Introduce the extension for Yii 2

Question

With Yii framework 2.0, I want to use the Imagine Extension for Yii 2. After the documentation, I first run the following command line.

php composer.phar require --prefer-dist yiisoft/yii2-imagine "*"

After running the above command line, I could see that the imag package appeared in the vendor directory. In my views of /site/index.php, I included the following code snippet.

use yii\imagine\Image;

// generate a thumbnail image
Image::thumbnail('@webroot/img/test-image.jpg', 120, 120)
->save(Yii::getAlias('@runtime/thumb-test-image.jpg'), ['quality' => 50]);

Below is the result:

 PNG  IHDRxx9d6   pHYs   + IDATx   y eW}  9w o o  ZJ  6  1`޺c  D n     L 8㈞G  c{     r ƀ$   R{UVV  [ {w?g x / ʪJUI ;      =  l       #.\     Bl'    @ ul  IL @)    - "MS< C   +    Z  븫0 R        Ã>   ?    q | ;ߡ n c v      a Dg4'IJ  W `   Įr  a} V ^) վ ~   l6{ |

No image. I do not know what I missed, the image path is correct. Does anyone know how to solve it? thank

, , Yii:: $app- > basePath. "/web/img/testimg.jpg".

siteController.php

Answer 3

This is the right way to generate a thumb and relationship relationship:

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

Image::getImagine()
                ->open($file)
                ->thumbnail(new Box($height, $width))
                ->save($file);
