ZbarLight

zbarlight is a simple wrapper for the zbar library. For now, it only allows to read QR codes but contributions, suggestions and pull requests are welcome.

zbarlight is compatible with Python 2 and Python 3.

zbarlight is hosted on Github at <https://github.com/Polyconseil/zbarlight/>.

Installation

You need to install ZBar Bar Code Reader <http://zbar.sourceforge.net/> and its headers to use zbarlight:

• on Debian, apt-get install libzbar0 libzbar-dev

• on Mac OS X, brew install zbar

Then you should use pip or setuptools to install the zbarlight wrapper.

How To use ZbarLight

The new way:

from PIL import Image
import zbarlight

file_path = './tests/fixtures/two_qr_codes.png'
with open(file_path, 'rb') as image_file:
    image = Image.open(image_file)
    image.load()

codes = zbarlight.scan_codes('qrcode', image)
print('QR codes: %s' % codes)

The deprecated way:

from PIL import Image
import zbarlight

file_path = './tests/fixtures/one_qr_code.png'
with open(file_path, 'rb') as image_file:
    image = Image.open(image_file)
    image.load()
converted_image = image.convert('L')  # Convert image to gray scale (8 bits per pixel).
image.close()

raw = converted_image.tobytes()  # Get image data.
width, height = converted_image.size  # Get image size.
code = zbarlight.qr_code_scanner(raw, width, height)

print('QR code: %s' % code.decode())
