zoom(6) XScreenSaver manual zoom(6) NAME zoom - wander around magnified desktop SYNOPSIS zoom [--display host:display.screen] [--foreground color] [--background color] [--window] [--root] [--window-id number][--mono] [--install] [--vi- sual visual] [--delay usecs] [--duration secs] [--lenses] [--pixwidth pix- els] [--pixheight pixels] [--pixspacex pixels] [--pixspacey pixels] [--lensoffsetx pixels] [--lensoffsety pixels] [--fps] DESCRIPTION The zoom program takes an image, magnifies it, and scrolls around it, fat- bits-style. The image that it manipulates 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, grabVide- oFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-settings(1) for more details. OPTIONS zoom accepts the following options: --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. --mono If on a color display, pretend we're on a monochrome display. --install Install a private colormap for the window. --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. --delay microseconds Slow it down. --duration seconds How long to run before loading a new image. Default 120 seconds. --lenses Instead of doing magnification we just copy an offset region from the original image. If lensoffsetx < pixwidth (and similarly for Y) then consecutive regions will overlap, giving the effect of looking through an array of lenses. --pixwidth pixels Width of the magnified pixels. --pixheight pixels Height of the magnified pixels. --pixspacex pixels Amount of black space between magnified pixels (X direction). --pixspacey pixels Amount of black space between magnified pixels (Y direction). --lensoffsetx pixels Distance in X direction between consecutive copied regions (only effective when -lenses used). --lensoffsety pixels Distance in Y direction between consecutive copied regions (only effective when -lenses used). 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) 2000 by James Macnicol.
