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.

	       is 4.

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

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

	   o   "version" - Version of the symbol. If specify '0', this module

	       '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");
