that would be nice, because i create them by converting a png from a pipeline output to jxl:
take picture with camera of a printed out image -> cut it with a pipeline to size (like those pdf scanner apps for phones) -> now convert .png to .jxl to save a lot of memory (affinity photos). ( like 360 images at 12mp [3gb] -> [700mb] or so in jxl format)
