It oversees file uploads for you. In short, it deals with the uploaded file, and permits you to do whatever you need with the file, particularly in the event that it is a picture, and the same number of times as you need.
It is the perfect class to rapidly incorporate file upload in your site. If the file is a picture, you can change over, resize, crop it from multiple points of view. You can likewise apply channels, include outskirts, content, watermarks, and so on... That is everything you need for an exhibition script for example. Upheld configurations are PNG, JPG, GIF and BMP.
You can likewise utilize the class to chip away at nearby files, which is particularly valuable to image manipulation features. The class additionally backings Flash uploaders.

* When the processing is completed, and the file copied to its new location, the

* This allows you to set new properties, and perform another {@link process} on the same uploaded file
