PNG is back!

[sentient_loom@sh.itjust.works]

I've never heard of webP. Looked it up. Not impressed. Sticking with png.

Again, that would be TIFF. TIFF images can be encoded either with each line compressed separately or with rectangular tiles compressed separately, and separately compressed blocks can be read and decompressed in parallel. I have some >100GiB TIFFs containing elevation maps for entire countries, and my very old laptop can happily zoom and pan around in them with virtually no delay.

HDR PNG is huge

The main advantage of webp is that it has good lossy compression, which makes it great for websites that show tens or hundreds of images on a single page

[fizzyorange@programming.dev]

WebP was the first widely supported format to support lossy transparency. It's worth it for that alone.

[aeroplayne@lemm.ee]

Do you remember png? Well now it's back. In pog form!

[bob_lemon@feddit.org]

That's because Google removed the support from chrome after only a few months, and Mozilla never added it to Firefox.
And although there's apparently an extension for both, (lossy) image formats need out of the box browser support to have any chance for any kind adoption.

[mindbleach@sh.itjust.works]

Yeah, adoption's not a feature you can design.

The general idea may show up in any extensible format. Like a PNG encoder that only does Sub filter can encounter each pixel once.

... wait, PNG filtering is byte-level? It doesn't change with bit depth? Christ.

[laggykar@programming.dev]

Lossless WebP is still gets way better compression than PNG though, this doesn't change that. Although they mention they're looking to improve it in the next version, so we'll see then.

[betterdev@programming.dev]

Um, actually it's pronounced png

[rizzrustbolt@lemmy.world]

Eventually they'll adopt the multi-page specs and finally push Adobe off the mountain.

[soc@programming.dev]

Happily using it for presentation slides.

Correct. Like "plunge" without the "lu".

[almacca@aussie.zone]

Took me a second to realise you're not talking about Papua New Guinea.

[grant_m@lemmy.ca]

Yes. But does Lemmy support .png?

Ahh.
