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.
