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.
