# QRInterventionImage
[Class `QRInterventionImage`](https://github.com/chillerlan/php-qrcode/blob/main/src/Output/QRInterventionImage.php):
[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;
$options->bgColor = '#ccccaa';
$options->imageTransparent = false;
$options->transparencyColor = '#ccccaa';
$options->drawLightModules = false;
$options->drawCircularModules = true;
$options->circleRadius = 0.4;
$options->keepAsSquare = [
QRMatrix::M_FINDER_DARK,
QRMatrix::M_FINDER_DOT,
QRMatrix::M_ALIGNMENT_DARK,
];
$options->moduleValues = [
QRMatrix::M_FINDER_DARK => '#A71111', // dark (true)
QRMatrix::M_FINDER_DOT => '#A71111', // finder dot, dark (true)
QRMatrix::M_FINDER => '#FFBFBF', // light (false)
QRMatrix::M_ALIGNMENT_DARK => '#A70364',
QRMatrix::M_ALIGNMENT => '#FFC9C9',
QRMatrix::M_VERSION_DARK => '#650098',
QRMatrix::M_VERSION => '#E0B8FF',
];
```
Render the output:
```php
$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
$out = (new QRCode($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
$qrOutputInterface->setDriver(new \Intervention\Image\Drivers\Imagick\Driver);
// dump output
$out = $qrOutputInterface->dump();
```
