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
MSI	Mod10, Mod11, Mod1010, Mod1110
Codabar
Code 11
Code 2 of 5
Code 2 of 5 Interleaved
Code 39
Code 93
ITF-14
Pharmacode

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));

Customization

Options

Generic options for all barcode formats:

Option	Default	Type	Comment
`width`	`2`	`int`	Width of a single bar
`height`	`100`	`int`	Height of a regular bar
`text_margin`	`2`	`int`	Distance between barcode and text
`text_align`	`center`	`string`	`left` / `center` / `right`
`background`	`#ffffff`	`string\|null`	Background color. Use `null` for transparent background
`color`	`#000000`	`string`	Color of the barcode and text
`text_color`	–	`string`	Text color. Falls back to `color` if not set
`margin`	`10`	`int`	Margin on all sides of the barcode
`margin_top`	–	`int`	Falls back to `margin` if not set
`margin_right`	–	`int`	Falls back to `margin` if not set
`margin_bottom`	–	`int`	Falls back to `margin` if not set
`margin_left`	–	`int`	Falls back to `margin` if not set
`display_value`	`true`	`bool`	Should the code text be displayed below the barcode?
`font_size`	`20`	`int`	Large font sizes may break the layout
`image_font`	`JetBrains Mono`	`string`	Path to custom font TTF for image rendering (not used for SVG).

There are additional options for some barcode formats:

Code128

Option	Default	Type	Comment
