How to resize an image in YII?

When I try to load and resize an image:

$image = Yii::app()->image->load($path);
$image->resize(400, 100);

I get this error

Property "CWebApplication.image" is not defined.

I've tried in the config file to put this:

'image'=>array(
          'class'=>'application.extensions.image.CImageComponent',
            // GD or ImageMagick
            'driver'=>'GD',
            // ImageMagick setup path
            'params'=>array('directory'=>'/opt/local/bin'),
        ),

anyway I'am getting an error, how to resize an image in yii any ideas?, is there any native class to work with images?

You must add the ImageMagick setup path in config file "main.php"

here the sample for windows

'image'=>array(
        'class'=>'application.extensions.image.CImageComponent',
        // GD or ImageMagick
        'driver'=>'GD',
        // ImageMagick setup path
        'params'=>array('directory'=>'D:/Program Files/ImageMagick-6.4.8-Q16'),
    ),

for linux

'image'=>array(
        'class'=>'application.extensions.image.CImageComponent',
        // GD or ImageMagick
        'driver'=>'GD',
        // ImageMagick setup path
        'params' => array('directory' => '/usr/bin'),
    ),

and then you can resize the image like this

$image = Yii::app()->image->load('images/test.jpg');
$image->resize(400, 100)->rotate(-45)->quality(75)->sharpen(20);
$image->save(); // or $image->save('images/small.jpg');

use the flowing extension image extension

I think its too late response. But it will help others. I have a got into a similar problem. I fixed it by the following method.

From your question i understand that you are using an extension called "image" in yii. In the page of the extension itself they given a description called "usage". I followed that to fix.

I have added some note in the usage documentation and added below which may lead to that issue.

The following code is the component registration in the config file(config/main.php):

'import'=>array(
    ...
    'application.helpers.*',
    ...
),

May be you may done mistake in this following part. you need to register the "image" component inside the components section in the config/main.php file. 

'components'=>array(
       'image'=>array(
          'class'=>'application.extensions.image.CImageComponent',
            // GD or ImageMagick
            'driver'=>'GD',
            // ImageMagick setup path
            'params'=>array('directory'=>'/opt/local/bin'),
        ),...
)

See the following code example:

$image = Yii::app()->image->load('images/test.jpg');
$image->resize(400, 100)->rotate(-45)->quality(75)->sharpen(20);
$image->save(); // or $image->save('images/small.jpg');//You missed this line

(or) you can also use like below without registering the image component in the config/main.php file.

Yii::import('application.extensions.image.Image');
$image = new Image('images/test.jpg');
$image->resize(400, 100)->rotate(-45)->quality(75)->sharpen(20);
$image->render();

When configuring application components put them in components config section, it seems that you put image component in wrong place.

This should work:

return [
    // ....
    'components' => [
        'image' => [
            'class' => 'application.extensions.image.CImageComponent',
            // GD or ImageMagick
            'driver' => 'GD',
            // ImageMagick setup path
            'params' => ['directory' => '/opt/local/bin'],
        ],
    ]
];
