Because it simple

Reason I add new extension:

It simple and very easy to use
Lightweight and your page will load faster

Most of time, I just need to resize image.

Error persists

Can you fix this issue

Property "CWebApplication.simple_image" is not defined.

I copied CSimpleImage.php and simple_image.php to extensions folder

Here is my configuration

'components' => array(

    'file' => array(
        'class' => 'application.extensions.file.CFile',
    ),
  
    'simpleImage' => array(
        'class' => 'application.extensions.CSimpleImage',
    ),
  ....
public function actionTest() {  
    $file = "images/logo.jpg";  
    $img = Yii::app()->simple_image->load($file);  
  //  $img = Yii::app()->simpleImage->load($file); i have tried this line also  
    $img->resizeToWidth(128);  
    $img->save("newLogo.jpg"); 
}

Fixed

I am sorry when I gave the wrong class name.
You just replaced this line:

$img = Yii::app()->simple_image->load($file);

To this:

$img = Yii::app()->simpleImage->load($file);

This would make the extension run properly.

Property "CWebApplication.simpleImage" is not defined.

I changed every simple_image to simpleImage also in trying to overcome this.

view:

$file=$this->createUrl('displaySavedImage',array('id'=>$model->primaryKey));
	$img = Yii::app()->simpleImage->load($file);
	$img->resizeToWidth(128);
	$img->output();

Is this because of my folder structure?

$homePath      = dirname(__FILE__) . '/../..';
$protectedPath = _joinpath($homePath, 'protected');
$webrootPath   = _joinpath($homePath, 'webroot');
$runtimePath   = _joinpath($homePath, 'runtime');

if so what do I need to change in the extension to make it work for me?

simple image

The name simpleImage is defined in protected/config/main.php

'simpleImage'=>array(
                    'class' => 'application.extensions.CSimpleImage',
                ),

if you can the file in simple_image.php to simpleImage.php. You need to change CSimpleImage.php to reflex that change

Still not working.

Hi DavidTran, thanks for the quick response. I have changed every instance of the name to simpleImage and it does not work. This is after I tried your code as provided.

This is is consistent no matter what I try to change to get things to work.
Property "CWebApplication.simpleImage" is not defined.

I appreciate you putting this together and it is something I could really use so it would be nice to understand how to get it working.

     'class' => 'ext.resizeImage.CSimpleImage'
)

$file = "images/logo.jpg";
$img = Yii::app()->simpleImage->load($file);
$img->resizeToWidth(128);

Cropping

I appreciate this may go beyond of what the extension originally wanted to achieve, but I had to crop a few images and instead of adding yet another extension, I added the following method to this one:

function crop($startX, $startY, $width , $height) {
      $new_image = imagecreatetruecolor($width, $height);
      imagecopyresampled($new_image, $this->image, 0, 0, $startX, $startY, $width, $height, $width, $height);
      $this->image = $new_image;   
   }

Might come in handy for someone, I presume.

Cheers,

Cass

Save Method Improvement

I've changed simple_image::save() as follows:

function save($filename, $image_type=false, $compression=75, $permissions=null) {
  $image_type = $image_type ? $image_type : $this->image_type;

This way saving a non-jpg image will not require adding image type parameter when calling save().

Edit: Adding at the end of the methods:

return $this;

one may do calls like

Yii::app()->simpleImage->load($imgPath)->crop($conf['w'],$conf['h'])->save($imgPath);

Property "CWebApplication.simpleImage" is not defined

If you get this error make sure that you've placed

'simpleImage'=>array(
                    'class' => 'application.extensions.CSimpleImage',
                ),

In the correct place and not in the middle of another array ( ),

Great extension, thanks!

Why new extension?

@Maciej:

I already tried 'image' extension which exported from Kohana, but it have problem with multiple file upload (CUploadedFile). I always get this error if I upload 2 images or more

Fatal error: Cannot redeclare class Image_GD_Driver in /home/user/public_html/protected/extensions/image/drivers/GD.php on line 380

I tried to unset every variable for each loop, but still got these error.

But this extension (simpleimage) work perfectly for CUploadedFile.
