Generate QR Code

Category: Image

Status: Registered and callable in the CyberChef 11.3.0 compatibility inventory.

Input / output: string → ArrayBuffer

Background: https://wikipedia.org/wiki/QR_code

What it does

Generates a Quick Response (QR) code from the input text. A QR code is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached.

Note

Status here means the operation name is implemented and callable. It does not by itself promise byte-for-byte parity for every upstream option. See Compatibility and current status for the verified scope and known boundaries.

Arguments and options

Arguments are positional. Keep their order when using bake() or Pipeline.then().

Index	Name	UI type	PyChef default	Accepted values / format
`0`	Image Format	`option`	`'PNG'`	`'PNG'`, `'SVG'`, `'EPS'`, `'PDF'`
`1`	Module size (px)	`number`	`5`	A Python integer or floating-point value
`2`	Margin (num modules)	`number`	`4`	A Python integer or floating-point value
`3`	Error correction	`option`	`'Low'`	`'Low'`, `'Medium'`, `'Quartile'`, `'High'`

Recipe template

Important

This is a call template built from the documented defaults. Replace placeholder values such as empty keys, paths, patterns, or lookup data before running it.

from pychef import bake

input_value = "example"
args = ['PNG', 5, 4, 'Low']
result = bake(input_value, [{"op": 'Generate QR Code', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['PNG', 5, 4, 'Low']
transform = Pipeline().then('Generate QR Code', *args)
result = transform("example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.generate_qr_code. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.generate_qr_code import run

result = run("example", tuple(['PNG', 5, 4, 'Low']))

pychef.operations.by_operation.generate_qr_code.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

value (str | bytes)
args (Sequence[Any])

Return type:

str | bytes
