Installing and running LiipImagineBundle in symfony 2.1

Question

Here are the steps I followed:

1. Added following in my composer.json:

   "require": {
        "imagine/Imagine": ">=0.2.8",
        "liip/imagine-bundle": "*@dev",
        ....
        }
   

2. Ran following command at command line:

   composer update
   Installing imagine/imagine (v0.4.0)
   Installing liip/imagine-bundle (dev-master f7d5e4d)
   

3. After composer update my directory structure inside vendor folder looks like as below:

4. Then update vendor/composer/autoload_namespaces.php

    'Imagine'   => $vendorDir .'/imagine/Imagine/lib/',
    'Liip\\ImagineBundle'=>$vendorDir . '/liip/imagine-bundle/',
   

5. Registered bundle:

   new Liip\ImagineBundle\LiipImagineBundle(),
   

6. Routing:

   # app/config/routing.yml
   _imagine:
   resource: .
   type:     imagine
   

7. config.yml

     # app/config/config.yml
     liip_imagine:
     filter_sets:
        my_thumb:
           quality: 75
           filters:
              thumbnail: { size: [120, 90], mode: outbound }
   

8. Added to twig template file:

   <img src="{{ asset('bundles/acmedemo/images/1.jpg') | imagine_filter('my_thumb') }}" />
   

9. Open localhost/symfony/web/app_dev.php/demo/hello/test

There was no thumbnail image generation. When viewing the source I found the line:

  <img src="/symfony/web/app_dev.php/media/cache/my_thumb/symfony/web/bundles/acmedemo/images/1.jpg">

What I did I miss? Could somebody help me with this? I am using xampp 1.8 on windows xp with default settings

Answer 1

When I replaced

 <img src="{{ asset('bundles/acmedemo/images/1.jpg') | imagine_filter('my_thumb') }}" />

with

 <img src="{{ 'bundles/acmedemo/images/1.jpg' | imagine_filter('my_thumb') }}" />

I got the thumbnail. I removed the asset() helper of twig and it worked but dont know how it worked.
