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'', ''grabVideoFrames'', and ''chooseRandomImages'' options in the ''~/.xscreensaver'' file; see xscreensaver-demo(1) for more details. !!OPTIONS ''zoom'' accepts the following options: __-window__ Draw on a newly-created window.
