// This code example demonstrates how to draw a closed curve, arc, and circle.
// Create a Bitmap
Bitmap bitmap = new Bitmap(1000, 800);

// Initialize Graphics from Bitmap
Graphics graphics = Graphics.fromImage(bitmap);

// Define a Pen to draw
Pen penBlue = new Pen(Color.getBlue(), 4);

// Draw a curve
graphics.drawClosedCurve(penBlue, new Point[] { new Point(10, 700), new Point(250, 500), new Point(500, 10), new Point(750, 500), new Point(990, 700) });

// Draw an Arc
Pen penRed = new Pen(Color.getRed(), 2);
graphics.drawArc(penRed, 0, 0, 700, 700, 0, 180);

// Draw an Ellipse
Pen penGreen = new Pen(Color.getGreen(), 2);
graphics.drawEllipse(penGreen, 10, 10, 500, 500);

// Save the bitmap as PNG
bitmap.save("D:\\Files\\Curves.png");
