Code:(GraphicsPath类的使用)

using System;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Windows.Forms;

namespace CsStudy
{
    class Flower : XMarksTheSpot
    {
        public new static void Main()
        {
            Application.Run(new Flower());
        }

        public Flower()
        {
            Text = "花朵";
        }
        protected override void DoPage(System.Drawing.Graphics grph, System.Drawing.Color clr, int cx, int cy)
        {
            grph.DrawBezier(new Pen(Color.Green, 10),
                new Point(0, cy), new Point(0, 3 * cy / 4), new Point(cx / 4, cy / 4), new Point(cx / 2, cy / 2));

            float fScale = Math.Min(cx, cy) / 2000f;
            grph.TranslateTransform(cx / 2, cy / 2);
            grph.ScaleTransform(fScale, fScale);

            GraphicsPath path = new GraphicsPath();

            path.AddBezier(new Point(0, 0), new Point(125, 125), new Point(475, 125), new Point(600, 0));
            path.AddBezier(new Point(600, 0), new Point(475, -125), new Point(125, -125), new Point(0, 0));
            for (int i = 0; i < 8; i++)
            {
                grph.FillPath(Brushes.Red, path);
                grph.DrawPath(Pens.Black, path);
                grph.RotateTransform(360 / 8);//旋转出8个花瓣
            }

            Rectangle rect = new Rectangle(-150, -150, 300, 300);
            grph.FillEllipse(Brushes.Yellow, rect);//画花
            grph.DrawEllipse(Pens.Black, rect);
        }
    }
}
