NAME
       slidescreen - permute the screen	image like an 8-puzzle

SYNOPSIS
       slidescreen  [-display host:display.screen] [-background	color] [-grid-
       size pixels] [-ibw pixels] [-increment pixels] [-delay usecs]  [-delay2
       usecs]  [-duration  secs] [-window] [-root] [-install] [-visual visual]
       [-fps]

DESCRIPTION
       The slidescreen program takes an	image, divides it into a grid, deletes
       a  random  square  of  that  grid,  and then randomly slides one	of the
       neighbors of this "hole"	into the hole (and repeat.)

       The image that it manipulates will be grabbed from the portion  of  the
       screen underlying the window, or	from the system's video	input, or from
       a random	file on	disk, as indicated by the grabDesktopImages, grabVide-
       oFrames,	 and  chooseRandomImages  options in the ~/.xscreensaver file;
       see xscreensaver-demo(1)	for more details.

OPTIONS
       slidescreen accepts the following options:

       -window Draw on a newly-created window.	This is	the default.

       -root   Draw on the root	window.

       -install
	       Install a private colormap for the window.

       -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.

       -grid-size pixels
	       The size	of the grid cells.  Default 70 pixels.

       -ibw pixels
	       The size	of the "gutter"	between	grid cells.  Default 4 pixel.

       -increment pixels
	       How many	pixels by which	a piece	should be moved	 when  sliding
	       to a new	location.  Default 10 pixels.

       -delay microseconds
	       How  much  of a delay should be introduced between steps	of the
	       animation of the	motion of each segment.	 Default 50000,	 which
	       is 0.05 seconds.	 This is closely related to the	-increment pa-
	       rameter.

       -delay2 microseconds
	       How much	of a delay should be introduced	between	the end	of the
	       motion  of  one	segment	and the	beginning of the motion	of an-
	       other.  Default 1000000,	which is one second.

       -duration seconds
	       How long	to run before loading a	new image.  Default  120  sec-
	       onds.

       -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.
