SYNOPSIS

jigsaw [--display host:display.screen] [--delay usecs] [--speed ratio] [--complexity ratio] [--resolution int] [--thickness float] [--no-wobble] [--fps] [--visual visual] [--window] [--root] [--window-id number]

DESCRIPTION

The jigsaw program loads an image, carves it up into a jigsaw puzzle, shuffles it, and then solves it.

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.

OPTIONS

jigsaw accepts the following options:

--delay microseconds

How long to wait between animation frames; default 20000.

--speed ratio

Less than 1 for slower, greater than 1 for faster. Default 1.

--complexity ratio

Less than 1 for simpler puzzles (fewer pieces), greater than 1 for more complex puzzles (more pieces). Default 1.

--resolution ratio

Smoothness of the edges of the pieces. Less than 1 for rougher pieces (fewer polygons), greater than 1 for more smoother pieces (more polygons). Default 1.

--thickness float

Thickness of the puzzle pieces (relative to their width). Default 0.06.

--no-wobble

Keep the display stationary instead of very slowly wobbling back and forth.

--fps

Display the current frame rate, polygon count, and CPU load.

--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.

--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.

ENVIRONMENT

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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
