Fig. 2.1
As in the figure above, if calculated with relative coordinates, the coordinates of the entire graphics will be:
1. A is the origin, and the coordinates are X0, Y0;
2. B relative to A: X50, Y50;
3. C relative to B: X50, Y50;
4. D relative to C: Y-50;
5. D relative to B: X-50;
2.2 Absolute coordinates
In the coordinates system, if the position of current coordinates is calculated from origin coordinates’ position, it
is called as absolute coordinates; as in Fig. 2.1 the coordinates of entire graphics calculated absolute coordinates
will be:
1.
A is the origin, and the coordinates are X0, Y0;
2.
B relative to A: X50, Y50;
3.
C relative to A: X100, Y100;
4.
D relative to A: X100, Y50;
5.
D relative to B: X50, Y50;
