SYNOPSIS

       boxfit  [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id
       number] [--delay usecs] [--count  int]  [--growby  int]  [--spacing  int]  [--border  int]
       [--circles | --squares | --random] [--grab] [--peek] [--fps]

DESCRIPTION

       Packs  the  screen  with  growing  boxes  or circles, colored according to a horizontal or
       vertical gradient.  The objects grow until they touch, then  stop.   When  the  screen  is
       full, they shrink away and the process restarts.

OPTIONS

       --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.

       --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.

       --delay microseconds
               How much of a delay should be introduced between steps of the animation.   Default
               20000, or about 0.02 seconds.

       --count int
               How  many boxes or circles to animate simultaneously; default 50.  Smaller numbers
               yield larger boxes/circles.

       --growby int
               How many pixels the objects should grow by, each frame.  Default 1.

       --spacing int
               How many pixels of space should be left between the objects.  Default 1.

       --border int
               Thickness of the colored border around each object.  Default 1.

       --circles | --squares | --random
               Draw circles, squares, or choose randomly (the default).

       --grab  Normally it colors the boxes with a horizontal or vertical gradient.  If --grab is
               specified,  it  will instead load a random image, and color the boxes according to
               the colors in that  image.   As  the  picture  fills  in,  some  features  of  the
               underlying image may become recognisable.

               When  grabbing  images,  the  image 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.

       --peek  This  option  says to briefly show you the underlying image before beginning.  The
               default is not to show the unadulterated image at all.  (This only has  an  effect
               when --grab is used.)

       --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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
