ifs - draws spinning, colliding iterated-function-system images
ifs [-display host:display.screen] [-visual visual] [-window] [-root]
[-no-db] [-delay number] [-detail number] [-colors number] [-functions
number] [-iterate | -recurse] [-no-rotate] [-no-scale] [-no-translate]
The ifs program draws spinning, colliding iterated-function-system
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-no-db Disable double-buffering.
Per-frame delay, in microseconds. Default: 20000
Number of colours to use. Default: 200
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.
Number of functions to be iterated. Default: 3
Calculate by iteratively applying the functions in a random
order, usually faster than -recurse. This is the default.
Calculate by recursively applying all combinations of the
functions. This is the historical behavior and may produce
neater output than -iterate.
Disable the rotation component of the functions.
Disable the scaling component of the functions.
Disable the varying translation component of the functions.
Turn off multi-coloured mode, only one colour is used to colour
the whole set.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
