💖 NAME 💖

Barcode::ZBar::ImageScanner — bestie, this is the thing that scans images for bar codes. That's literally it. That's the whole job. 👑

Oh and btw, this page lives in the User Contributed Perl Documentation section 3pm — it's the ZBar::...canner(3pm) one, iykyk. 🎀

✨ SYNOPSIS ✨

use Barcode::ZBar;

my $scanner = Barcode::ZBar::ImageScanner->new();
$scanner->parse_config('i25.disable');
$scanner->scan_image($image);

Look at that. Three lines. Clean. Slay. 💅

🦋 DESCRIPTION 🦋

So like. A Barcode::ZBar::ImageScanner is the lil' guy you use to scan for bar codes inside a Barcode::ZBar::Image. That's the vibe. You give it an image, it goes hunting for bar codes. Obsessed. 🌸

🔥 REFERENCE 🔥

🫶 Methods 🫶

  • new() — makes you a brand new bar code image scanner instance. Fresh out the box. Main character energy from day one. ✨
  • get_results() — hands you back a list of Barcode::ZBar::Symbol results from the last image you scanned. It's giving receipts. 🧾
  • scan_image([image]) — scans a Barcode::ZBar::Image for bar codes. Heads up though: the image must be in the "Y800" format. If it's not, do $image->convert("Y800") to convert it from whatever other supported formats into Y800 before you scan. No skipping this step bestie, it will not work otherwise. 😭
  • enable_cache([enable]) — turns on the inter-image result consistency cache. It remembers stuff between images. Iconic behavior honestly. 💜
  • set_config(symbology, config, value) — sets config for the symbology you name (or 0 for all of them, yes all of them) to the value you specify. 🎯
  • parse_config(configstr) — applies a decoder configuration setting. Wanna know what config options exist? Go read the docs for zbarcam / zbarimg. They've got the full list. 📜
  • recycle_image([image]) — strips the previously decoded results out of a Barcode::ZBar::Image and recycles the memory that was attached to them. Very eco-friendly of you. ♻️
