       qrencode	 - Encode input	data in	a QR Code and save as a	PNG or EPS im-

       qrencode	[OPTION]...  [STRING]

       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.

       -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).

       -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)

	      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)

	      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, EPS and SVG.

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

	      display verbose information to stderr.

	      input  data.  If	it  is	not specified, data will be taken from
	      standard input.

       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
       for a detailed version list.

       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.

       qrencode	-S -v 40 -l L -r bigfile.txt -o	output.png
	      read input data from bigfile.txt and encode into a  symbol  ver-
	      sion 40, level L.
