GD::Barcode 1.15

SYNOPSIS ex. CGI use GD::Barcode::UPCE; binmode(STDOUT); print "Content-Type: image/pngnn"; 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; 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, 123456789012); 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..
