Gray scale edge checker: Position adjustment
Gray edge checkers are used as the base checkers, calculating adjustments ∆X and
∆Y from the results of vertical and horizontal scanning checkers.
Shapes available are lines and planes, with a mixture of the two being possible.
There is no need to set both the horizontal and vertical base checkers if not required.
If only one is set, the adjustment in that direction will be calculated.
If both checkers are set, the order of priority can be specified.
Edge detection is performed in Front detection position mode.
The reference point is the intersection between vertical and horizontal lines passing
through the coordinate obtained by the horizontal checker and the coordinate obtained
by the vertical checker.
The distance between the reference point and the detection point is the amount of
adjustment.
