I mean… if we reeeaaally wanna carbon date ourselves…
The whole man is insufficient Data, I love Data so much 🥹
That smirk is what makes it
All that’s missing is the modem ear rape.
Unironically I love that so much lol
On the off chance you haven’t experienced the Floppotron:
I fuckin love the floppotron! 🥰
Glory to the Floppotron!
Didn’t GIFs load from the bottom?
No. You’re thinking of jifs
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.
I distinctively remember GIFs loading bottom to top, left to right, which does not make sense with a rotation flag. Not sure why you’re pulling PNG into this, that’s an entirely different file format.

Just mentioning what format I remembered it with since I dont remember if the rotation flag was in the image file formatting, in the webpage, or if it could be specified in either place.

Fyi, dithering hinders most modern compression algorythms, making the pic bigger.
We listened to music as 41kB RealAudio files that sounded like the song was underwater, which was the style at the time.
This JPEG is just 41 KiB, which was the style shortly after I was born.
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.
how small can u get this with the text still readable?

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.

Dithering is so fucking cool. At some point I wanna check out that game that uses a ton of really stylized dithering - return of the obra djin I think?
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.
JPEG also reduces color depth as it’s first step but just in a smarter way. RGB is converted into YCbCr.
You’ve phrased this like a disagreement, but I don’t see how.
Although maybe I’m just so jaded, that people providing interesting tangentially related trivia are perceived as being hostile unless they announce that as their intent, because usually unannounced trivia is leveled as an attack.
It’s just extra information. Not an attack or disagreement.
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.
I mean, that’s what dithering is
An artifact that your brain processes as something else.
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.
Compressed textures on modern GPUs actually use similar compression: a color palette followed by indexes into the palette. But that’s done per 4x4 pixel block.
What do you mean “at the time”?
What time are you talking about?At the time when dithering was commonly used to achieve the illusion of more available colors, i.e. the 80s and the first half of the 90s.
I’m not really convinced that file compression was “mature” at the time. Text compression was reasonable progressed but image compression was created for a reason besides just a requirement for fixed compression ratio.
But I do agree that dithering was limited in it’s usefulness.
My point was just that dithering existed in print media, so it was one of the first ways they used to reduce image size, they just copied over the same technique
I’m thinking of file compression formats like Zip, LHA and ARJ, which would work particularly well if the image was not dithered and used run-length encoding (e.g. the PIC format of the Atari ST). The PNG format still uses the deflate algorithm which is essentially identical to the compression used by PKZip in 1991.

I miss dithering. It’s got a certain je ne sais quoi.
Mmh, diffuse dither … give me some Bayer dither!
