QRENCODE(1)QRENCODE(1)NAMEqrencode - Encode input data in a QR Code and save as a PNG or EPS
image.
SYNOPSISqrencode [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. See SYMBOL VERSIONS for more
information. (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)
-t {PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
--type={PNG,EPS,SVG,ANSI,ANSI256,ASCII,ASCIIi,UTF8,ANSIUTF8}
specify the type of the generated image. (default=PNG)
-S, --structured
make structured symbols. Version must be specified.
-k, --kanji
assume that the input text contains kanji (shift-jis).
-c, --casesensitive
encode lower-case alphabet characters in 8-bit mode. (default)
-i, --ignorecase
ignore case distinctions and use only upper-case characters.
-8, --8bit
encode entire data in 8-bit mode. -k, -c and -i will be ignored.
-M, --micro
encode in a Micro QR Code. (experimental)
--foreground=RRGGBB[AA]
--background=RRGGBB[AA]
specify foreground/background color in hexadecimal notation.
6-digit (RGB) or 8-digit (RGBA) form are supported. Color out‐
put support available only in PNG and SVG.
-V, --version
display the version number and copyrights of the qrencode.
--verbose
display verbose information to stderr.
[STRING]
input data. If it is not specified, data will be taken from
standard input.
SYMBOL VERSIONS
The symbol versions of QR Code range from Version 1 to Version 40.
Each version has a different module configuration or number of modules,
ranging from Version 1 (21 x 21 modules) up to Version 40 (177 x 177
modules). Each higher version number comprises 4 additional modules
per side by default. See http://www.qrcode.com/en/about/version.html
for a detailed version list.
EXAMPLESqrencode-l L -v 1 -o output.png 'Hello, world!'
encode into a symbol version 1, level L.
qrencode-iSv 1 --output=output.png
read standard input and encode it into a structured-appended
symbols in case-insensitive mode.
cat bigfile.txt | qrencode-S -v 40 -l L -o output.png
encode into a symbol version 40, level L.
