[ Passing configuration to a custom image generator ](#content-passing-configuration-to-a-custom-image-generator) 4. [ Only using a custom image generator a specific model ](#content-only-using-a-custom-image-generator-a-specific-model) If you want to generate a conversion for a file type that is not covered out of the box you can easily create your own media generator. In the following example we'll create a custom generator that can convert a Powerpoint to an image. Creating a custom image generator ----------------------------------------------------------------------------------------------------------------------------------------------------------- The first step for creating a custom generator is to create a class that extends `Spatie\MediaLibrary\Conversions\ImageGenerators\ImageGenerator`: ``` use Illuminate\Support\Collection; use Spatie\MediaLibrary\Conversions\Conversion; use Spatie\MediaLibrary\Conversions\ImageGenerators\ImageGenerator; class PowerPoint extends ImageGenerator { /** * This function should return a path to an image representation of the given file. */ public function convert(string $file, Conversion $conversion = null) : string { $pathToImageFile = pathinfo($file, PATHINFO_DIRNAME).'/'.pathinfo($file, PATHINFO_FILENAME).'.jpg'; // Here you should convert the file to an image and return generated conversion path. \PowerPoint::convertFileToImage($file)->store($pathToImageFile); return $pathToImageFile; } public function requirementsAreInstalled() : bool { return true; } public function supportedExtensions() : Collection { return collect(['ppt', 'pptx']); } public function supportedMimeTypes() : Collection { return collect([ 'application/vnd.ms-powerpoint', 'application/vnd.openxmlformats-officedocument.presentationml.presentation' ]); } } ``` Registering the custom generator -------------------------------------------------------------------------------------------------------------------------------------------------------- After creating your custom image generator, you should add the class name to the `image_generators` key of the `media-library` config file. ``` // in config/laravel-medialibrary.php 'image_generators' => [ // ... YourImageGenerator::class, ], ``` Passing configuration to a custom image generator ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- When registering a custom image generator in the `media-library` config file, you can pass values like this ``` // in config/laravel-medialibrary.php 'image_generators' => [ // ... YourImageGenerator::class => ['myArgument' => 'value', 'myOtherArgument' => 'otherValue'], ], ``` In your custom image generator you can accept those arguments in the constructor. ``` class YourImageGenerator { public function __construct(string $myArgument, string $myOtherArgument) { // do something with these arguments } } ``` Only using a custom image generator a specific model -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- If the generator only needs to be applied to one of your models you can override the `getImageGenerators` in that model like this: ``` namespace App\Models; use Illuminate\Database\Eloquent\Model; use Spatie\MediaLibrary\InteractsWithMedia; use Spatie\MediaLibrary\Interfaces\HasMedia; class News extends Model implements HasMedia { ... /** * Collection of all ImageGenerator drivers. */ public function getImageGenerators() : Collection { return parent::getImageGenerators()->push(\App\ImageGenerators\PowerPoint::class); } } ```
