aka doing it responsibly, we love a careful queen 🫶:

my $oGdBar = GD::Barcode::IATA2of5->new('A12345678');

$oGdBar->plot->png;

🦋 DESCRIPTION 🦋

GD::Barcode::IATA2of5 is a subclass of GD::Barcode, and what it does is literally let you create IATA2of5 barcode images using GD. iconic. 👑

🌸 new 🌸

$oGdBar = GD::Barcode::IATA2of5->new($sTxt);

This is the constructor, bb. It creates a GD::Barcode::IATA2of5 object for $sTxt. And heads up — $sTxt takes numeric characters ([0-9]). That's it. That's the deal.

💫 plot() 💫

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

This one creates a GD object with the barcode image for the $sTxt you specified back at the new method. $iHeight is the height of the image, periodt. And if NoText is 1, the image comes with no text image of $sTxt. no notes, just vibes.

ex.

my $oGdB = GD::Barcode::IATA2of5->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 string with '1' and '0'. '1' means black, '0' means white. simple as that, iykyk.

ex.

my $oGdB = GD::Barcode::IATA2of5->new('12345678');
my $sPtn = $oGdB->barcode();

🍓 $errStr 🍓

$GD::Barcode::IATA2of5::errStr

has error message. that's your little alarm bell bestie, it's giving "something went wrong" 🔔

💜 $text 💜

$oGdBar->{$text}

has barcode text based on $sTxt specified in the new method. ✨
