WebP artifacts not pathological enough?

vote for this feature to be natively supported in browsers

It's already under consideration but needs some work first: https://github.com/mozilla/standards-positions/pull/1064

Strange that Mozilla is going to rely on an internal team at Google to build a decoder for them in Rust, when Google is the one trying to kill JPEGXL.
Mindless2112•1h ago
It's two different teams inside Google. Some part of the Chrome team is trying to quash JPEG XL.
righthand•32m ago
Sure, but if it becomes political I expect the Chrome team to fully quash the JPEG XL team to hurt Firefox and JPEG XL in one go.
breppp•23m ago
It's more likely related to security, image formats are a huge attack surface for browsers and they are hard to remove once added.

JPEG XL was written in C++ in a completely different part of Google without any of the safe vanity wuffs style code, and the Chrome team probably had its share of trouble with half baked compression formats (webp)

It's nice to see Safari lead the pack: https://caniuse.com/jpegxl

And then to actually support the HDR images that can be encoded with JPEG XL, they'd have to implement HDR in the browser graphics pipeline.

Any decade now, any decade...

Can someone comment on what is newsworthy about this?

jpegxl is supported by pretty much every relevant program that deals with images. The web situation is purely because of Google's monopoly.

There has to be someone else since my dad just emailed me a JPEGXL image less than 15 minutes ago. No idea on how he produced or procured it.

The cluster fuck that is DICOM and HL7 once vendors go to town is far from the ‘open’ utopia we dream of.

JPEG XL is alive despite google trying their best to kill it and is used to treat cancer

Nerds like JPEG XL but Google is trying to kill it.

Why does it try to kill it ?
greenavocado•48m ago
Because they can't control it

My first ever job in software was working for PathXL (a Belfast startup implementing digital pathology software). Lots of fond memories working there, including how cool it was working on what was effectively Google Maps but for massive tissue sample images. PathXL actually ended up getting acquired by Philips, seems like a great match if they're building the hardware for this.

They sold them off to Cirdan which is not doing much with the software

Ugh, Pathology image processing is really annoying.

IF Philips is going to stick to the DICOM format, and not add lots of proprietary stuff, _and_ it's the format that it uses internally, then this will be good.

For example, folks can check out OpenSlide (https://openslide.org) and have a look at all the different slide formats that exist. If you dig in to Philips' entry, you'll see that OpenSlide does not support Philips' non-TIFF format (iSyntax), and that the TIFF format is an "export format".

If you have a Philips microscope that uses iSyntax, you are very limited on what non-Philips software you can use. If you want files in TIFF format, you (the lab tech) have to take an action to export a side in TIFF. It can take up a fair amount of lab tech time.

Ideally, the microscope should immediately store the images in an open format, with metadata that workflow software can use to check if a scanning run is complete. I _hope_ that will be able to happen here!

> If you want files in TIFF format, you (the lab tech) have to take an action to export a side in TIFF. It can take up a fair amount of lab tech time.

Worse, you have to do it manually one by one in their interface, it takes like 30 minutes per slide and you only have like 20 minutes after it's done to pick it up and save it somewhere useful otherwise the temporary file gets lost.

DICOM is of course the way to go, but it does have its rough edges - stupid multiple files, sparse shit, concatenated levels and now Philips is the only vendor who makes JPEG XL (next to jpeg, jp2k and jpeg xr).

We learnt to live with iSyntax (and iSyntax2), if you can get access to them that is. In most deployments the whole system is a closed appliance and you have no access to the filesystem to get the damn files out.

zokier•49m ago
In case others are not aware what "pathology scanner" is, apparently it is a device to scan/image microscope slides. Found some specs, apparently these Philips units do 0.25um/px and 15mm x 15mm imaging area, making the output images presumably 60000 x 60000 pixels in size. Apparently Philips previously used their own "iSyntax" format, and also JPEG2000 DICOM files for these devices.
TheChaplain•27m ago
Always impressed when someone does anything with DICOM, it's a bit complex format IMHO.
