ex. \s-1CGI\s0

  use GD::Barcode::QRcode;
  binmode(STDOUT);
  print "Content-Type: image/png\n\n";
  print GD::Barcode::QRcode->new('1234567')->plot->png;

with UnitSize, \s-1ECC\s0 settings

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

GD::Barcode::QRcode is a subclass of GD::Barcode and allows you to create QRcode barcode image with \s-1GD\s0. This module based on \*(L"QRcode image \s-1CGI\s0 version 0.50 (C)2000-2002,Y.Swetake\*(R".

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

Size of modules(barcode unit) (Default = 1).

\fIplot()\fP

$oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]);

creates \s-1GD\s0 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::QRcode->new('1234567'); my $oGD = $oGdB->plot(); # $sGD is a GD image with Height=>20 pixels, with no text.

\fIbarcode()\fP

$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(); $GD::Barcode::QRcode::errStr

has error message. $oGdBar->{$text}

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