/** @brief Draws a simple or thick elliptic arc or fills an ellipse sector.
The function cv::ellipse with less parameters draws an ellipse outline, a filled ellipse, an elliptic
arc, or a filled ellipse sector. A piecewise-linear curve is used to approximate the elliptic arc
arc, or a filled ellipse sector. The drawing code uses general parametric form.
A piecewise-linear curve is used to approximate the elliptic arc
boundary. If you need more control of the ellipse rendering, you can retrieve the curve using
ellipse2Poly and then render it with polylines or fill it with fillPoly . If you use the first
variant of the function and want to draw the whole ellipse, not an arc, pass startAngle=0 and
endAngle=360 . The figure below explains the meaning of the parameters.
cv::ellipse2Poly and then render it with polylines or fill it with cv::fillPoly. If you use the first
variant of the function and want to draw the whole ellipse, not an arc, pass `startAngle=0` and
`endAngle=360`. The figure below explains the meaning of the parameters to draw the blue arc.
