DESCRIPTION

       The truchet program draws arc and line based Truchet patterns.

OPTIONS

       truchet accepts the following options:

       --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.

       --mono  If on a color display, pretend we're on a monochrome display.

       --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 milliseconds
               How long to wait between drawing each screenful. Default is 1 seconds.

       --min-width integer
               The minimum width in pixels of each square. Default is 40.

       --min-height integer
               The minimum height in pixels of each square. Default is 40.

       --max-width integer
               The maximum width in pixels of each square. Default is 150.

       --max-height integer
               The maximum height in pixels of each square. Default is 150.

       --max-linewidth integer
               The maximum width of the lines used to draw. Default is 25.

       --min-linewidth integer
               The minimum width of the lines used to draw. Default is 2.

       --erase

       --no-erase
               Whether to clear the screen  after  each  screenful  is  drawn.  Default  is  True
               (erase).

       --erase-count integer
               The number of screenfuls to draw before erasing. Default is 25.

       --square

       --not-square
               Whether to force the tiles to be square. Default is True (square).

       --curves

       --no-curves
               Whether to draw the arc based Truchet pattern. Default is True (curves).

       --angles

       --no-angles
               Whether or not to draw the line based Truchet pattern. Default is True (angles)

       --scroll
               Use the scroll mode. Default is False.

       --scroll-overlap
               The amount to scroll from one side to another. Default is 400.

       --anim-delay
               The time to pause between each animation step. Default is 100.

       --anim-step-size
               The amount of steps to skip between each animation step. Default is 3.

       --fps   Display the current frame rate and CPU load.

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.
