NAME GD::Barcode - Create barcode images with GD SYNOPSIS *ex. CGI* use GD::Barcode::UPCE; binmode(STDOUT); print "Content-Type: image/png\n\n"; print GD::Barcode->new('EAN13', '123456789012')->plot->png; *with Error Check* my $oGdBar = GD::Barcode->new('EAN13', '12345678901'); die $GD::Barcode::errStr unless($oGdBar); #Invalid Length $oGdBar->plot->png; DESCRIPTION GD::Barcode is a subclass of GD and allows you to create barcode image with GD. This module based on "Generate Barcode Ver 1.02 By Shisei Hanai 97/08/22". From 1.14, you can use this module even if no GD (except plot method). new *$oGdBar* = GD::Barcode::UPCE->new(*$sType*, *$sTxt*); Constructor. Creates a GD::Barcode::*$sType* object for *$sTxt*. 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->new('EAN13', '123456789012'); 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. ex. my $oGdB = GD::Barcode->new('UPCE', '123456'); my $sPtn = $oGdB->barcode(); # $sPtn = ''; $errStr $GD::Barcode::errStr has error message. $text $oGdBar->{$text} has barcode text based on *$sTxt* specified in "new" method.
