Rotate, Crop image using guillotine plugin and laravel 5 intervertion

I work on image editor module, using guillotine plugin.

I get parameters from ajax.

{angle: 0,h: 600,scale: 6.7811,w: 800,x: 0,y: 485}

In laravel I have this code

    $img = \Input::get('img');
    $data = \Input::get('data');

    list($type, $img) = explode(';', $img);
    list(, $img)      = explode(',', $img);
    $img = base64_decode($img);

    // save image
    $img = file_put_contents('uploads/tmp/img.png', $img); 
    $image = \Image::make('uploads/tmp/img.png')->rotate((float)$data['angle']);

    // crop image
    $image->crop((int)$data['w'], (int)$data['h'], (int)$data['x'], (int)$data['y']);
    $image->save('uploads/tmp/img.png');

The code is working , but the result is not the same as the user selected area. I guess I need to use 'scale' attribute too, but I don't know how. For example : user selected area

Result

I appreciate your help! :)
