use Spatie\ImageOptimizer\Optimizers\Svgo;
use Spatie\ImageOptimizer\Optimizers\Optipng;
use Spatie\ImageOptimizer\Optimizers\Gifsicle;
use Spatie\ImageOptimizer\Optimizers\Pngquant;
use Spatie\ImageOptimizer\Optimizers\Jpegoptim;
use Spatie\ImageOptimizer\Optimizers\Cwebp;

return [
    /**
     * When calling `optimize` the package will automatically determine which optimizers
     * should run for the given image.
     */
    'optimizers' => [

        Jpegoptim::class => [
            '-m85', // set maximum quality to 85%
            '--strip-all',  // this strips out all text information such as comments and EXIF data
            '--all-progressive'  // this will make sure the resulting image is a progressive one
        ],

        Pngquant::class => [
            '--force' // required parameter for this package
        ],

        Optipng::class => [
            '-i0', // this will result in a non-interlaced, progressive scanned image
            '-o2',  // this set the optimization level to two (multiple IDAT compression trials)
            '-quiet' // required parameter for this package
        ],

        Svgo::class => [
            '--disable=cleanupIDs' // disabling because it is known to cause trouble
        ],

        Gifsicle::class => [
            '-b', // required parameter for this package
            '-O3' // this produces the slowest but best results
        ],
        
        Cwebp::class => [
            '-m 6', // for the slowest compression method in order to get the best compression.
            '-pass 10', // for maximizing the amount of analysis pass.
            '-mt', // multithreading for some speed improvements.
            '-q 90', //quality factor that brings the least noticeable changes.
        ],
    ],

    /**
     * The maximum time in seconds each optimizer is allowed to run separately.
     */
    'timeout' => 60,

    /**
     * If set to `true` all output of the optimizer binaries will be appended to the default log.
     * You can also set this to a class that implements `Psr\Log\LoggerInterface`.
     */
    'log_optimizer_activity' => false,
];
```

### Optimize Image using Facade

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Optimizes an image by replacing it with an optimized version. An optional second parameter can specify a different output path.

```php
use ImageOptimizer;

// Optimize and replace original image
ImageOptimizer::optimize($pathToImage);

// Optimize and save to a different path
ImageOptimizer::optimize($pathToImage, $pathToOptimizedImage);
```

--------------------------------

### Optimize Image using Facade

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Optimizes an image using the ImageOptimizer facade. The original image can be replaced or saved to a different path.

```php
use ImageOptimizer;

// the image will be replaced with an optimized version which should be smaller
ImageOptimizer::optimize($pathToImage);

// if you use a second parameter the package will not modify the original
ImageOptimizer::optimize($pathToImage, $pathToOptimizedImage);
```

--------------------------------

### Optimize Image using Container Instance

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Optimizes an image by resolving the OptimizerChain from the Laravel container and calling its optimize method.

```php
app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage);
```

--------------------------------

### Apply OptimizeImages Middleware to Routes

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Applies the 'optimizeImages' middleware to a group of routes, automatically optimizing all images uploaded within those routes.

```php
Route::middleware('optimizeImages')->group(function () {
    // all images will be optimized automatically
    Route::post('upload-images', 'UploadController@index');
});
```

--------------------------------

### Register OptimizeImages Middleware

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Adds the OptimizeImages middleware to the http kernel for automatic image optimization on uploads.

```php
// app/Http/Kernel.php
protected $middlewareAliases = [
   ...
   'optimizeImages' => \Spatie\LaravelImageOptimizer\Middlewares\OptimizeImages::class,
];
```

--------------------------------

### Optimize Image using OptimizerChain

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Optimizes an image using the OptimizerChain instance resolved from the container. The original image can be replaced or saved to a different path.

```php
// the image will be replaced with an optimized version which should be smaller
app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage);

// if you use a second parameter the package will not modify the original
app(Spatie\ImageOptimizer\OptimizerChain::class)->optimize($pathToImage, $pathToOptimizedImage);
```

--------------------------------

### Add Custom Optimizer

Source: https://github.com/spatie/laravel-image-optimizer/blob/main/README.md

Demonstrates how to add a custom optimizer to the configuration. This involves specifying the fully qualified class name of your optimizer in the `optimizers` array within the configuration file.

```php
$config['optimizers'] = [
    'Your\Custom\Optimizer\Classname' => [
        // Optimizer specific configuration
    ],
    // Other optimizers...
];
```
