DESCRIPTION
       GD::Barcode::EAN13 is a subclass	of GD::Barcode and allows you to
       create EAN13(JAN13) barcode image with GD.  This	module based on
       "Generate Barcode Ver 1.02 By Shisei Hanai 97/08/22".

   new
       $oGdBar = GD::Barcode::EAN13->new($sTxt);

       Constructor.  Creates a GD::Barcode::EAN13 object for $sTxt.  $sTxt has
       12 or 13	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::EAN13->new('123456789012');
	 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::EAN13->new('123456789012');
	 my $sPtn = $oGdB->barcode();
	 # $sPtn = '';
