QRENCODE(1)                                                        QRENCODE(1)



NAME
       qrencode   Encode input data in a QR Code and save as a PNG 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 image.


OPTIONS
        h,   help
              display help message.

        o FILENAME,   output=FILENAME
              write  PNG  image  to  FILENAME. If ' ' is specified, the result
              will be output to standard output.

        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)

        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.

        V,   version
              display the version number and copyrights of the qrencode.

       [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!'
              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.
