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 out‐
put 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), pymaging, 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%,
default), Q (25%), and H (30%).
