    NAME
         jigsaw - permute the screen image like a jigsaw puzzle
    
    SYNOPSIS
         jigsaw [-display  host:display.screen]  [-background  color]
         [-delay usecs] [-window] [-root] [-install] [-visual visual]
    
    DESCRIPTION
         The jigsaw program takes an image of the screen,  carves  it
         up into a jigsaw puzzle, shuffles it, and then solves it.
    
    OPTIONS
         jigsaw accepts the following options:
    
         -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.
    
         -delay microseconds
                 How long to wait between shuffling  pieces;  default
                 700000, or 0.7 seconds.
    
    RESOURCES
         On some systems (currently, only SGIs),  this  program  can,
         instead  of  grabbing a desktop image, grab a frame of video
         from an external camera and manipulate  that  instead.   The
         following resources control that.
    
         grabVideoProbability (Float)
                 What portion of the time to grab video rather than a
                 screen image, between 0.0 and 1.0.  Defaults to 0.5,
                 or half the time.
    
         videoDevice (Integer)
                 The number of the  default  video  input  device  to
                 check  first.   If  unspecified,  the default camera
                 (from videopanel(1)) will be checked  first.   After
                 that,  all  other available video input devices will
                 be checked in order.
    
                 The first one which produces a non-black image  will
                 be  used.   If all images are black, the others will
                 be re-checked a  few  times  before  giving  up  and
                 falling back to simply grabbing a desktop image (but
                 note that this takes a few seconds, so if you  don't
                 actually  have  any  video  sources  hooked  up, you
                 should consider turning off video grabbing  by  set-
                 ting grabVideoProbability to 0.0.)
    
         videoGain (Float)
                 The amount by which to brighten the  grabbed  image.
                 This defaults to 2.2.
    
    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.
