NAME

decayscreen - make a screen meltdown.

SYNOPSIS

decayscreen [--display host:display.screen] [--window] [--root]
[--window-id number] [--mono] [--install] [--visual visual] [--delay
usecs] [--duration secs] [--mode mode] [--fps]

DESCRIPTION

The decayscreen program creates a melting effect by randomly shifting
rectangles around the screen.

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

decayscreen 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.

--mono If on a color display, pretend we're on a monochrome display.

--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.

--delay microseconds
Slow it down.

--duration seconds

seconds.

--mode mode

values are random (meaning pick one), up, left, right, down,
upleft, downleft, upright, downright, shuffle (meaning prefer
no particular direction), in (meaning move things toward the
center), out (meaning move things away from the center), melt
(meaning melt straight downward), stretch (meaning stretch
the screen downward), and fuzz (meaning go blurry instead of
melty).

--fps Display the current frame rate and CPU load.
