When way symmetry is used to obtain full circle from
When 8- way symmetry is used to obtain a full circle from pixel coordinates generated for the 0 to 45 degree octant, some pixels are set or plotted twice. This phenomenon is sometimes referred to as:
- A.
Interlacing
- B.
Antialiasing
- C.
Overstrike
- D.
Aliasing

Show answer & explanation
Correct answer: C
When using 8-way symmetry to draw a full circle (from a single 0–45° octant), some pixel positions may be calculated more than once due to symmetry. This results in the same pixel being set multiple times, which is known as overstrike.
