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, grabVide-
        oFrames,  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.
