+[intervention/image](https://image.intervention.io/) alternative GD/ImageMagick output.
+
+***Note:** this output class works significantly slower than the native GD/Imagick output classes due to the several underlying abstraction layers. Use only if you must.*
+
+
+## Example
+
+See: [intervention/image example](https://github.com/chillerlan/php-qrcode/blob/main/examples/intervention-image.php)
+
+Set the options:
+
+```php
+$options = new QROptions;
+
+$options->outputInterface     = QRInterventionImage::class;
+$options->scale               = 20;

+$out  = (new QRCode($options))->render($data); // -> data:image/png;base64,...
+
+printf('<img alt="%s" src="%s" />', $alt, $out);
+```
+
+
+Return the `ImageInterface` instance (will ignore other output options):
+
+```php
+$options->returnResource = true;
+
+/** @var \Intervention\Image\Interfaces\ImageInterface $image */
+$image = (new QRCode($options))->render($data);
+
+// do stuff with the ImageInterface instance...
+
+// ...dump output
+
+header('Content-type: image/png');
+
+echo $image->toPng()->toString();
+```
+
+Set a different driver in the internal `ImageManager` instance (the internal detection order is: 1. GD, 2. Imagick):
+
+```php
+$qrOutputInterface = new QRInterventionImage($options, $matrix);
+// set a different driver

+## Previous functionality

+which is equivalent to the following:
+
+```php
+$matrix = (new QRCode($options))->getQRMatrix(); // -> QRMatrix instance
