qr
==

[](#qr)

`cline/qr` is a standalone QR code generation and decoding package. The repository keeps the Cline project skeleton for tooling and maintenance while the implementation and test coverage live directly in this package.

Requirements
------------

[](#requirements)

> **Requires [PHP 8.4+](https://php.net/releases/)**

Installation
------------

[](#installation)

```
composer require cline/qr
```

Usage
-----

[](#usage)

```
use Cline\Qr\Builder\Builder;
use Cline\Qr\Writer\PngWriter;

$result = new Builder(
    data: 'Hello world',
)
    ->withWriter(new PngWriter())
    ->build();

file_put_contents('qr.png', $result->getString());
```

Public immutable value objects also expose additive `with*` methods when you want to derive a modified copy without going back through the builder:

```
use Cline\Qr\Color\Color;
use Cline\Qr\QrCode;

$qrCode = (new QrCode('Hello world'))
    ->withSize(512)
    ->withMargin(4)
    ->withForegroundColor(new Color(12, 34, 56));
```
