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,
       grabVideoFrames, 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 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.
