  Detailed description  
This class generates an image with random text to verify that a form was submitted by a real human being.

It adds some visual elements that are meant to confuse OCR (Optical Character Recognition) software, thus making it very difficult for robot scripts to determine the actual text that is displayed in the generated image.

Requires GD library compiled with PHP.
