       string with (0-9, - $ / . + ABCD).

   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.

         my $oGdB = GD::Barcode::NW7->new('123456789012');
         my $sPtn = $oGdB->barcode();
