  • Winform中GDI+绘图(椭圆,直线等)

    用 CreateGraphics 方法创建 Graphics 对象

    Graphics g = this.CreateGraphics();  
    

    画线,下例是一个棋盘:

                //x+=15每一个格子的宽15,y+=15每一个格子的高15  
                for (int x = 10, y = 10, count = 0; count < 15; x += 15, y += 15, count++)  
                {  
                    //220=15*14+10(格子宽*14+期盼最左的线起始x坐标)  
                    g.DrawLine(new Pen(Color.Blue), new Point(10, y), new Point(220, y));  
                    g.DrawLine(new Pen(Color.Blue), new Point(x, 10), new Point(x, 220));  
      
                }
    

    画椭圆:

    g.FillEllipse(Brushes.Black,rtg);
