SYNOPSIS

slidescreen [--display host:display.screen] [--background color]
[--grid-size pixels] [--ibw pixels] [--increment pixels] [--delay
usecs] [--delay2 usecs] [--duration secs] [--window] [--root]
[--window-id number] [--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-settings(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.

--window-id number
Draw on the specified 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.

XSCREENSAVER_WINDOW
The window ID to use with --root.
