To close a HUD window activate the window by clicking on it with the mouse
or if you have a touchscreen tap on the window then press Alt+F4 on the
keyboard to close.  Closing one HUD window will cause all others to also
be closed.

Switches
────────────────────
-clock        Display a clock tile.

-board        Display a clock tile that allows interaction to draw on the
              screen.  Double clicking the clock will toggle the drawing
              mode on/off.

-b            Same as the -board switch but without the clock.  The draw
              mode is automatically enabled.  Double click the right
              mouse button to exit the board.  Alt+F4 will also close
              the window.  When a board HUD in this mode is closed no
              other HUDs will be affected.

-timer        Displays a countdown timer.  Values expected are seconds 
              or a date and time.  Prefix the time values with an upper
              or lowercase 'X' to automatically close the timer HUD after
              the time has elapsed.  A lowercase 'x' will close only the
              timer HUD and an uppercase 'X' will close all HUDs.
              Syntax:
                To show a countdown for 10 minutes.
                  -timer:600
                To show a countdown till the end of 2022.
                  -timer:2022,12,31,24,0
                To show a countdown for 10 minutes and then close the HUD.
                  -timer:x600

-xaml         Load an XAML file into the HUD.
              Syntax:
              -xaml:"C:\HUD Resources\OverlayGraphics.xaml"

-background   Assign a background using an RGB value or image file.
              Syntax:

                  -background:255,0,0
                RGB HEX values
                  -background:#ff0000
                Image File
                  -background:"C:\HUD Resources\BlueSky.png"

-opacity      Assign the opacity value for the HUD form.
              Syntax:
                -opacity:70

-pointer      Assign a pointer to be displayed, by default the pointer is
              disabled.
              Syntax:
                -pointer
                -pointer:system
                -pointer:255,0,0
                -pointer:#ff0000

-screen       Display the HUD on the specified display.
              Syntax:

 To close the HUD select an active UI element and use the standard Alt+F4
 key combination.  Closing one HUD instance will trigger a call to close
 all HUD instances.

Scripting
────────────────────
Use a Batch file to start multiple instances of the program.  An example
where this would be useful is to start a background instance and an XAML
instance to present graphics from the XAML and hide the current desktop.
In this case other programs can still be shown on screen at the same
time and is useful for video presentations where sharing the screen would
be employed.

Example Batch File
 @echo off
 rem Show an off white background.
 start o7hud.exe -background:#f0f0f0
 rem Show the board UI.
 start o7hud.exe -board
 rem Start the program being used for training or demonstration.
 start excel.exe
