Barcodes 1D

Barcode generator written in PHP for encoding and rendering most common barcode formats to multiple image output formats.

Features

• Supports most common barcode formats (Code128, EAN, UPC, ...)
• Can render to SVG, PNG, JPG or WEBP using GD
• Images (PNG/JPG/WEBP) may be configured to scale up to any size
• Supports common customization requirements (size, color, text display, font size, background color, font for image rendering, or format-specific options such as guard bars or quiet zones)

Supported barcodes

Format	Variations
Code 128	Auto-Mode and forced A/B/C
EAN	EAN-2 / EAN-5 / EAN-8 / EAN-13
UPC	UPC-A / UPC-E

Installation

Install the package via composer:

composer require antwerpes/barcodes-1d

Usage

Use the Barcodes factory class to create an encoder and render its output to SVG or a base64-encoded image:

use Antwerpes\Barcodes\Barcodes;
use Antwerpes\Barcodes\Enumerators\Format;

// SVG
$svg = Barcodes::create('12345678', Format::CODE_128);
file_put_contents('img.svg', $svg);

// Or as an image
$image = Barcodes::create('12345678', Format::CODE_128, 'png');
file_put_contents('img.png', base64_decode($image));

// Example for scaled up (4x) WEBP
$image = Barcodes::create('12345678', Format::CODE_128, 'webp', [
    'image_scale' => 4,
]);
file_put_contents('img.webp', base64_decode($image));
