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] [-window] [-root] [-install] [-visual visual]


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 1 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.

       -delay 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.


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.
