           $img->write(file => "qrcode.gif");

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

           my $img = plot_qrcode("blah blah", \%params);

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.

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

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

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

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

           •   "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'.

           •   "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)
