Uses 'only 4 bytes', well 8 bits for 4 channels is 4 bytes.. so that's doubling the size per pixel to go to 16 bit per channel. I wouldn't prefix a size doubling with 'only'.

The tl;dr is AVIF and JPEG XL specialize in different types of images and colorspaces. Most controversially AVIF is hardware accelerated while JXL is not. That second part causes JXL nerds to foam at the mouth.

BAD FUCKING IDEA

You're changing the file format, devices everywhere recognize png as containing a certain pattern of bytes, if you change that format you break compatibility with EVERYTHING.

So in the future this means that your PNGs will just randomly not work 50% of the time.

That's why you use new file extensions, representing new file formats...

We NEED a better animated gif format. This isn't up for debate. And a good animated image format absolutely SHOULD be able to handle both lossy and lossless compression methods. The choice should be up to the utilizer which method he wants to use. That webp also does what jpeg and png do further minimizes implementation details and points of error.
You sound like a helpless consumer that thinks websites magically own and mutate images just to inconvenience him.

Completely moot for multiple reasons. AVIF will not hardware decode at resolutions greater than 8192x4096 on any consumer devices. Nobody is buying a fucking hardware image encoder. Never. Period. Nobody's fucking bought one since a physical JPEG card was necessary with a 386. If AVIF wasn't so fucking awful to encode at any reasonable speed without severe quality sacrifices, you wouldn't be mentioning this "need". You can encode JPEG-XL on a fucking Nehalem potato.

APNG would be perfect if it actually let you encode successive frames the way GIF does, like half-assing keyframes by allowing you to draw partial successive frames, or just assign a new frame as "replace". Every frame in an APNG is...a full PNG frame.
WEBP is fucking awful for animated images. If I reach a point where GIF isn't enough (256 colors) AND APNG is too bloated (# of frames exceeds one digit, really high res) I'm not going to use a neutered fuck ass version of VP8 LARP-ing as an image codec...I'm just going to use fucking x264 and save a video.

from what I see they added HDR info using a new png chunk, so older decoders will simply ignore it. god knows how they will decode the info without it though, maybe the same as they do currently? I mean that would be optimal, stuff that doesn't support it will look the exact same as before, but the new things will not have the colors fucked.

to be fair it only says that such a color space is typical with HDR images, not that that's what HDR is. it's just a bit misleading, same deal with this image >>105740453
that said the spec also adds a way to set the color space, so this is relevant here, I guess HDR is just the big buzzword and everyone also associates it with a bigger color space even though that has nothing to do with it

4chan uses cloudflare image compression, the files you download here have been recompressed by cloudflare so they can save 1% on size. As a consequence, if an image is reposted often, it will keep losing quality with every iteration. And Image hash search is now useless as well.

You can get around this by adding a GET tag to the file. for ex. https://i.4cdn.org/g/1750997376061271.jpg will result in 132kb, but https://i.4cdn.org/g/1750997376061271.jpg?fuck=cloudflare will result in the original ~144kb file.

Yup, turns put it's not "da joos!" this time. While video game screenshots make 4:2:0 stand out it's usually not a problem especially if it's viewed on a small display.

HDR images have a larger capacity for color vibrancy AND a larger capacity for higher luminosity. And in my opinion, the expanded luminosity is the biggest draw to HDR. It means that an image of the sun is going to be a little bit brighter than the background of a Microsoft word document.
Anonymous No.105751303 [Report]

All current HDR "display" formats use Rec.2020 as its encoding space, regardless of whether or not the image actually needs that much vibrancy, and regardless of whether or not the technology currently exists to actually display all of Rec.2020 space.
Working space, is a whole different beast entirely. You can have linear floating-point "scene" space be whatever color space you want, even greyscale, as long as you specify it and define its black and white points.
