QR(1)                           Python QR tool                           QR(1)

NAME
       qr - script to create QR codes at the command line

SYNOPSIS
       qr [--help] [--factory=FACTORY] [--optimize=OPTIMIZE]
       [--error-correction=LEVEL] [data]

DESCRIPTION
       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).

OPTIONS
        -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.
