gd::barcode::upce

Barcode::UPCE(3)					User Contributed Perl Documentation					  Barcode::UPCE(3)

NAME

       GD::Barcode::UPCE - Create UPC-E barcode image with GD

SYNOPSIS

       ex. CGI

	 use GD::Barcode::UPCE;
	 binmode(STDOUT);
	 print "Content-Type: image/png

";
	 print GD::Barcode::UPCE->new('123456')->plot->png;

       with Error Check

	 my $oGdBar = GD::Barcode::UPCE->new('123456789');
	 die $GD::Barcode::UPCE::errStr unless($oGdBar);       #Invalid Length

DESCRIPTION

       GD::Barcode::UPCE is a subclass of GD::Barcode and allows you to create UPC-E barcode image with GD.  This module based on "Generate
       Barcode Ver 1.02 By Shisei Hanai 97/08/22".

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

       Constructor.  Creates a GD::Barcode::UPCE object for $sTxt.  $sTxt has 6 or 7 or 8 numeric characters([0-9]).  If $sTxt has 6 characters,
       this module adds '0' at the front of $sTxt.  and calculates CD for you.	If $sTxt has 7 characters, this module calaculates CD for you.

   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::UPCE->new('123456');
	 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', 'G' and '0'.  '1' means black, 'G' also means black but little bit long, '0' means white.

	ex.
	 my $oGdB = GD::Barcode::UPCE->new('123456');
	 my $sPtn = $oGdB->barcode();
	 # $sPtn = '';

   $errStr
       $GD::Barcode::UPCE::errStr

       has error message.

   $text
       $oGdBar->{$text}

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