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

  new

    Constructor. Creates a GD::Barcode::ITF 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*.

      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.
