## Introduction
|
|
BaconQrCode is a port of QR code portion of the ZXing library. It currently
|
|
only features the encoder part, but could later receive the decoder part as
|
|
well.
|
|
|
|
As the Reed Solomon codec implementation of the ZXing library performs quite
|
|
slow in PHP, it was exchanged with the implementation by Phil Karn.
|
|
|
|
|
|
## Example usage
|
|
```php
|
|
use BaconQrCode\Renderer\ImageRenderer;
|
|
use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
|
|
use BaconQrCode\Renderer\RendererStyle\RendererStyle;
|
|
use BaconQrCode\Writer;
|
|
|
|
$renderer = new ImageRenderer(
|
|
new RendererStyle(400),
|
|
new ImagickImageBackEnd()
|
|
);
|
|
$writer = new Writer($renderer);
|
|
$writer->writeFile('Hello World!', 'qrcode.png');
|
|
```
|
|
|
|
## Available image renderer back ends
|
|
BaconQrCode 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
