barcodes-uc 0.7.0

A library to generate barcodes

Barcodes python module

Thanks to Melisa for her precious help.

⚠️ This python package is still in development. ⚠️

• For now only QR codes are available. Only alphanumeric and byte encodings are available.

Installation

pip install barcodes-uc

You might want to install the package in a virtual environment. For that do:

python3 -m venv venv
source venv/bin/activate
pip install barcodes-uc

Usage

from barcodes_uc.qrcodes import qrgenerator, qrutils

# Generate a QR code
message = "Hello world!"
encoding = qrutils.QREncoding.byte
version, error_correction_level, qr = qrgenerator.get_min_version(message, encoding, qrutils.QRErrorCorrectionLevels.Q)
generator = qrgenerator.QRGenerator(msg=message, encoding=encoding, version=version, error_correction=error_correction_level)
qr = generator.generate()

qr.show() # Show the QR code in the terminal
qr.save("qr.png", imgSize = 1000, colour=[qrgenerator.QRColour.red]) # Save the QR code in a file

CLI tools

The package comes with CLI tools:

QR code generator

qrcode --help

usage: qrcode [-h] [-e {byte,numeric,alphanumeric,kanji}] [-V QR_VERSION] [-E {L,M,Q,H}] [--save SAVE] [--no-show] message

Create QR codes

positional arguments:
  message               Message to encode

optional arguments:
  -h, --help            show this help message and exit
  -e {byte,numeric,alphanumeric,kanji}, --encoding {byte,numeric,alphanumeric,kanji}
                        Encoding of the message
  -V QR_VERSION, --qr-version QR_VERSION
                        QR version, 1-40
  -E {L,M,Q,H}, --qr-error-correction {L,M,Q,H}
                        QR error correction
  --save SAVE           Save the QR code to a file
  --no-show             Do not show the QR code
  
Made by Pedro Juan Royo, @UnstrayCato

The program will show the QR code in the terminal and save it to a file if the --save option is used. If no -e, -V or -E options are used, the program will try to guess the best options for the message.

Future work

• Add byte and numeric encoding to qr codes.

• Save qr code as image in different styles.

• Generate barcodes.
