Approximates an elliptic arc with a polyline

pts = cv.ellipse2Poly(center, axes)
[...] = cv.ellipse2Poly(..., 'OptionName', optionValue, ...)

Input

• center Center of the arc [x,y].
• axes Half of the size of the ellipse main axes [a,b]. See cv.ellipse for details.

Output

• pts Output vector of polyline vertices. An Nx2 numeric matrix [x y; ...].

Options

• Angle Rotation angle of the ellipse in degrees. See cv.ellipse for details. default 0.
• StartAngle Starting angle of the elliptic arc in degrees. default 0
• EndAngle Ending angle of the elliptic arc in degrees. default 360
• Delta Angle between the subsequent polyline vertices. It defines the approximation accuracy. default 5.

The function cv.ellipse2Poly computes the vertices of a polyline that approximates the specified elliptic arc. It is used by cv.ellipse. If StartAngle is greater than EndAngle, they are swapped.
