NAME
qr - script to create QR codes at the command line
SYNOPSIS
qr [--help] [--factory=FACTORY] [--optimize=OPTIMIZE] [--error-correc-
tion=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 fac-
tory classes: pil (default), png ( default if pillow is not in-
stalled), svg, svg-fragment, svg-path.
--optimize=OPTIMIZE
Optimize the data by looking for chunks of at least this many char-
acters 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%, de-
fault), Q (25%), and H (30%).
data
The data from which the QR code will be generated.
