NAME
rotzoomer - animated rotations and scalings of portions of the screen

SYNOPSIS
rotzoomer [-display host:display.screen] [-move | -no-move] [-delay usecs] [-n count] [-shm | -no-shm] [-window] [-root] [-install] [-visual visual]

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-demo(1) for more details.

OPTIONS
rotzoomer accepts the following options:

-window
    Draw on a newly-created window. This is the default.

-root
    Draw on the root window.

-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
    How much of a delay should be introduced between steps of the animation. Default 10000, or about 1/100th second.

-move
    Make the rectangles should wander around the screen.

-no-move
    Make the rectangles be stationary. This is the default.

-n count
    How many rectangles to animate simultaneously. Default 2.

-no-shm
    Disable use of the SHM extension, even if it appears to be available.

ENVIRONMENT

    to get the default host and display number.
