3. Algorithm: Special 2 (Component with shape consisting of 2 sec-
tions)
This is useful when the component is divided into 2 sections as shown below.
The center position is an average of center-of-gravity of each section. The tilt is found from the tilt
of the direct line joining the center-of-gravity positions of the 2 sections.

4. Algorithm: Special 3 (Component with shape consisting of 4 sec-
tions)
Find the center-of-gravity positions G1 to G4 for the 4 sections. Find P1 to P8 that connect those
center-of-gravity positions by straight lines. The component center is the intersection (cross point)
of the lines joining the side center found from P1 and P2, and the side center found from P3 and
P4; and the line joining the side center found from P5 and P6 and the side center found from P7
and P8. The component tilt is found from the tilt of 2 lines.

5. Algorithm: Special 4 (Component consisting of multiple sections)
Finds the center of each side and finds the component tilt from the lines joining those side centers.
Algorithm can be used when there are leads on the bottom only, left only, right only, top and
bottom, left and right, top and lower left, top and lower right, upper left and right, lower left and
right, top bottom left and right.
Several methods can be selected to find the component center.
When Option 2 is 0, the center of a circumscribed rectangle is taken as the component center.
When Option 2 is 1, the rectangle center found from lines running from the center of each side is
taken as the component center.
When Option 2 is 2, the average center point of the detected leads is taken as the component
center.
