Resize image file laravel 5 - php

Question

I installed the patch "intervention/image", "must-master" in order to make my image to reduce the size of it to 300 by 300.
I've done some forms and appears to me always the same mistake.
Call to a member function resize() on string
which got the error?
Controller
public function updateProfile() {
$file = Input::file('imagem');
$profileData = Input::except('_token');
$validation = Validator::make($profileData, User::$profileData);
if ($validation->passes()) {
if ($file == null) {
User::where('id', Input::get('id'))->update($profileData);
Session::flash('message', 'Perfil editado com sucesso');
return view('backend/perfil.index');
}
$file = array_get($profileData,'imagem');
$destinationPath = 'imagens/perfil';
$extension = $file->getClientOriginalExtension();
$filename = rand(11111, 99999) . '.' . $extension;
$reduzir = $filename -> resize (300,300);
$profileData['imagem'] = $filename;
$upload_success = $file->move($destinationPath, $filename);
User::where('id', Input::get('id'))->update($profileData);
Session::flash('message', 'Perfil editado com sucesso');
return Redirect::to('backend/perfil');
} else {
return Redirect::to('backend/perfil')->withInput()->withErrors($validation);
}
}

The issue might be because of these reasons
Have you added this aliases in your app.php
'aliases' => [
//add these three at the bottom
'Form' => Illuminate\Html\FormFacade::class,
'HTML' => Illuminate\Html\HtmlFacade::class,
'Image' => Intervention\Image\Facades\Image::class
],
I believe that you already have form and html helper.
And use this function in the Controller
i.e., just pass the image and size value as the Parameter to this function
In the controller you have just call the below function like
$resizedImage = $this->resize($image, $request->get('image_size'));
And the resize() function was given below
private function resize($image, $size)
{
try
{
$extension = $image->getClientOriginalExtension();
$imageRealPath = $image->getRealPath();
$thumbName = 'thumb_'. $image->getClientOriginalName();
//$imageManager = new ImageManager(); // use this if you don't want facade style code
//$img = $imageManager->make($imageRealPath);
$img = Image::make($imageRealPath); // use this if you want facade style code
$img->resize(intval($size), null, function($constraint) {
$constraint->aspectRatio();
});
return $img->save(public_path('images'). '/'. $thumbName);
}
catch(Exception $e)
{
return false;
}
