Would you be able to circle these highlights? I viewed

at 100% magnification at peeped around for a few minutes but didn't notice anything. Maybe my eyes / monitor is bad...

Oh crap, it's this image

I was talking about. He linked another one! Guess people finally realized that one sucks and now they have a new one. I screwed up.
They didn't even have the halo back then!
replyI'm looking as closely as I'm able, and I don't see what you mean. (I'm not a car guy, or a photo guy.) What do you mean by highlights? What am I looking for? Reflections?
replyLook between the Eni and ApeCoin logos. In lossless you can see there are lines from what I assume separate pieces assembled together. Next to ApeCoin there's also a round piece in the lossless version which is missing from the AVIF. JPEG XL loses most of these as well though.
replyThat's what I noticed anyway, not a car or photo guy either.
The original is a single photo.
replyIf you are referring to "lines from what I assume separate pieces assembled together." I didn't mean that the photo was assembled from multiple pieces, I meant that part of car was (panels or similar). Those lines between panels were no longer visible.
replyOh, yeah, haha!
replyI agree fwiw. The only one that looks bad to me is jixel at lower qualities.
replyOH WAIT. I KNOW WHAT'S HAPPENING HERE.
replyYou're looking at it in a browser that doesn't support JPEG XL, so it's falling back to a WASM renderer, and I think it handles resizing differently.
This is totally my bad. I thought I was doing a good thing by adding that fallback renderer, but it isn't identical and it's giving people the wrong impression.
The lossless version is JPEG XL, hence the difference to AVIF.
I also feel like sometimes the lossless image 'sticks' even after having released the button. Don't know how to reliably test that, though.
replyIn Firefox 157.0.1, the right border of the image moves by a pixel or two when I press "hold for lossless" while viewing the AVIF. I think it's the lossy AVIF that's a bit too small.
replyThat's what I'm talking about. JXL support landed in 158.
replyBut why does missing JXL support make the AVIF too small? It ends one pixel before the gray background.
replyby the way, why not convert everything to png for comparisons to avoid browser support issues?
replyAll browsers support AVIF and JPEG XL now. I was hoping to keep their download size benefits.
replyFirefox added support only 3 days ago! And this doesn't cover the ESR version.
replySure but this is a technical post aimed at a technical audience.
