Thumb create in Yii2 gives an error - php

Question

I want to create a thumb but am getting this error:
PHP Fatal Error – yii\base\ErrorException
Class 'Imagine\Image\ManipulatorInterface' not found
I don't know from where i can get this? I used yii2-imagine but didn't find any ManipulatorInterface class.
controller file:
<?php
namespace backend\controllers;
use Yii;
use app\models\Employee;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\AccessControl;
use yii\filters\VerbFilter;
use yii\web\UploadedFile;
use yii\imagine\Image; // this is where i used Image class
public function actionCreate()
{
$model = new Employee();
$model->added_date_time = date('Y-m-d H:i:s');
if($model->load(Yii::$app->request->post())) {
$model->file = UploadedFile::getInstance($model,'avatar');
if(!empty($model->file)) {
$imageName = Yii::$app->security->generateRandomString();
$model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension);
$model->avatar = $imageName.'.'.$model->file->extension;
$file = 'uploads/'.$imageName.'.'.$model->file->extension;
Image::thumbnail($file, 200, 200)->save('uploads/thumb/', ['quality' => 80]);
}
if($model->save()){
$this->redirect(\Yii::$app->urlManager->createUrl('employee'));
}
}
else {
return $this->render('create', [
'model' => $model
]);
}
}
?>
Image class file is in \vendor\yiisoft\yii2\imagine folder and ManipulatorInterface is in \vendor\yiisoft\yii2\imagine\Imagefolder
Image.php
<?php
namespace yii\Imagine;
class Image extends BaseImage
{
}
?>
BaseImage.php
<?php
namespace yii\imagine;
use Yii;
use imagine\Image\Box;
use imagine\Image\Color;
use imagine\Image\ImageInterface;
use imagine\Image\ImagineInterface;
use imagine\Image\ManipulatorInterface;
use imagine\Image\Point;
use yii\base\InvalidConfigException;
use yii\base\InvalidParamException;
use yii\helpers\ArrayHelper;
class BaseImage
{
public static function thumbnail($filename, $width, $height, $mode = 'outbound')
{
$box = new Box($width, $height);
$img = static::getImagine()->open(Yii::getAlias($filename));
if (($img->getSize()->getWidth() <= $box->getWidth() && $img->getSize()->getHeight() <= $box->getHeight()) || (!$box->getWidth() && !$box->getHeight())) {
return $img->copy();
}
$img = $img->thumbnail($box, $mode);
// create empty image to preserve aspect ratio of thumbnail
$thumb = static::getImagine()->create($box, new Color('FFF', 100));
// calculate points
$size = $img->getSize();
$startX = 0;
$startY = 0;
if ($size->getWidth() < $width) {
$startX = ceil($width - $size->getWidth()) / 2;
}
if ($size->getHeight() < $height) {
$startY = ceil($height - $size->getHeight()) / 2;
}
$thumb->paste($img, new Point($startX, $startY));
return $thumb;
}
?>

I have the same problem. I try 'composer global require "fxp/composer-asset-plugin:~1.0.0"' after that I try 'composer.phar require --prefer-dist yiisoft/yii2-imagine' again and it's work for me. Hope it helps you too

Answer 2

you can try this:
1) copy imagine to your vendor
`pathA: "vendor/Imagine/Draw...."`
2) add a alias into config.php
'components' => [
],
....
'aliases'=>[
'#Imagine'=>'#vendor/Imagine', //this should correspond to pathA above
],
....
'params' => [
],
3) check vendor/composer/autoload_psr4.php
config it like this
return array(
...
'yii\\imagine\\' => array($vendorDir . '/yiisoft/yii2-imagine'),
...
);
4) copy yii-imagine into yiisoft
pathB:"vendor/yiisoft/yii-imagine"
then you can use it .

I have resolved to set path in extensions.php under the yiisoft folder.
Just follow 2 steps:
Open extensions.php
On the bottom of the file add
'yiisoft/yii2-imagine' =>
array (
'name' => 'yiisoft/yii2-imagine',
'version' => '~2.0.0',
'alias' =>
array (
'#yii/imagine' => $vendorDir . '/yiisoft/yii2-imagine',
'#Imagine/Image' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Image',
'#Imagine/Gd' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gd',
'#Imagine/Draw' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Draw',
'#Imagine/Effects' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Effects',
'#Imagine/Exception' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Exception',
'#Imagine/Filter' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Filter',
'#Imagine/Gmagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gmagick',
'#Imagine/Imagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Imagick',
'#Imagine/resources' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/resources',
),
),
So my extensions.php looks like
<?php
$vendorDir = dirname(__DIR__);
return array (
'yiisoft/yii2-swiftmailer' =>
array (
'name' => 'yiisoft/yii2-swiftmailer',
'version' => '2.0.6.0',
'alias' =>
array (
'#yii/swiftmailer' => $vendorDir . '/yiisoft/yii2-swiftmailer',
),
),
'yiisoft/yii2-bootstrap' =>
array (
'name' => 'yiisoft/yii2-bootstrap',
'version' => '2.0.6.0',
'alias' =>
array (
'#yii/bootstrap' => $vendorDir . '/yiisoft/yii2-bootstrap',
),
),
'yiisoft/yii2-debug' =>
array (
'name' => 'yiisoft/yii2-debug',
'version' => '2.0.6.0',
'alias' =>
array (
'#yii/debug' => $vendorDir . '/yiisoft/yii2-debug',
),
),
'yiisoft/yii2-gii' =>
array (
'name' => 'yiisoft/yii2-gii',
'version' => '2.0.5.0',
'alias' =>
array (
'#yii/gii' => $vendorDir . '/yiisoft/yii2-gii',
),
),
'yiisoft/yii2-faker' =>
array (
'name' => 'yiisoft/yii2-faker',
'version' => '2.0.3.0',
'alias' =>
array (
'#yii/faker' => $vendorDir . '/yiisoft/yii2-faker',
),
),
'yiisoft/yii2-imagine' =>
array (
'name' => 'yiisoft/yii2-imagine',
'version' => '~2.0.0',
'alias' =>
array (
'#yii/imagine' => $vendorDir . '/yiisoft/yii2-imagine',
'#Imagine/Image' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Image',
'#Imagine/Gd' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gd',
'#Imagine/Draw' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Draw',
'#Imagine/Effects' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Effects',
'#Imagine/Exception' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Exception',
'#Imagine/Filter' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Filter',
'#Imagine/Gmagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Gmagick',
'#Imagine/Imagick' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/Imagick',
'#Imagine/resources' => $vendorDir . '/yiisoft/yii2-imagine/Imagine/resources',
),
),
);
