       GD::Barcode::Code39 is a subclass of GD::Barcode and allows you to create CODE-39 barcode image with GD.  This module based on "Generate

	 # $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.
