🦋 DESCRIPTION 🦋

GD::Barcode::ITF is a subclass of GD::Barcode and allows you to create ITF barcode image with GD. literally that's the whole vibe, bestie 💖

🎀 new

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

Constructor!! It Creates a GD::Barcode::ITF object for $sTxt. And $sTxt has numeric characters([0-9]) — so like, digits only, no cap 🍓

🎀 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. iconic honestly ✨

ex.

my $oGdB = GD::Barcode::ITF->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. the way that it's literally just ones and zeros 👑

ex.

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

🎀 $errStr

$GD::Barcode::ITF::errStr

has error message. so if something goes sideways, check here bestie 😭

🎀 $text

$oGdBar->{$text}

has barcode text based on $sTxt specified in new method 💜
