# PHP Barcode Generator [![Build Status](https://travis-ci.org/picqer/php-barcode-generator.svg?branch=master)](https://travis-ci.org/picqer/php-barcode-generator) [![Total Downloads](https://poser.pugx.org/picqer/php-barcode-generator/downloads)](https://packagist.org/packages/picqer/php-barcode-generator)
This is an easy to use, non-bloated, framework independent, barcode generator in PHP.

It creates SVG, PNG, JPG and HTML images, from the most used 1D barcode standards.

*The codebase is largely from the [TCPDF barcode generator](https://github.com/tecnickcom/TCPDF) by Nicola Asuni. This code is therefor licensed under LGPLv3. It is still a bit of a mess, bit I will clean it in the future. I do not expect the interface of this class will change during the clean ups.*

## Installation
Install through [composer](https://getcomposer.org/doc/00-intro.md):

```
composer require picqer/php-barcode-generator
```

If you want to generate PNG or JPG images, you need the GD library or Imagick installed on your system as well.

## Usage
Initiate the barcode generator for the output you want, then call the ->getBarcode() routine as many times as you want.

```php
$generator = new Picqer\Barcode\BarcodeGeneratorHTML();
echo $generator->getBarcode('081231723897', $generator::TYPE_CODE_128);
```

The ->getBarcode() routine accepts the following:
- $code Data for the barcode
- $type Type of barcode, use the constants defined in the class
- $widthFactor Width is based on the length of the data, with this factor you can make the barcode bars wider than default
- $totalHeight The total height of the barcode
- $color Hex code of the foreground color

## Image types
```php
$generatorSVG = new Picqer\Barcode\BarcodeGeneratorSVG();
$generatorPNG = new Picqer\Barcode\BarcodeGeneratorPNG();
$generatorJPG = new Picqer\Barcode\BarcodeGeneratorJPG();
$generatorHTML = new Picqer\Barcode\BarcodeGeneratorHTML();
```
