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);}}
}
