The ifs program draws spinning, colliding iterated-function-system images.
--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 functions, 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 functions. This is the historical behavior and may produce neater output 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.
DISPLAY
to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
XSCREENSAVER_WINDOW
The window ID to use with --root.
