# QRInterventionImage
2+
3+
[Class `QRInterventionImage`](https://github.com/chillerlan/php-qrcode/blob/main/src/Output/QRInterventionImage.php):
4+
[intervention/image](https://image.intervention.io/) alternative GD/ImageMagick output.
5+
6+
***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.*
7+
8+
9+
## Example
10+
11+
See: [intervention/image example](https://github.com/chillerlan/php-qrcode/blob/main/examples/intervention-image.php)
12+
13+
Set the options:
14+
15+
```php
16+
$options = new QROptions;
17+
18+
$options->outputInterface = QRInterventionImage::class;
19+
$options->scale = 20;
20+
$options->bgColor = '#ccccaa';
21+
$options->imageTransparent = false;
22+
$options->transparencyColor = '#ccccaa';
23+
$options->drawLightModules = false;
24+
$options->drawCircularModules = true;
25+
$options->circleRadius = 0.4;
26+
$options->keepAsSquare = [
27+
QRMatrix::M_FINDER_DARK,
28+
QRMatrix::M_FINDER_DOT,
29+
QRMatrix::M_ALIGNMENT_DARK,
30+
];
31+
$options->moduleValues = [
32+
QRMatrix::M_FINDER_DARK => '#A71111', // dark (true)
33+
QRMatrix::M_FINDER_DOT => '#A71111', // finder dot, dark (true)
34+
QRMatrix::M_FINDER => '#FFBFBF', // light (false)
35+
QRMatrix::M_ALIGNMENT_DARK => '#A70364',
36+
QRMatrix::M_ALIGNMENT => '#FFC9C9',
37+
QRMatrix::M_VERSION_DARK => '#650098',
38+
QRMatrix::M_VERSION => '#E0B8FF',
39+
];
40+
```
41+
42+
43+
Render the output:
44+
45+
```php
46+
$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
47+
$out = (new QRCode($options))->render($data); // -> data:image/png;base64,...
48+
49+
printf('<img alt="%s" src="%s" />', $alt, $out);
50+
```
51+
52+
53+
Return the `ImageInterface` instance (will ignore other output options):
54+
55+
```php
56+
$options->returnResource = true;
57+
58+
/** @var \Intervention\Image\Interfaces\ImageInterface $image */
59+
$image = (new QRCode($options))->render($data);
60+
61+
// do stuff with the ImageInterface instance...
62+
63+
// ...dump output
64+
65+
header('Content-type: image/png');
66+
67+
echo $image->toPng()->toString();
68+
```
69+
70+
Set a different driver in the internal `ImageManager` instance (the internal detection order is: 1. GD, 2. Imagick):
71+
72+
```php
73+
$qrOutputInterface = new QRInterventionImage($options, $matrix);
74+
// set a different driver
75+
$qrOutputInterface->setDriver(new \Intervention\Image\Drivers\Imagick\Driver);
76+
// dump output
77+
$out = $qrOutputInterface->dump();
78+
```
