SYNOPSISslidescreen [-display host:display.screen] [-background
color] [-grid-size pixels] [-ibw pixels] [-increment pix_
els] [-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 ran
domly 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.

-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 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 pix
els.
-delay microseconds
How much of a delay should be introduced between
steps of the animation of the motion of each seg
ment. Default 50000, which is 0.05 seconds. This
is closely related to the -increment parameter.

the end of the motion of one segment and the
beginning of the motion of another. Default
1000000, which is one second.
