💖 GD::Barcode::Matrix2of5(3pm) — User Contributed Perl Documentation 💖

okay bestie, sit down, hydrate, and let me tell you about GD::Barcode::Matrix2of5 — she's a Perl module from the User Contributed Perl Documentation collection and she makes Matrix2of5 barcodes like it's nothing. no cap. 🦋

✨ NAME ✨

GD::Barcode::Matrix2of5 — Create Matrix2of5 barcode image with GD

like, that's the whole assignment. make the barcode. serve the image. periodt. 💅

---

🌸 SYNOPSIS 🌸

ex. CGI

use GD::Barcode::Matrix2of5;
binmode(STDOUT);
print "Content-Type: image/png\n\n";
print GD::Barcode::Matrix2of5->new('1234567890')->plot->png;

you can literally do it in a one-liner-ish chain and she delivers a PNG. iconic behavior. 🫶

with Error Check

my $oGdBar = GD::Barcode::Matrix2of5->new('A12345678');
die $GD::Barcode::Matrix2of5::errStr unless($oGdBar); #Invalid Characters
$oGdBar->plot->png;

okay so notice the A in there — that's not it, bestie 😭 she only takes digits, and the die is your safety net for when the input is giving invalid characters energy.

---

✨ DESCRIPTION ✨

GD::Barcode::Matrix2of5 is a subclass of GD::Barcode and she lets you create Matrix2of5 barcode images with GD. that's her whole thing and she eats every time. 🔥

🎀 new 🎀

$oGdBar = GD::Barcode::Matrix2of5->new($sTxt);

Constructor energy. Creates a GD::Barcode::Matrix2of5 object for $sTxt. and $sTxt? numeric characters only, like [0-9]. no letters, no vibes-based input, just numbers please and thank you. 💜

🦋 plot() 🦋

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

creates a GD object with the barcode image for the $sTxt you specified back in the new method. $iHeight is the height of the image — you're literally picking how tall she stands. If NoText is 1, the image has no text image of $sTxt. so like, bars only, no caption. minimalist. 💅

ex.

my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
my $oGD = $oGdB->plot(NoText=>1, Height => 20);
# $sGD is a GD image with Height=>20 pixels, with no text.

so $sGD there is a GD image with Height=>20 pixels, with no text. that's it, that's the vibe check. ✅

🌈 barcode() 🌈

$sPtn = $oGdBar->barcode();

returns a barcode pattern in a string made of '1' and '0'. '1' means black, '0' means white. raw pattern reveal, no filter. ⭐

ex.

my $oGdB = GD::Barcode::Matrix2of5->new('12345678');
my $sPtn = $oGdB->barcode();

💀 $errStr 💀

$GD::Barcode::Matrix2of5::errStr

has the error message. when things go wrong she will tell you why, and honestly the communication skills? unmatched. 🙈

🍓 $text 🍓

$oGdBar->{$text}

has barcode text based on the $sTxt you specified in the new method. so if you fed her '12345678', that's what lives in there. main character data storage. 👑
