| Detailed description | ||
| This class can be used to generate images for CAPTCHA validation. It can generate an image with a random validation text over a noise background. The generated image is served as the current script output in JPEG or PNG format. The class returns the rendered text string for later validation. It uses a configurable TrueType font to render the text. The text color, font size and rotation are also configurable parameters. |
