DESCRIPTION

       GD::Barcode::IATA2of5 is a subclass of GD::Barcode and allows you to create IATA2of5 barcode image with GD.

   new
       $oGdBar = GD::Barcode::IATA2of5->new($sTxt);

       Constructor.  Creates a GD::Barcode::IATA2of5 object for $sTxt.	$sTxt has numeric characters([0-9]).

   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::IATA2of5->new('12345678');
	 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' and '0'.  '1' means black, '0' means white.

	ex.
	 my $oGdB = GD::Barcode::IATA2of5->new('12345678');
	 my $sPtn = $oGdB->barcode();

   $text
       $oGdBar->{$text}

       has barcode text based on $sTxt specified in new method.
