Version 1.24   6/02/13 Added support for Windows Sensors.  XPort will be used otherwise.  For Windows 7 use GPSDirect.
Version 1.23  11/09/10 Fix for 1.20 auto-adjust ranges. RPM gauge was over sizing.
Version 1.21  3/28/10 Rebuild for compatibility with new XOBD
Version 1.20  1/11/10 Drag objects while config window open. Gauges auto adjust if range limits hit.
Version 1.18 11/ 1/09 XOBD interface improvements.  Fixed many gauge errors.
Version 1.17 10/26/09 Different drawing methods for Windows XP or Vista/7, Windows 7 compatibility for OBD2 interface
Version 1.16 10/16/09 Eliminated flicker, added some OBD-II text and gauges
Version 1.15  8/16/09 Added a few things, switched to GdiPlus for better graphics

Many example skins are included but I'm not an artist. :-)

Move the compass by dragging it.

Task Tray Menu functions:

   Configure - Right-click on the compass or use the menu from the tray icon to open the config window
   Start With Windows - Start when Windows starts
   Always On Top - Always on top, otherwise normal
   Hide Mouse - Hide cursor arrow after 5 seconds of inactivity
   Trip Log - logs each trip to C:\GPSLog\Trip.log as comma delimited text lines (Start-date,Start-time,End-time,Miles)

Config window (left side):

compass graphics editor
The check box enables the selected graphics item.  The 2D slider moves the selected item. (Note: Hovering over an item also selects it, holding down the left button allows for dragging the item)
The 4 value settings depend on the item.  For text, only size is used.  Trails size controls Trails, Sats and Home Target.
Clock: Width = width of hands if no images are available
  Range = max value of gauge (i.e. 150 = 150 MPH)
  Start = Starting value (i.e. 100 for temp sets needle to far left until it reaches 100+)
  Type = 0-3-Round dial, 4/5-Horiz Bar, 6/7-Vert Bar (with and without dial for those who want to draw the gauge in the skin)
                         Angle and Sweep for each gauge is controlled by text item just above it. Ascending/descending is determined by angle of 45-180 deg.
Font name

Font, gauge, trails, etc. color, in decimal as red, green, blue

Other controls:

Stop, log files, and speed slider are for playback of logs.  Just click on a file to start it.  The logs are broadcast to other GPS apps, and the compass clock and all displays will reflect the original data.

Metric - Sets all displays to metric values
Fixed North - Inverse rotation of compass.  Display of Sats, Home Target, Trails and compass will be north up.

The skin combobox shows folders which contain several bmp or png files and are in the same folder as Compass.exe
  Background.png is the background image
  Arrow.png is the compass
  Needle.png is the needle used for all gauges
  Needle2.png is the needle used for all 120 degree gauges (Needle.png is used if not present) (120 and 240 is default if Sweep set to 0)
  Hour.png, Minute.png,  Second.png  is the clock hands
  GaugeH.png and GaugeV.png are for H/V gauges
If Background.bmp is missing it will have a transparent background a little larger than the arrow.
If any other image is missing it will be drawn internally
For bmp use black as the transparent color.
