Barcode Writer in Pure Postscript 2008-01-01 (Default branch)
Image Barcode Writer in Pure Postscript implements the printing of many barcode formats entirely within level 2 PostScript, so that the process of converting the input string into the printed output is performed by the printer itself. This avoids the need to re-implement the barcode generation process whenever your language needs change. The project supports most major barcode formats including EAN-13, EAN-8, UPC-A, UPC-E, ISBN, Code 128 (A, B, and C), Code 39, Interleaved 2 of 5, Postnet, Code 2 of 5, and Codabar.

Initial support for the PDF417 2D symbology was added.Image

	 my $oGdBar = GD::Barcode::QRcode->new('123456789',
				   { Ecc => 'L', Version=>2, ModuleSize => 2}
			       );

DESCRIPTION

       GD::Barcode::QRcode is a subclass of GD::Barcode and allows you to create QRcode barcode image with GD.	This module based on "QRcode image
       CGI version 0.50 (C)2000-2002,Y.Swetake".

   new
       $oGdBar = GD::Barcode::QRcode->new($sTxt,
			   { Ecc => Ecc Mode,
			     Version => Version,
			     ModuleSize => Size of 1 modlue,
			   });

       Constructor. Creates a GD::Barcode::QRcode object for $sTxt.

       Parameters:

       Ecc Ecc mode. Select 'M', 'L', 'H' or 'Q' (Default = 'M').

       Version
	   Version ie. size of barcode image (Default = auto select).

       ModuleSize

   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::QRcode->new('1234567');
	 my $oGD = $oGdB->plot();
	 # $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::QRcode->new('1234567');
	 my $sPtn = $oGdB->barcode();
