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

       new

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

       Constructor.  Creates a GD::Barcode::ITF object for $sTxt.  $sTxt has numeric charac-
       ters([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::ITF->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::ITF->new('12345678');
         my $sPtn = $oGdB->barcode();

       $errStr

       $GD::Barcode::ITF::errStr

       has error message.

       $text

       $oGdBar->{$text}
