SatView provides a utility for looping through opaque images (satellite images or filled contours) underneath the current map and overlays. The easiest way to activate the looping is to click the left button on the Utility menu. Since looping is the default action for this menu button, it starts immediately. When it begins, a slider appears next to it. Use this slider to control the looping speed.
It is also possible to control the direction (forward or backward) of the looping, as well as whether SatView should loop continuously, or stop after a single cycle. The Looping sub-menu of the Utility button has submenus of its own to control this behavior.
