(a) File | Open -> 18581a.tif. The Register Image dialog
automatically appears. See the SMS "Register Image" Help topic
for further explanation of registering an image.
(b) To register the image for use as a background display, you need
to know the coordinates of three locations (street, railroad, or
latitude/longitude point on a map, etc.) on the image. Align each
+ symbol with its known reference point on the image. This
alignment defines the three U,V coordinates (local image
coordinates) in the edit fields below the image. Then, enter the
X,Y values, which are the state plane coordinates in meters
corresponding to these reference points, in the edit fields below
the image.

and drag the mouse cursor over the + symbol to form a

For this example, the user can directly input the U, V, X,
and Y to properly register the image.
