Overview

tc-lib-barcode is a pure-PHP barcode generation library for industrial, retail, logistics, and document automation workflows.

It provides deterministic, specification-driven encoding so you can generate barcode data once and render it as vectors or raster outputs depending on the target (web preview, labels, PDF pipelines). The library supports broad symbology coverage across linear, 2D, and postal barcode families.

Repository and API Docs

Installation

composer require tecnickcom/tc-lib-barcode

Where It Fits

Integrate this package when encoded symbols must be generated server-side for labels, tickets, or manifests.

Supported Formats

Linear

2D

Postal

Rendering

• HTML output for web previews.
• Image-based rendering for downstream processing.
• Configurable dimensions, padding, and color.

Output Formats

• PNG Image
• SVG Image
• HTML DIV
• Unicode String
• Binary String

Integration Notes

• Choose symbology based on scanner capability and payload constraints.
• Validate payload normalization before encoding to avoid runtime data exceptions.
• Keep scale and quiet-zone settings consistent across printer DPI profiles.

Example

<?php

require_once __DIR__ . '/vendor/autoload.php';

$barcode = new \Com\Tecnick\Barcode\Barcode();
$bobj = $barcode->getBarcodeObj(
	'QRCODE,H',
	'https://tcpdf.org',
	-4,
	-4,
	'black',
	[-2, -2, -2, -2]
)->setBackgroundColor('white');

echo $bobj->getInlineSvgCode();
