NAME¶

rotzoomer - animated rotations and scalings of portions of the screen

SYNOPSIS¶

rotzoomer [--display host:display.screen] [--move | --no-move] [--delay millisecs] [--duration secs] [--n count] [--shm | --no-shm] [--window] [--root] [--window-id number][--install] [--visual visual] [--fps]

DESCRIPTION¶

The rotzoomer program grabs an image, then picks rectangles and draws scaled and rotated animations of that section.

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-settings(1) for more details.

--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 milliseconds

How much of a delay should be introduced between steps of the animation. Default 10, or about 1/100th second.
