So to conclude would anybody know how I can decode QR-codes from images in (preferable pure) Python? All tips are welcome! Since I don't like this service to be dependent on other API endpoints I would want to keep the decoding local though. PyXing ( website here) is supposedly a Python port of the popular Java ZXing library, but the initial and only commit is 6 years old and the project has no readme or documentation whatsoever.įor the rest I found a couple qr- encoders (not decoders) and some API endpoints which can decode for you.
So I decided to find yet another library. It furthermore needs ZBar and is thus not pure Python.
#Qr code reader from image install
Although I want to run my code on Heroku (and thus prefer a pure Python solution) I successfully installed it on a Linux box (with sudo apt-get install python-qrtools) and tried running it: from qrtools import QRĬ = QR(filename='/home/kramer65/qrcode.jpg')Ĭ.data_to_string() # prints '\xef\xbb\xbfNULL' where I expect an int (being `1234567890`)Īlthough this seems to decode it, It doesn't seem to do it correctly. I suppose it refers to this repo which says it is based on ZBar (see above). I also tried it with python-qrtools, qr-tools, python-qrtools and a couple more combinations, but unfortunately to no avail. So I tried installing it using sudo pip install qrtools, which can't find anything. M圜ode = QR(filename=u"/home/psutton/Documents/Python/qrcodes/qrcode.png") QRTools, which according to this blogpost can decode images easily by using the following code: from qrtools import QR
I tried to suggestions in the answers to this SO question, but I can't seem to solve it. This fails with error: command 'cc' failed with exit status 1.
#Qr code reader from image mac osx
ZBar ( website here) claims to be "an open source software suite for reading bar codes from various sources, such as image files." So I tried installing it on Mac OSX running sudo pip install zbar. Furthermore, the website refers to Ubuntu 8.10 (which came out more than 6 years ago) and I can't find a public (git or other) repository of it to check the latest commit. So I tried the code above with both pyqrcode and qrcode, but both fail at the second line saying AttributeError: 'module' object has no attribute 'Decoder'. The thing I find strange about the example code above however, is that it only imports qrcode (and not pyqrcode though) Since I think qrcode refers to this library which can only generate qr-code images it kind of confused me. So I simply installed it using sudo pip install pyqrcode. PyQRCode ( website here) which supposedly can decode qr codes from images by simply providing a path like this: import sys, qrcode I've found a couple libraries which claim to do this: I've got a jpg file with a QR-code which I want to decode using Python. TL DR: I need a way to decode a QR-code from an image file using (preferable pure) Python.
