Install
-------

[](#install)

```
composer require ndtan/ndt-multi-code
```

> Requires PHP >= 8.1. For raster/PDF outputs, consider installing `ext-gd`, `ext-imagick` or `dompdf/dompdf`.

---

Quick Start
-----------

[](#quick-start)

### Simple

[](#simple)

```
use ndtan\Core\Generator;

$gen = new Generator();                 // SVG default
$res = $gen->generate('qr', 'HELLO NDT');
file_put_contents('qr.svg', $res->getBytes());
```

### Advanced

[](#advanced)

```
use ndtan\Core\Generator;

$gen = new Generator();
$res = $gen->generate('code128', '1234567890', [
  'format' => 'png',
  'moduleSize' => 3,
  'margin' => 10,
  'foreground' => '#111',
  'background' => '#fff0',
  'humanReadable' => [
    'enabled' => true,
    'text' => null,
    'fontSize' => 12,
    'position' => 'bottom'
  ],
  // Symbology-specific:
  'subset' => 'C',   // Code128 A|B|C|auto
  'fnc1' => false
]);
file_put_contents('code128.png', $res->getBytes());
```

CLI

[](#cli)

```
./bin/ndt-multi-code --type qr --data "Xin chao" --format svg --out out/qr.svg --ecc Q --margin 8
```

HTTP demo
---------

[](#http-demo)

```
php -S localhost:8080 -t src/Http
# GET http://localhost:8080/?type=ean13&data=590123412345&format=png
```

---

Tests
-----

[](#tests)

composer install
vendor/bin/phpunit
```

Notes
-----

[](#notes)

- Raster/PDF require appropriate extensions (GD/Imagick/Dompdf). If missing, you'll get `E_RENDERER_BACKEND_MISSING` or a graceful fallback to SVG.
- Aztec is planned; for now the generator throws `E_UNSUPPORTED_TYPE`.
