P: JPEG XL support

Photoshop doesnt seem to be able to save CMYK files as jpeg XL and there is no support for jpeg XL in indesign (RGB or CMYK)

Probably 3 years to late, but better late then never 🥲

And when converting to 16bit from 32bit, the image goes 100% black

Legend, thank you Stephen. This support really matters. Now only if we can also do Lightroom next for workflow 😄

TIFF is showing it's age bigtime. The quicker we can elimiate the better with jpegxl's superior compresssion 

One problem I see straight off the bat with Photoshop Beta, it opens 16bit jpegxl as 32bit and washes out the entire image. TIFF doesnt with this. 

@Stephen Nielson Very excited about the Jpeg XL support so far.

I downloaded a bunch of test jxl files such as from here: https://github.com/libjxl/conformance/tree/master/testcases

There seem to be a few that do not open such as "spot", "cmyk_layers", and "alpha_premultiplied". I am not familiar enough with Jpeg-XL to know how common the problematic features are in the non-working ones to warrant fixing, but figured you might want to look into them. 

But besides those it seems that it has wide support for the cool advanced features of Jpeg XL like the procedural generation, which is great.

Edit 2: I deleted a bunch of stuff where I was talking about how the "_5" / "Level 5" test images weren't loading but turns out it was because they were symbolic links and were downloaded as text files, oops.

Employers of the year! lol, 2 years to add to BETA haha

JPEG XL support is now available in Photoshop Beta. Make sure you have updated to the latest version of Beta, and then you can find it in File > Save a Copy under the Formats menu.

This feature is still in Beta because we want to hear more feedback from you on what you like and don't like. Please respond here with any feedback!

We're going to go another year as paying Photoshop customers and not get JPEG XL support, aren't we?  Ridiculous.

I don't understand why it's taken 3 years to implement JXL support. macOS, Affinity Suite, even open source apps all now support JXL. But I guess we're too much into AI and Neural filters to worry about such trivial things as a superior image format as JXL
