QRENCODE(1) General Commands Manual QRENCODE(1)NAME
qrencode - Encode input data in a QR Code and save as a PNG or EPS image.
SYNOPSIS
qrencode [OPTION]... [STRING]
DESCRIPTION
Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a
mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and has high robustness.
Qrencode is a utility software using libqrencode to encode string data in a QR Code and save as a PNG or EPS image.
OPTIONS -h, --help
display help message.
-o FILENAME, --output=FILENAME
write image to FILENAME. If '-' is specified, the result will be output to standard output. If -S is given, structured symbols are
written to FILENAME-01.png, FILENAME-02.png, ... (suffix is removed from FILENAME, if specified)
-s NUMBER, --size=NUMBER
specify the size of dot (pixel). (default=3)
-l {LMQH}, --level={LMQH}
specify error collectin level from L (lowest) to H (highest). (default=L)
-v NUMBER, --symversion=NUMBER
specify the version of the symbol. (default=auto)
-m NUMBER, --margin=NUMBER
specify the width of margin. (default=4)
-d NUMBER, --dpi=NUMBER
specify the DPI of the generated PNG. (default=72)

[STRING]
input data. If it is not specified, data will be taken from standard input.
EXAMPLES
qrencode -l L -v 1 -o output.png 'Hello, world!'
