pngcrush gets it down to 21.1 kB with no loss of quality.
I tried posting the file, but Lemmy converts it to the atrocious webp format automatically.
this post is just 42kib

JXL for the win! when will we get support for it in firefox though…

Fyi, dithering hinders most modern compression algorythms, making the pic bigger.

Excuse me, I forgot the text. Wouldn’t be fair without all that entropy. To make up for it, I turned on chroma subsampling. This one is 39 KiB.
Kolanaki@pawb.social 2 days ago
To be more accurate, the dithering was more specific to animated gifs and not static pictures.

how small can u get this with the text still readable?

43KiB, though obviously a chunk of that is from the colors of the jpg Professor.

Dithering is much older than jpeg.
They used dithering in printed media, so it was transfered to digital media as a way to save on color depth, before jpeg got invented.

We listened to music as 41kB RealAudio files that sounded like the song was underwater, which was the style at the time.

Dithering is so fucking cool. At some point I wanna check out that game that uses a ton of really sylized dithering - return of the obra djin I think?

Obra Dinn’s filter hurt my eyes. A lot of these filters do and glad many are toggles in the options.

That’s very fair, that’s a consequence of using a shader based artstyle I really hadn’t considered

Dithering is still to this day extremely useful for making custom wall art in Minecraft using maps, because maps have a very specific and limited pallette.

Back when image compression was just reducing the resolution and color depth.
CookieOfFortune@lemmy.world 7 hours ago
JPEG also reduces color depth as it’s first step but just in a smarter way. RGB is converted into YCbCr.
einfach_orangensaft@sh.itjust.works 1 day ago
i mean yeah, its a honest loss of information, jpg on the other hand introduces compression artifacts that are basically hallucinations, meaning it pretends to have more data than it actually has and humans compensate for that thru image recognition and fantasy.
PeriodicallyPedantic@lemmy.ca 1 day ago
I mean, that’s what dithering is
An artifact that your brain processes as something else.
tias@discuss.tchncs.de 1 day ago
It’s really only helpful for formats that will be directly read by hardware (the video chip) and where the “compression” ratio (I would prefer the term quantization) needs to be fixed. For file compression, which was quite mature but CPU- and memory-intensive at the time, the dithering only makes it more difficult to compress further.
PeriodicallyPedantic@lemmy.ca 1 day ago
What do you mean “at the time”?
What time are you talking about?

And websites would have a link to a page and say “Warning! This page contains a lot of pictures!” so you wouldn’t click it unless you were prepared to put your other browsing on hold for a little while

Didn’t GIFs load from the bottom?
Jimmycakes@lemmy.world 1 day ago
No. You’re thinking of jifs
Verat@sh.itjust.works 1 day ago
It was top to bottom unless the image had a rotation flag in it. I don’t remember if it was just PNG that had that or if other formats could too.
