6.7.4.4 Used Measuring Algoritms
The RECTANGLE algorithm
▼ How does it work
1. Find the rough centre and angle of the reflecting areas.
2. Measure the North-South vertical size and centre.
3. Measure the North and South horizontal size, and update the position of the
horizontal centre of the component with these measured values.
4. Check the component’s vertical and horizontal size, and place rulers. The rulers
will be placed on the following positions: The center of the component found by
step 2 and 3, incremented by the vertical size - or horizontal size, depending on
the component’s orientation - divided by two, and decremented by the ruler
offset.
5. Execute a vertical or a horizontal optimization, depending on whether the
component is a vertical or a horizontal rectangle, see below.
▼
Vertical optimization
The most Northern and the most Southern position will be measured at which hori-
zontal rulers will be drawn. Now the optimized centre and angle are calculated.
▼
Horizontal optimization
The most Eastern and the most Western position will be measured at which vertical
rulers will be drawn. Now the optimized centre and angle are calculated.
