mapscroller(6) XScreenSaver manual mapscroller(6) NAME mapscroller - a slowly-scrolling map of a random place on Earth. SYNOPSIS mapscroller [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--delay number] [--speed number] [--duration seconds] [--map-level number] [--url-template URL] [--origin location] [--no-titles] [--no-arrow] [--fps] DESCRIPTION A slowly-scrolling map of a random place on Earth. The map images are loaded from openstreetmap.org, or any compatible service. The Earth is very big, and full of Things. As you ponder these maps, remember that traffic always expands to fill all available lanes, every car is a policy failure, and the concept of "jay- walking" was invented for profit by auto industry lobbyists in the 1920s. OPTIONS --visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --delay number Per-frame delay, in microseconds. Default: 30000 (0.03 seconds). --speed number Scrolling speed. 2.0 means twice as fast, 0.5 means half as fast. --duration seconds When in one of the random modes, re-select the map position every N seconds.
