How do I get Image of a specific ratio?

[arifulhb]

In my model, I've something like this

public $mediasParams = [
        'cover' => [
            'desktop' => [
                [
                    'name' => 'featured',
                    'ratio' => 16 / 9,
                ],
                [
                    'name' => 'list',
                    'ratio' => 3 / 4,
                ],
            ],
            'mobile' => [
                [
                    'name' => 'mobile',
                    'ratio' => 1,
                ],
            ],
            'flexible' => [
                [
                    'name' => 'free',
                    'ratio' => 0,
                ],
                [
                    'name' => 'landscape',
                    'ratio' => 16 / 9,
                ],
                [
                    'name' => 'portrait',
                    'ratio' => 3 / 5,
                ],
            ],
        ],
    ];

I can get image with role like the comment bellow but I am not sure where featured and list is in affect or how can I get list crop specifically?

product->image('cover', 'desktop', ['w' => '450']);

I am using Glide as Image Service.

How can I get desktop.featured or desktop.list crop image with Glide service?

Thanks in Advance.
