NAME

        decayscreen - make a screen meltdown.
 

SYNOPSIS

        decayscreen  [-display  host:display.screen]  [-window] [-root] [-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, grabVide-
        oFrames,  and  chooseRandomImages  options in the ~/.xscreensaver file;
        see xscreensaver-demo(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.
 
        -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  sec-
                onds.
 
        -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.
