rotzoomer - animated rotations and scalings of portions of the screen

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

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.

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.

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
