If you choose Edit from the Image Registration dialog box, MapInfo Pro displays the Edit Control Point dialog box, which has the following options:
Label
Enter an optional label in this field.
Map X, Map Y
Enter the x- and y-coordinate values, such as longitude and latitude, in these fields.
If you are entering coordinates in degrees (the default), any location west of the Prime Meridian has a negative x-coordinate, and any point south of the Equator has a negative y-coordinate. Thus, 73 degrees West is represented by the X value -73.
Image X, Image Y
These fields represent the position of the control point, in pixels, on the raster image. An Image X value of zero represents the left edge of the image, and an Image Y value of zero represents the top edge of the image.
