XnView Software

Are there plans (or is it there already silently?) to implement a lossless crop for JXL? presumably reencoding any sliced areas losslessly (or near enough).

I guess it's a better idea to ask the developers of JPEG XL.

Most likely not

Many thanks. I suppose the question could be taken more broadly as to whether anyone in the IT world is looking at such a thing, such that xnview could use it (passing the file and selection rectangle values) without having to do the fine coding.
