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, FILE-
	      NAME-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)

       -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.

       [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-insen-
