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. 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
              output 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.

EXAMPLES
       qrencode -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.
