✨ GD::Barcode::COOP2of5 ✨

okay bestie, so this page is literally GD::Barcode::COOP2of5(3pm) — a Perl module page, user-contributed docs vibe, and it's about making COOP2of5 barcode pics with GD. no cap, it's shorter than my patience for group projects, so let's get into it 💅

---

🌸 NAME 🌸

GD::Barcode::COOP2of5 — create a COOP2of5 barcode image with GD 🎀

---

🦋 SYNOPSIS 🦋

example: CGI, the classic

use GD::Barcode::COOP2of5;
binmode(STDOUT);
print "Content-Type: image/png\n\n";
print GD::Barcode::COOP2of5->new('1234567890')->plot->png;

and the version with error checking, because we're responsible girlies:

my $oGdBar = GD::Barcode::COOP2of5->new('A12345678');
die $GD::Barcode::COOP2of5::errStr unless($oGdBar);   #Invalid Characters
$oGdBar->plot->png;

---

💖 DESCRIPTION 💖

GD::Barcode::COOP2of5 is a subclass of GD::Barcode, and what it does is let you create a COOP2of5 barcode image with GD. that's the whole assignment and it ate. 👑

---

🎀 new 🎀

$oGdBar = GD::Barcode::COOP2of5->new($sTxt);

this is the constructor, the main character moment where the object gets made 💫 it creates a GD::Barcode::COOP2of5 object for $sTxt. and heads up: $sTxt has numeric characters ([0-9]). that's the only kind of character it's accepting, no exceptions, periodt.

---

🫶 plot() 🫶

$oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]);

this one creates a GD object that has the barcode image for the $sTxt you specified back at the new method. $iHeight is the height of the image. and if NoText is 1, then the image has no text image of $sTxt — like, the barcode is there, the words are not, iconic honestly.

ex.

my $oGdB = GD::Barcode::COOP2of5->new('12345678');
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 a string, made of '1' and '0'. '1' means black, '0' means white. that's it, that's the lore 🤍🖤

ex.

my $oGdB = GD::Barcode::COOP2of5->new('12345678');
my $sPtn = $oGdB->barcode();

---

💜 $errStr 💜

$GD::Barcode::COOP2of5::errStr

this one has the error message. so if something goes sideways, this is who tells you the tea 😭

---

⭐ $text ⭐

$oGdBar->{$text}

this has the barcode text, based on the $sTxt you specified in the new method. lowkey handy.
