This application allows you to capture the entire screen, the active window or a selected region. You can set the delay that elapses before the screenshot is taken and the action that will be done with the screenshot: save it to a PNG file, copy it to the clipboard, or open it using another application.
A plugin for the Xfce panel is also available.
