NAME
     ifs - draws spinning, colliding iterated-function-system images

SYNOPSIS
     ifs  [--display  host:display.screen] [--visual visual] [--window] [--root]
     [--window-id number] [--no-db] [--delay number] [--detail number] [--colors
     number]  [--functions  number]  [--iterate   |   --recurse]   [--no-rotate]
     [--no-scale] [--no-translate] [--fps]

DESCRIPTION
     The ifs program draws spinning, colliding iterated-function-system images.

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.

     --no-db
	     Disable double-buffering.

     --delay number
	     Per-frame delay, in microseconds.	Default: 20000

     --colors number
	     Number of colours to use. Default: 200

     --detail number
	     In  --iterate  mode,  number of times to randomly iterate the func-
	     tions, in thousands.  In --recurse mode, number of times  to  apply
	     functions (recursion depth) before drawing each point.  Default: 9

     --functions number
	     Number of functions to be iterated. Default: 3

     --iterate
	     Calculate	by iteratively applying the functions in a random order,
	     usually faster than --recurse.  This is the default.

     --recurse
	     Calculate by recursively applying all  combinations  of  the  func-
	     tions.  This is the historical behavior and may produce neater out-
	     put than --iterate.

     --no-rotate
	     Disable the rotation component of the functions.

     --no-scale
	     Disable the scaling component of the functions.

     --no-translate
	     Disable the varying translation component of the functions.

     --no-multi
	     Turn off multi-coloured mode, only one colour is used to colour the
	     whole set.

     --fps   Display the current frame rate and CPU load.

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.
