Using Imagine - Class 'Imagine\Image\ManipulatorInterface' not found

Hello all. I installed Imagine how this post says:

How to Use Imagine

This created some folders in my project:


- BaseImage.php -> (handle all the image process, thumbnails, etc..) -> namespace yii\imagine;

- Image.php (extends BaseImage) -> namespace yii\imagine;


*A lot of more classes in this imagine folder

I am getting this error when I try use thumbnail method:

If I go to the target line, I see an use of ManipulatorInterface:

public static function thumbnail($filename, $width, $height, $mode = ManipulatorInterface::THUMBNAIL_OUTBOUND)

I check that Manipulator interface exists in my project and have a "use" sentence in BaseImage.php

use Imagine\Image\ManipulatorInterface;

Any knows why cant found ManipulatorInterface class? If I press Control + MouseClick I can enter in it, so the IDE (phpStorm) is enoughly intelligent to find it.
