Thumbnail generator with caching and watermark support.

1. Load the core class in the PHP file that will output the thumbnail:

   require_once('path_to/ThumbGen.class.php');

2. Create a new ThumbGen object:

   $thumbGen = new ThumbGen();

3. Setup the ThumbGen object as needed and generate the thumbnail:

   $thumbGen->getThumbnail('path_to/image.jpg');

4. Output the thumbnail image:

   $thumbGen->outputThumbnail();

Note: If you want to use caching, make sure the cache folder is writable.

1. In order to use the Watermark features you need to also load the Watermark plugin class:

   require_once('path_to/ThumbGen.class.php'); require_once('path_to/Watermark.class.php');

2. Create a Watermark object:

   $tgWatermark = new \ThumbGen\Watermark();

3. Setup the Watermark options:

   $tgWatermark->setWatermark('path_to/watermark.png');

4. Apply the watermark to the thumbnail:

   $tgWatermark->addWatermark($thumbGen);

5. Update the thumbnail with the watermarked version:

   $thumbGen->updateThumbnailData($tgWatermark->getThumbnailData());

6. And finally, generate the thumbnail:

   $thumbGen->outputThumbnail();

Note: The watermark image must be PNG.

Please see the examples for actual code.

• Added the magic method __get() in the ThumbGen class so properties can be easily retrieved from a plugin. Only specific properties are available.

• Changed the plugin arhitecture so the plugins are now separate objects that extend the abstract Plugin object.

• Fixed the caching to use the set duration instead of being infinite (util the source image was modified);

• Watermark: the setWatermark repetition doesn't need to be an array and include the padding when it's set to 'no-repeat'.

• Initial version
