DESCRIPTION
       GD::Barcode::EAN8 is a subclass of GD::Barcode and allows you to create EAN8(JAN8) barcode
       image with GD.  This module based on "Generate Barcode Ver 1.02 By Shisei Hanai 97/08/22".

   new
       $oGdBar = GD::Barcode::EAN8->new($sTxt);

       Constructor.  Creates a GD::Barcode::EAN8 object for $sTxt.  $sTxt has 7 or 8 numeric
       characters([0-9]).  If $sTxt has 12 characters, this module calacurates CD for you.

   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::EAN8->new('1234567');
         my $oGD = $oGdB->plot(NoText=>1, Height => 20);
         # $sGD is a GD image with Height=>20 pixels, with no text.

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

       returns a barcode pattern in string with '1', 'G' and '0'.  '1' means black, 'G' also
       means black but little bit long, '0' means white.

        ex.
         my $oGdB = GD::Barcode::EAN8->new('1234567');
         my $sPtn = $oGdB->barcode();
         # $sPtn = '';

   $errStr
