NAME

       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]

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-demo(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.

       -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.
