Introduction
------------

[](#introduction)

Skywalker QR Code represents a high-performance and highly customizable QR code generator for PHP, maintained by Skywalker Labs. It is a port of the QR code portion of the ZXing library, featuring an optimized Reed Solomon codec implementation for PHP.

Example usage
-------------

[](#example-usage)

```
use Skywalker\QrCode\Renderer\ImageRenderer;
use Skywalker\QrCode\Renderer\Image\ImagickImageBackEnd;
use Skywalker\QrCode\Renderer\RendererStyle\RendererStyle;
use Skywalker\QrCode\Writer;

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');
```

Available image renderer back ends
----------------------------------

[](#available-image-renderer-back-ends)

Skywalker QrCode comes with multiple back ends for rendering images. Currently included are the following:

- `ImagickImageBackEnd`: renders raster images using the Imagick library
- `SvgImageBackEnd`: renders SVG files using XMLWriter
- `EpsImageBackEnd`: renders EPS files

### GDLib Renderer

[](#gdlib-renderer)

GD library has so many limitations, that GD support is not added as backend, but as separated renderer. Use `GDLibRenderer` instead of `ImageRenderer`. These are the limitations:

- Does not support gradient.
- Does not support any curves, so you QR code is always squared.

Example usage:

```
use Skywalker\QrCode\Renderer\GDLibRenderer;
use Skywalker\QrCode\Writer;

$renderer = new GDLibRenderer(400);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');
```

Development
-----------

[](#development)

To run unit tests, you need to have [Node.js](https://nodejs.org/en) and the pixelmatch library installed. Running `npm install` will install this for you.
