        slidescreen - permute the screen image like an 8-puzzle


        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]


        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.


        slidescreen accepts the following options:
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
                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
        -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
        -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 sec-
        -fps    Display the current frame rate and CPU load.


        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.
