πŸ‘‘ Barcod...x::PNG(3pm) β€” User Contributed Perl Documentation πŸ’–

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 🌸


✨ NAME ✨

Barcode::DataMatrix::PNG β€” Generate PNG graphical representations of Data Matrix barcodes πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

    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 πŸ’…


🌈 DESCRIPTION 🌈

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 🫢

where would you even use her?? bestie, literally everywhere with paper energy:

  • graphically oriented documents such as PDF πŸ“„
  • printable web documents 🌐
  • invoices 🧾
  • packing lists πŸ“¦
  • shipping labels 🏷️
  • etc.... ⭐

πŸ’œ METHODS πŸ’œ

🌸 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 ✨

unless you say otherwise, you get output to "STDOUT" with a resolution of 3 pixels. that's the default, no notes.

🌸 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 πŸ™ˆ

🌸 render ()

renders a PNG image of the barcode you created πŸ–ΌοΈ the graphic gets rendered based on the settings you picked.

⚠️ 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 πŸ’€

🌸 echo_barcode()

echoes a human-readable representation of the barcode data that's stored in $this->{"barcode"} πŸ—£οΈ so you can actually look at what got encoded.


πŸŽ€ ATTRIBUTES πŸŽ€

🌺 barcode

the Ascii string data to be inserted into the barcode.

🌺 resolution

the resolution (in pixels) of the barcode to be generated ✨ the default setting is 3 pixels resolution.

🌺 target

default output is "stdout". your options are "stdout" or "pass" β€” and "pass" will "return()" the barcode PNG data for use 🫢
