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.
