splitflap(6) XScreenSaver manual splitflap(6) NAME splitflap - a simulation of a split-flap electromechanical display. SYNOPSIS splitflap [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--delay microseconds] [--speed float] [--width columns] [--height rows] [--mode text | clock12 | clock24] [--no- wander] [--spin axes] [--no-spin] [--front] [--no-front] [--wireframe] [--fps] DESCRIPTION Simulates a split-flap display, an old style of electromechanical sign as seen in airports and train stations, and commonly used in alarm clocks in the 1960s and 1970s. 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: 20000 (0.02 seconds). --speed number Animation speed. 2.0 means twice as fast, 0.5 means half as fast. --width number Columns of the display. Default: 22. --height number Rows of the display. Default: 8. --mode clock12 Display a 12-hour clock. --mode clock24 Display a 24-hour clock. --front | --no-front When spinning, never spin all the way around or upside down: always face mostly forward so that the text is easily readable. This is the default. --no-front Allow spins to go all the way around or upside down. --wander | --no-wander Whether the object should wander around the screen. --spin Which axes around which the text should spin. The default is "XYZ", meaning rotate it freely in space. "--spin Z" would rotate the text in the plane of the screen while not rotating it into or out of the screen; etc. --wireframe | --no-wireframe Render in wireframe instead of solid. --fps | --no-fps Whether to show a frames-per-second display at the bottom of the screen. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. SEE ALSO X(1), xscreensaver(1) COPYRIGHT Copyright (C) 2015 by Jamie Zawinski.
