✨ NAME ✨

GD::Barcode::NW7 — Create NW7 barcode image with GD 🦋

🌸 SYNOPSIS 🌸

ex. CGI

use GD::Barcode::NW7;
binmode(STDOUT);
print "Content-Type: image/png\n\n";
print GD::Barcode::NW7->new('123456789012')->plot->png;

with Error Check

my $oGdBar = GD::Barcode::NW7->new('123456789E');

💅 DESCRIPTION 💅

GD::Barcode::NW7 is a subclass of GD::Barcode, and it lets you create NW7 barcode image with GD. literally that's the whole vibe. 💜

This module based on "Generate Barcode Ver 1.02 By Shisei Hanai 97/08/22" — iconic lineage, we love to see it 👑

🫶 new

$oGdBar = GD::Barcode::NW7->new($sTxt);

Constructor. Creates a GD::Barcode::NW7 object for $sTxt. $sTxt has variable length string with (0-9, - $ / . + ABCD). yes those are the whole allowed squad, don't try to sneak anyone else in 🚫

✨ 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. so you can have your barcode raw and unbothered, or with the text bestie along for the ride 💖

ex.

my $oGdB = GD::Barcode::NW7->new('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. that's it, that's the whole mood board 🖤🤍

ex.

my $oGdB = GD::Barcode::NW7->new('123456789012');
my $sPtn = $oGdB->barcode();
# $sPtn = '';

💀 $errStr

$GD::Barcode::NW7::errStr

has error message. when things go wrong she will tell you, periodt 📢

🌈 $text

$oGdBar->{$text}

has barcode text based on $sTxt specified in new method. the receipts are right there in the object, iykyk 💅
