Draw circle with an EllipsePolygon in ImageSharp

I've just started using ImageSharp to draw images. The documentation on Six Labors web page is clean, but there is no examples to find anywhere about ImageSharp. So I struggle from time to time, all by myself :)

I want to draw a circle with PathBuilder and a given position in x and y as a center point, and a given radius.

I tried to use an EllipsePolygon where you can define x, y, and radius. And then I wanted to draw it in my PathBuilder but PathBuilder only has "AddEllipticalArc" what I can find.

So I have used this function to draw circles instead, like this for example:

pb.AddEllipticalArc(new Point(300, 200), 10, 10, 0, 0, 360);

Is there a better way to draw circles? Or am I supposed to use AddEllipticalArc?

Bonus question: I also have to draw Arcs with only a centerPoint, startPoint and endPoint given to me. But I guess I have to translate these given points and calculate the startAngle and sweepAngle myself. What could be the easiest alternative for this?

You can create a EllipsePolygon object and draw it onto the image:

    var polygon = new EllipsePolygon(new Point(radius, radius), radius);
    image.Mutate(x => x.Draw(Color.White, 5, polygon));
