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.
