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.
