| Detailed description | ||
| This class can be used to display CAPTCHA images and validate forms that use them to verify whether the user is really a human or a robot. It can generate an image with a random text taken from a text file. The text is rendered using TrueType fonts over a background of random faded text letters and background images. The generated image is stored on a file in GIF, JPEG or PNG formats. The validation word is stored in a session variable for posterior verification. This dimensions, the fonts, and the background images are configurable. |
