Developed by the google research time. Pretty ironic

Sorry non discord users, I don't think they have a matrix bridge atm

So I took a png and used cjxl v0.10.2 and --distance==0 --effort==9 to convert it to a jxl file. And the result has color inaccuracies.

I checked that both files use RGB. In the Black&White part of the images I cannot see any differences, it seems to really be something about colours o this specific image...

Any idea what I could have done wrong?

Incredible improvements for a codec that was already far ahead. In the same way that JPEG has been given new life by mozjpeg and jpegli, I wonder how far the JPEG-XL codec is going to be stretched by better encoders in the near and far future.

Now the JPEG XL Toolbox is released on App Store.

The Pro in app purchase is FREE until Jan 20, 2024.

The Pro version only enables some tweaks for ProRAW decoding.

All the JPEG XL settings are available for FREE version.

Features:

• ProRAW to JPEG XL
• Batch conversion
• Metadata keeping
• Supports 4G RAM devices to convert 48 megapixels ProRAW
• Lossless for JPEG input
• Keeps HDR effect after the ProRAW to JXL conversion

Features in settings:

• ProRAW parameters to adjust the decoding process
• Modular mode
• Progressive mode
• Output colorspace
• Decoding speed option

Happy New Year everyone !

I just released a new version of my android app jxlviewer !

This update bump libjxl version to v0.9.0.

I also hacked a version of Simple Gallery that support jxl files. Try it out !.

My goal is to improve the android library, so that other app can use it safely, and then maybe add official support in Simple Gallery.

@jpegxl Will #jpegXL need additional metadata when used with HTML's srcset?
While the format's progressive rendering can do away with the need to have different files per resolution, browsers will instead need to know how much of the image they'll fetch. How would we pass that information to the browser?
Extra syntax in srcset, eg p.jxl, p.jxl \<2040 100w, p.jxl \<6974 200w to tell that for a 100px wide view the browser needs to load the first 2040 bytes? Fragment identifier tricks?

"A nerd-rock piece of cover music that sings the praise of the new JPEG-XL (aka JXL) image format."

Finally, the missing puzzle piece before world takeover.

Are there any galleries or file managers that support jpeg xl?

So far I only found https://github.com/oupson/jxlviewer

A small list I gathered of software that is yet to support jxl.

A lot of technical discussion happening in the comments here: https://lemmy.world/post/2059816
