[−][src]Crate qrcode53bytes
qrcode53bytes
Things are changing fast. 2020-02-17 LucianoBestia ver.1.0.0.
I need to generate a simple QR code for url that has max 53 bytes. I want to do this in wasm.
QR codes are pretty complicated. So specifying only one single use-case makes the code smaller. But it looses universality.
Smaller code is good for wasm.
The url I want to encode is like this:
https://bestia.dev/mem6/#p04.1234
There is a hash symbol here so I cannot use the alphanumeric mode
.
I must use the byte mode
.
There are 33 characters. It means there is some free space for future uses.
The smallest QR code for that is:
- version 3
- 29x29 modules
- ECC Level L
- data bits 440
- 53 bytes
- ISO-8859-1
The code is written by treeman. I just removed all the variants I don't need.
I use this code my wasm project https://github.com/LucianoBestia/mem6_game.
Examples
cargo run --example svg
