/**
* ImageBatchProcessor class, version 1.0 (for PHP >= 4.3)
* (c) 2008 Vagharshak Tozalakyan <vagh{at}tozalakyan{dot}com>
*
* This class can be used to perform different kind of operations over a group
* of images. It can proportionally resize images (create thumbnails), rotate
* images, convert between different image formats, append textual labels and/or
* small graphic watermarks to images, etc.
*
* Transformation parameters may be applied to all images in a directory or
* separately to each image in a set - the images in source or destination sets
* may be located in the same or different directories.
*
* The class also contains a traversal method which walks through a directory
* and calls a callback function for each item. The method may be used, for
* example, to rename all images (or other files) in a directory using
* predefined naming template (photo01.jpg, photo02.jpg, ...).
