SYNOPSIS

       ex. CGI

	 use GD::Barcode::IATA2of5;
	 binmode(STDOUT);
	 print "Content-Type: image/png

";
	 print GD::Barcode::IATA2of5->new('1234567890')->plot->png;

       with Error Check

	 my $oGdBar = GD::Barcode::IATA2of5->new('A12345678');
	 die $GD::Barcode::IATA2of5::errStr unless($oGdBar);   #Invalid Characters
	 $oGdBar->plot->png;

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();

   $errStr
       $GD::Barcode::IATA2of5::errStr

       has error message.

   $text
       $oGdBar->{$text}

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