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%).
