New Symfony Plugin "jsThumbnailPlugin" for on-the-fly Thumbnails Creation

Today I have released my first plugin for the Symfony-Framework. The jsThumbnailPlugin creates Thumbnails on the fly using the GD library. It uses the Symfony cache system to cache the thumbnails.



The plugin consists of a action and a helper. It creates a thumbnail of a image in the given size and stores it in cache for the next calls, until the image changes. You can download it from http://www.symfony-project.org/plugins/jsThumbnailPlugin

The use is very simple:
1. Install it:
$ symfony plugin-install http://plugins.symfony-project.com/jsThumbnailPlugin


2. Enable the module in the setting.yml file of your application:
all:
.settings:
enabled_modules: [ default, jsThumbnail ]


3. Now you can view the thumbnail simply by open a link like this:
http://www.yourhost.com/yourapp.php/jsThumbnail/thumbnail?img=uploads/pictures/image.jpg&maxx=100&maxy=80


4. The plugin has a helper that creates a image-tag for a thumbnail. Include the helper in your template-file:



5. Call the Helper. The helper needs some params: the imagepath on server, maximum-width and maximum-height. The last parameter are additional HTML compliant tag parameters:
 'border: 1px solid #ff0000')) ?>


6. The Plugin automatically checks if the Original image was modificated.

7. To delete the cached thumbnails call:
$ symfony cc
