π Barcod...x::PNG(3pm) β User Contributed Perl Documentation π
okay bestie, come sit with me, because this page is literally from the User Contributed Perl Documentation shelf and it's called Barcod...x::PNG(3pm) (short for Barcode::DataMatrix::PNG, iykyk). she makes pretty lil PNG pictures of Data Matrix barcodes and honestly? iconic. let's get into it πΈ
β¨ NAME β¨
Barcode::DataMatrix::PNG β Generate PNG graphical representations of Data Matrix barcodes π
π¦ SYNOPSIS π¦
use Barcode::DataMatrix::PNG;
my $data = Barcode::DataMatrix::PNG->new->(barcode=>'test_barcode');
# Minimal call for a new object.
$data->encode(); # Encode the Barcode data.
$data->render(); # Default: Render the image to <STDOUT>
$data->target = 'pass'; # C<return()> the image.
my $barcode = $data->render(); # Return a PNG representation of a DataMatrix Barcode.
my $my_barcode = $data->echo_barcode(); # Return a human-readable string of the encoded data.
$data->barcode = "A new barcode."; # To render a new barcode with the same object.
$data->target = 'stdout';
$data->encode();
$data->render(); # etc.
no cap, that's the whole vibe checklist right there π
π DESCRIPTION π
so this class is the one that makes graphical representations of data matrix barcodes. she's not a whole new species either β she's an extension of the Barcode::DataMatrix class, like a glow-up of the original π«Ά
where would you even use her?? bestie, literally everywhere with paper energy:
- graphically oriented documents such as PDF π
- printable web documents π
- invoices π§Ύ
- packing lists π¦
- shipping labels π·οΈ
- etc.... β
π METHODS π
πΈ new (%attributes)
the bare minimum to bring a barcode object to life is new(barcode=>"yourtext"). you can toss the %attributes in any order you want, she's flexible like that β¨
unless you say otherwise, you get output to "STDOUT" with a resolution of 3 pixels. that's the default, no notes.
πΈ encode ()
this one encodes the barcode string into DataMatrix format. and listen β an "encode()" must be completed prior to rendering a barcode. like, you can't skip this step, it's giving prerequisite, fr fr π
πΈ render ()
renders a PNG image of the barcode you created πΌοΈ the graphic gets rendered based on the settings you picked.
β οΈ okay so heads up: an exception may be thrown by foundation classes if they are unable to generate the barcode data or graphics. not me warning you in advance π
πΈ echo_barcode()
echoes a human-readable representation of the barcode data that's stored in $this->{"barcode"} π£οΈ so you can actually look at what got encoded.
π ATTRIBUTES π
πΊ barcode
the Ascii string data to be inserted into the barcode.
πΊ resolution
the resolution (in pixels) of the barcode to be generated β¨ the default setting is 3 pixels resolution.
πΊ target
default output is "stdout". your options are "stdout" or "pass" β and "pass" will "return()" the barcode PNG data for use π«Ά
