Overview
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 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.
Environment
-
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.
