096x4096 pixels)
JPEG 2000 JPEG-2000 JP2 File format (read/write)
Which one is used if I have both installed?
comp_ratio for lossless JPEG-2000 .jp2?

They use different codec engine, the lwf one in a commercial product. If you have the 2 plugins, luratech is used...And what are the differences between the two JPEG-2000 plugins:
