NAME

       boxfit - fills space with a gradient of growing boxes or circles.

SYNOPSIS

       boxfit  [-display  host:display.screen]  [-visual  visual]  [-window] [-root] [-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.

       -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-demo(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.
