       jigsaw - permute an image like a jigsaw puzzle

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.
