Decode or Generate QR Codes in Ubuntu with QtQR and zbar-tools

Sometimes I’ve found myself having to decode a QR code on my computer, and usually I’d just get my Android smartphone, use a QR code app to decode it, and send the results to my computer by email. It works, but wouldn’t it be better to simply do this straight from my computer instead? After a few minutes searching, I eventually found out QtQR graphical utility that can both generate and decode QR codes.

QtQR_Create_QR_Code
In Ubuntu and Debian, you can install it as follows:


You can create a QR code with a given pixel size and level of error correction for text, URL, bookmark, email, phone number, SMS/MMS, WiFi network, and so on, and then use the Save QRCode button to save the resulting picture.
QrQR_Decode_URL If instead you simply want to decode a QR code from an image or your webcam use the Decode button, and the tool will automatically extra the data, and offer you to take action, such as opening an URL address.

If you’d rather use the command line,you could install zbar-tools instead:


The image above was a complete Antutu 6.0 results screenshot, so you don’t need to save/edit the picture with the QR code only, and the app will scan the complete picture. If instead you want to scan a QR code with your webcam use zbarcam.
