boxfit(6) XScreenSaver manual boxfit(6) NAME boxfit - fills space with a gradient of growing boxes or circles. 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 hor- izontal 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 ani- mation. 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. De- fault 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 gradi- ent. 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 grabDesktopIm- ages, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-settings(1) for more de- tails. --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 re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. SEE ALSO X(1), xscreensaver(1) xscreensaver-settings(1), xscreensaver-getimage(6) COPYRIGHT Copyright (C) 2005 by Jamie Zawinski.
