Windowed Screenshot

Image of a web page within a browser as a user will initially see it on their monitor.

Fullpage Screenshot

Chromeless Screenshot

Same as the Fullpage Screenshot with the browser’s chrome (the toolbars, scroll bars, and status bars) removed. This is only the rendered HTML of the page from top to bottom.

Viewport

The viewable area of the web page that can be seen within the browser. This area changes as a web page is scrolled vertically.

Screen Capture

A snapshot image of the browser during the screenshot creating process.

ScreenshotDriver

The software that “drives” the browser during the screenshot process, backed by the Selenium browser automation framework.
