and them into a line within scan area. Last Line refers to find the set of edge points that have
the closest distance with ending point and them into a line within scan area.
Search Direction
It has two directions, including Top to Bottom, and Left to Right.

It has three modes, including Light to Dark, Dark to Light, and Any. Light to Dark refers to the
transition from the area with a low gray value to the edge of the area with a high gray value.
Dark to Light refers to the transition from the area with a high gray value to the edge of the
