NAME
qrencode - Encode input data in a QR Code and save as a PNG or EPS image.
SYNOPSIS
qrencode [-o FILENAME] [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 charac‐
ters, 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)
-r FILENAME, --read-from=FILENAME
read input data from FILENAME.
-s NUMBER, --size=NUMBER
specify the size of dot (pixel). (default=3)
-l {LMQH}, --level={LMQH}
specify error correction level from L (lowest) to H (highest). (default=L)
-v NUMBER, --symversion=NUMBER
specify the minimum 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,PNG32,EPS,SVG,XPM,ANSI,ANSI256,ASCII,ASCIIi,UTF8,UTF8i,ANSIUTF8,ANSIUTF8i,ANSI256UTF8}
--type={PNG,PNG32,EPS,SVG,XPM,ANSI,ANSI256,ASCII,ASCIIi,UTF8,UTF8i,ANSIUTF8,ANSIUTF8i,ANSI256UTF8}
specify the type of the generated image. (default=PNG)
-S, --structured
make structured symbols. Version number must be specified with '-v'.
-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. See MICRO QR CODE for more information.
--rle enable run-length encoding for SVG.
--svg-path
use single path to draw modules for SVG.
--inline
only useful for SVG output, generates an SVG without the XML tag.
