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. (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 sup-
	      port 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-insensitive mode.

NAME

       Imager::QRCode - Generate QR Code with Imager using libqrencode

SYNOPSIS

	   use Imager::QRCode;

	   my $qrcode = Imager::QRCode->new(
	       size	     => 2,
	       margin	     => 2,
	       version	     => 1,
	       level	     => 'M',
	       casesensitive => 1,
	       lightcolor    => Imager::Color->new(255, 255, 255),
	       darkcolor     => Imager::Color->new(0, 0, 0),
	   );
	   my $img = $qrcode->plot("blah blah");
	   $img->write(file => "qrcode.gif");

	   # or instance method
	   use Imager::QRCode qw(plot_qrcode);

	   my $img = plot_qrcode("blah blah", \%params);
	   $img->write(file => "qrcode.gif");

DESCRIPTION

       This module allows you to generate QR Code with Imager. This module use libqrencode '2.0.0' and above.

METHODS

       new
	       $qrcode = Imager::QRCode->new(%params);

	   The "new()" constructor method instantiates a new Imager::QRCode object. "new()" accepts the following parameters.

	   o   "size" - Horizontal and vertical size of module(dot). Default is 4.

	   o   "margin" - Margin size of QR Code. Default is 3.

	   o   "level" - Error collectin level. Valid values are 'M', 'L', 'Q' or 'H'. Default is 'L'.

	   o   "version" - Version of the symbol. If specify '0', this module chooses the minimum version for the input data. Default is '0'.

	   o   "mode" - Encoding mode. Valid values are 'numerical', 'alpha-numerical', '8-bit' or 'kanji'. Default is '8-bit'.

	       If not give "casesensitive" then should be given "mode". If 'kanji' is given, characters will be encoded as Shift-JIS characters.
	       If '8-bit' is given, all of non-alpha-numerical characters will be encoded as is. If you want to embed UTF-8 string, choose
	       '8-bit'.

	   o   "casesensitive" - If your application is case-sensitive using 8-bit characters, set to '1'. Default is '0'.

       plot($text)
	       $img = $qrcode->plot("blah blah");

	   Create a new QR Code image. This method returns Imager object ploted QR Code with the given text.

INSTANT METHODS

       plot_qrcode($text, \%params)
	   Instant method. $text is input text. %params is same parameter as "new()".
