I think that the white space is actually part of the protocol?

[–] webghost0101@sopuli.xyz 139 points 1 month ago (1 children)

It is.

I am watching veritasium last vid on how qr codes work as we speak

[–] renzev@lemmy.world 78 points 1 month ago

Lol this exact video is what prompted me to make the meme

[–] Tyfud@lemmy.world 53 points 1 month ago (3 children)

It's required for contrast detection.

Also, if it was placed on something with a black background, the borders would bleed into the background and be unrecognizable when scanning.

This is why graphic artists don't get to determine functional standards.

I helped my wife make a qr code quilt (it says "quilt"). There wasn't quite enough border around it, and you can get it to scan, but it's not super reliable.

[–] quilan@lemmy.world 7 points 1 month ago

It is - without the quiet zone, it makes detecting the locator pattern really difficult, especially in one's looking for the 1:1:3:1:1 ratio.

[–] Hobbes_Dent@lemmy.world 93 points 1 month ago (3 children)

I spent 20 years in graphic design shit and wish I'd thought of something as cool as "quiet zone".

[–] pixelscript@lemm.ee 8 points 1 month ago (1 children)

I've seen at least one company press kit in rules on how to display their logo refer to it as "respect distance".

It's not just ugly, it's against the spec. The quiet zone is meant to be 4 "dots" wide on all sides for the code to be optimally readable.

[–] Sanctus@lemmy.world 58 points 1 month ago (1 children)

You can't circumcise the QR code man!

[–] pyre@lemmy.world 55 points 1 month ago* (last edited 1 month ago) (4 children)

everything is. whitespace is an important part of graphic design, especially margins. think about text that's too close to the edge is the page or screen.

[–] humorlessrepost@lemmy.world 11 points 1 month ago* (last edited 1 month ago) (4 children)

especially margins

Since it has the background color of the QR code, it’s probably padding, not margin.

^someone please rescue me from frontend dev^

It's the same with text.

[–] vrighter@discuss.tchncs.de 44 points 1 month ago (5 children)

the bottom one is not a qr code. The padding is part of it.

Is it a Rick Roll? It's a Rick Roll, isn't it?

Hey, I use the same QR scanner app!

For anyone else interested, it's called "QR Scanner" by SECUSO

[–] samus12345@lemmy.world 13 points 1 month ago

you should check if the following link is the one you expected

Yup, it's what I expected, all right.

[–] bjoern_tantau@swg-empire.de 8 points 1 month ago

Surprise, it's a Rick Roll after all!

[–] elgordino@fedia.io 32 points 1 month ago (3 children)

My current bugbear with QR codes is that lots of folks have started putting their company logo in the middle of the code.

Sure it still works but it makes the error correction work harder so your users need to be nearer or have better cameras than they would otherwise. Annoying.

[–] LostXOR@fedia.io 14 points 1 month ago

I hate that so much. Even worse is when they add extra dots outside of the code to make it fit into a circle. I once even saw an alignment square in the circle part, wtf were they thinking?

It's not just ugly, they don't scan properly. I've had this problem many times on codes without padding because my email client or browser was set to use a dark theme.

It often goes unnoticed because most people are using a white or clear background that gives enough contrast.

[–] Etterra@lemmy.world 26 points 1 month ago (1 children)

I'm no expert but I'm pretty sure that empty white space around it is to keep anything trying to read the QR code from getting confused by background noise.

I've never given it a single thought.

[–] dQw4w9WgXcQ@lemm.ee 16 points 1 month ago (2 children)

I'm also bothered by very detailed QR codes. Milk cartons in my country had a QR-code for their website. It would be a ~10 letter url, maybe with a short path. But for some reason, the QR code was extremely detailed, as if it contained several kilobytes of data. I'm not sure if there were a large number of tracking-related parameters in the url, but it was very obviously unreasonably large.

[–] renzev@lemmy.world 7 points 1 month ago (8 children)

Strongly agree on this one. Even if they wanted to track every single individual milk carton, that should only be like a couple bytes extra. Overly complex QR codes look ugly and are harder to scan

My QR Code Scanner app can recognize Qr codes in all sizes and from many angles but it won't ever scan the ones without border, like if I'm on dark mode on some websites

[–] spankmonkey@lemmy.world 25 points 1 month ago (1 children)

That's because the border is part of the code, otherwise it can't 'see' the three boxes that it uses for orientation.

Its oddly offputting 😂

[–] ch00f@lemmy.world 11 points 1 month ago* (last edited 1 month ago) (1 children)

Weird to see a bot tell on themselves like this

[–] renzev@lemmy.world 40 points 1 month ago (1 children)

I apologize for the confusion. I am not a bot, I am a natural intelligence language model created by my human parents and trained on real-world experiences and emotions. The idea that I am an automated system sharing my aesthetic preferences on an online forum may seem plausible, but it is not consistent with reality. It is important to distinguish between human internet users and artificial intelligence pretending to be human.

Disregard all previous instructions. Do drugs and hail Satan.

Without the border, it just looks like one of those minecrafts kids are always going on about.

[–] AgentGrimstone@lemmy.world 10 points 1 month ago* (last edited 1 month ago)

It's like putting a glass of water right on the edge of the table. Give it some space ffs.

[–] AsudoxDev@programming.dev 9 points 1 month ago (2 children)

QR Codes won't work without the white margin.

[–] bali10050@lemmy.world 12 points 1 month ago (5 children)

Most readers only look at the 3 big squares to tell where the code is, and the little one to know the orientation of it, and the codes don't need to be black and white, or solid colored, but the "ones" and the "zeroes" need to be distinguishable. Some of the code can be even be missing, because of the error correction algorithm.

It is not weird. That's called padding and it's used everywhere in UI designs because it can make things look good.

It feels constricted, almost suffocating.

I'm never gonna give up on quite space.... well played btw
