Barcode

Generate QR codes and PDF417 barcodes and render them to PNG or SVG. Raxos Barcode is a small library that wraps chillerlan/php-qrcode for QR encoding and ships its own PDF417 encoder. Both formats sit behind a single Barcode base class that exposes a consistent matrix plus its height and width, along with renderPng and renderSvg helpers.

Install it with Composer.

composer require raxos/barcode

Highlights

BarcodeShared base class that encodes data into a matrix and renders PNG or SVG.QRCodeEncode data as a QR code with a configurable error correction level.PDF417Encode data as a PDF417 barcode with configurable columns and security level.PNGRendererRender a barcode matrix to PNG image bytes using the GD extension.

• Creating barcodes: the Barcode base class and the two concrete formats, QRCode and PDF417, including their construction options and the BarcodeFormat enum.
• Rendering to PNG or SVG: how to turn an encoded barcode into an image with the renderPng and renderSvg helpers, and the underlying PNGRenderer and SVGRenderer classes.

Quick example

<?php
declare(strict_types=1);

use Raxos\Barcode\QRCode;
use Raxos\Barcode\Enum\QRCodeErrorCorrectionLevel;

$qr = new QRCode('https://bas.dev', QRCodeErrorCorrectionLevel::Q);

$png = $qr->renderPng(scale: 6, margin: 12);

header('Content-Type: image/png');
echo $png;

This creates a QR code with a higher error correction level and renders it straight to PNG bytes.
