Graphics: Image Verification
Julio Romano (contact me)
This class can be use to generate CAPTCHA validation images and verify the text written on them.
The class can generate an image with a random text. The text is rendered using a random font, a random inclination angle and has several lines over the text to make it fuzzy. The image is generated in the JPEG format.
The verification text is stored in a session variable so the class can verify whether the validation text the user entered matches the text displayed in the image.
