XnView MP uses OpenJPEG, but i think that Phoenix Slides uses internal macos codec


Ok. Phoenix Slides does seem slightly faster than the built-in macos preview app, though.

I've done some more comparisions, and it's not just Jpeg2000 that's remarkably faster, but also decoding large jpeg and ...

I'm on a M1 Pro mac and have to say the performance of viewing jp2 files in XnView is very slow compared to other alternatives. I'd say it's 3-4x slower on large images compared to e.g. Phoenix Slides, which is open source. Some optimisations would be very welcome.

An alias is a shortcut to a folder or file, which is handled by the os.

It seems the classic version had support to adjust the scrolling offset for the cursor keys. This is something I'd very much like to have (the current offset is set way too low in my opinion.)

Any plans on implementing this? It would be really nice.

Scroll value doesn't seem to exist in XnView MP
