<div class="markdown level1 remarks"><p>The arc is drawn by constructing an imaginary circle around the specified center point with the specified radius.
The starting point of the arc is determined by measuring counterclockwise from the x-axis of the circle
by the number of degrees in the start angle. The ending point is similarly located by measuring counterclockwise
from the starting point by the number of degrees in the sweep angle.
If the sweep angle is greater than 360 degrees,the arc is swept multiple times.</p>
