NAME

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

SYNOPSIS

       ifs  [-display  host:display.screen]  [-visual visual] [-window] [-root] [-no-db] [-delay number] [-detail number] [-colors number] [-func-
       tions 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.

       -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

       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.
