Description Author

This class is meant to generate CAPTCHA (Completely Automated Public Turing to tell Computers from Humans Apart) images to test whether the user accessing a site is a real human or an automatic script.

The class generate an image with a random key text string printed on it mixed with some noise made of random text characters or line grid.

The image is meant to be used in a form so the user reads the key text in the image and must enter it to prove that is a real human.

The form also passes an hidden field that contains a public key that is used when the form is submitted to the server to verify whether the key text on the image matches what the user entered.
