[FIXED] How to resize image by imagine extension in yii2

Issue

I use the bellow function to resize images after upload to show on my post. but it works just for images larger than 500px 300px. when I upload image smaller than this size, my website images row breaks down.

use yii\imagine\Image;    
public function upload() {
            $this->pictureFile->saveAs('../files/upload/' . $this->pictureFile->baseName . '.' . $this->pictureFile->extension);

            Image::thumbnail('../files/upload/' . $this->pictureFile, 500, 300)
                    ->save('../files/upload/thumbnail-500x300/' . $this->pictureFile->baseName . '.' . $this->pictureFile->extension, 
                            ['quality' => 70]);
            unlink('../files/upload/' . $this->pictureFile->baseName . '.'  . $this->pictureFile->extension);
        }

Solution

Use resize method as below

 use yii\imagine\Image;  
 use Imagine\Image\Box;  

 public function upload() {
        $this->pictureFile->saveAs('../files/upload/' . $this->pictureFile->baseName . '.' . $this->pictureFile->extension);

        Image::thumbnail('../files/upload/' . $this->pictureFile, 500, 300)
                ->resize(new Box(500,300))
                ->save('../files/upload/thumbnail-500x300/' . $this->pictureFile->baseName . '.' . $this->pictureFile->extension, 
                        ['quality' => 70]);
        unlink('../files/upload/' . $this->pictureFile->baseName . '.'  . $this->pictureFile->extension);
    }
