zxing-cpp 2.3.0

Python bindings for the zxing-cpp barcode library

Python bindings for zxing-cpp

Installation

pip install zxing-cpp

or

python setup.py install

Note: To enable position independent and multi-symbol DataMatrix detection, the library needs to be compiled with a c++20 compiler. Unfortunately some build environments (currently the 32-bit builds for Linux) used by cibuildwheel to generate the binary wheels that are published on pypi.org don't include a c++20 compiler. Best chance to enable proper DataMatrix support in that case is by installing from source:

pip install zxing-cpp --no-binary zxing-cpp

In that case or if there is no pre-build wheel available for your platform or python version or if you use setup.py directly, a suitable build environment including a c++ compiler is required.

Usage

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.")
