qr − script to create QR codes at the command line
qr [−−help] [−−factory=FACTORY] [−−optimize=OPTIMIZE] [−−error−correction=LEVEL] [data]
This script uses the python qrcode module. It can take data from stdin or from the commandline and generate a QR code. Normally it will output the QR code as ascii art to the terminal. If the output is piped to a file, it will output the image (default type of PNG).
−h, −−help
Show a help message.
−−factory=FACTORY
Full python path to the image factory class to create the image with. You can use the following shortcuts to the built-in image factory classes: pil (default), png ( default if pillow is not installed), svg, svg-fragment, svg-path.
−−optimize=OPTIMIZE
Optimize the data by looking for chunks of at least this many characters that could use a more efficient encoding method. Use 0 to turn off chunk optimization.
−−error−correction=LEVEL
The error correction level to use. Choices are L (7%), M (15%, default), Q (25%), and H (30%).
data
The data from which the QR code will be generated.
