         binmode(STDOUT);
         print "Content-Type: image/png\n\n";
         print GD::Barcode::QRcode->new('1234567')->plot->png;

       with UnitSize, ECC settings

         my $oGdBar = GD::Barcode::QRcode->new('123456789',
                                   { Ecc => 'L', Version=>2, ModuleSize => 2}
                               );

DESCRIPTION
       GD::Barcode::QRcode is a subclass of GD::Barcode and allows you to

       image CGI version 0.50 (C)2000-2002,Y.Swetake".

   new
       $oGdBar = GD::Barcode::QRcode->new($sTxt,
                           { Ecc => Ecc Mode,
                             Version => Version,
                             ModuleSize => Size of 1 modlue,
                           });

       Constructor. Creates a GD::Barcode::QRcode object for $sTxt.

       Parameters:

       Version
           Version ie. size of barcode image (Default = auto select).

       ModuleSize
           Size of modules(barcode unit)  (Default = 1).

   plot()
       $oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]);

       creates GD object with barcode image for the $sTxt specified at new
       method.  $iHeight is height of the image. If NoText is 1, the image has
       no text image of $sTxt.

        ex.
         my $oGdB = GD::Barcode::QRcode->new('1234567');
         my $oGD = $oGdB->plot();
         # $sGD is a GD image with Height=>20 pixels, with no text.

   barcode()
       $sPtn = $oGdBar->barcode();

       returns a barcode pattern in string with '1' and '0'.  '1' means black,
       '0' means white.

        ex.
         my $oGdB = GD::Barcode::QRcode->new('1234567');
         my $sPtn = $oGdB->barcode();

   $errStr
