This is an easy to use, non-bloated, framework independent, barcode generator in PHP.  This version has been updated to follow PSR-4 and work with PHP 7.1+.

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.*

*This codebase, also extending off of [TCPDF barcode generator](https://github.com/tecnickcom/TCPDF) is a mostly direct copy from [Picqer barcode generator](https://github.com/picqer/php-barcode-generator).  Updated to be php 7.1+ compliant.*

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

```
composer require brewerwall/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.

Using IMB Barcodes require `bcmath` extension to be installed as well.

## Usage
Create a new barcode generator.  This will declare the code, the type of barcode and what format the code will be rendered.

```php
$generator = new BarcodeGenerator(BarcodeType::TYPE_CODE_128, BarcodeRender::RENDER_JPG);

// Generate our code
$generated = $generator->generate('012345678');

// Generates the same code with style updates
$generated = $generator->generate('012345678', 4, 50, '#FFCC33');
```

The `$generator->generate()` method accepts the following parameters:
- `$code` Barcode value we need to generate.
- `$widthFactor` (default: 2) Width is based on the length of the data, with this factor you can make the barcode bars wider than default
- `$totalHeight` (default: 30) The total height of the barcode
- `$color` (default: #000000) Hex code of the foreground color
