Can someone comment on what is newsworthy about this?
Nerds like JPEG XL but Google is trying to kill it.
Philips announces digital pathology scanner with native DICOM JPEG XL output

Re: Philips announces digital pathology scanner with native DICOM JPEG XL output
#12My 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.

#13Earlier quoted context omitted.
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.
It's two different teams inside Google. Some part of the Chrome team is trying to quash JPEG XL.

#14Ugh, 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!

#15https://connect.mozilla.org/t5/ideas/support-jpeg-xl/idi-p/1... vote for this feature to be natively supported in browsers
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...

#17In 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.
