Dayyan's CAPTCHA Image: Generate images for CAPTCHA validation

This package can be used to generate images for CAPTCHA validation.

There is one class that can generate a random text string for validation.

Another class is responsible for rendering the validation text. Each character is rendered in a variable position and rotation angle. The class renders several lines over the text to obfuscate it.

The rendered image is generated in the PNG format and is served as the current script output.
