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,
       grabVideoFrames, 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
               parameter.

       -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
               another.  Default 1000000, which is one second.

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

       -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.
