Which parameters is XNView MP using for JPEG Lossless compression...? I am using compression level 7 (I think it was default..?)
I have been lately using also Image Magick (magick) for compressing jxl but for whatever reason I get larger files with imagemagick
magick input.jpg -auto-orient -quality 100 output.jxl
magick input.jpg -auto-orient -quality 100 -define jxl:effort=9 output.jxl
e.g. last experiment, simple timetable.png, size 160kB, XN MP makes it 116kB, with magick it becomes 145kB and even when putting max effort 9 it is still 136kB, larger than XN MP
I just updated magick to latest version, I think it has libjxl 0.12 or something. So most likely it should be even newer than one on XN MP...?
JPEG XL lossless compression parameters...?
