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] [-bor-
der 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. De-
fault 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 gra-
dient. If -grab is specified, it will instead load a random
image, and color the boxes according to the colors in that im-
age. As the picture fills in, some features of the underlying
image may become recognisable.
When grabbing images, the image will be grabbed from the por-
tion 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 op-
tions in the ~/.xscreensaver file; see xscreensaver-demo(1) for
more details.
-peek This option says to briefly show you the underlying image be-
fore 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.
