Вот программный код этого класса:

using System;

using System.Drawing;

namespace Shapes

{

/// <summary>

/// Класс Ellipse - потомок класса Figure.

/// </summary>

public class Ellipse: Figure

{

int axisA,axisB;

Rectangle rect;

public Ellipse(int A, int B, int x, int y ): base(x,y)

{

axisA = A; axisB = B;

rect =Init();

}

public override void Show(Graphics g, Pen pen, Brush brush)

{

rect = Init();

g.DrawEllipse(pen,rect);

g.FillEllipse(brush, rect);

}

public override Rectangle Region_Capture()

{

rect = Init();

return rect;

}

Rectangle Init()

{

int a =Convert.ToInt32(axisA*scale);

int b =Convert.ToInt32(axisB*scale);

int leftupX = center.X - a;

int leftupY = center.Y - b;

return( new Rectangle(leftupX,leftupY,2*a,2*b));

}

}

}
