Python bindings for zxing-cpp

The package uses scikit-build-core as its build backend and nanobind for the Python bindings.

Installation

pip install zxing-cpp

To build from a checked out / extracted soruce tree, a suitable build environment including a C++20 compiler is required:

pip install .

Usage

Reading barcodes

import cv2, zxingcpp

img = cv2.imread('test.png')
barcodes = zxingcpp.read_barcodes(img)
for barcode in barcodes:
	print('Found barcode:'
		f'\n Text:    "{barcode.text}"'
		f'\n Format:   {barcode.format}'
		f'\n Content:  {barcode.content_type}'
		f'\n Position: {barcode.position}')
if len(barcodes) == 0:
	print("Could not find any barcode.")

Writing barcodes

import zxingcpp
from PIL import Image

barcode = zxingcpp.create_barcode('This is a test', zxingcpp.BarcodeFormat.QRCode, ec_level = "50%")

img = barcode.to_image(scale = 5)
Image.fromarray(img).save("test.png")

svg = barcode.to_svg(add_quiet_zones = False)
with open("test.svg", "w") as svg_file:
	svg_file.write(svg)
