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

How long to run before loading a new image.  Default 120 seconds.

--mode mode

The direction in which the image should tend to slide.  Legal 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.

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.
