NAME

       decayscreen - make a screen meltdown.

SYNOPSIS

       decayscreen  [-display  host:display.screen]  [-window] [-root] [-mono]
       [-install] [-visual visual] [-delay usecs] [-mode mode]

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.

       -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).

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.
