只要执行了一个涉及到显示连接线段的操作,就可以设置连接线段的样式。为此,可以使用System.Drawing.Drawing2D命名空间中的LineJoin枚举的值,:Milter(默认值)、Beveled、MilterClipped和Round.
在下面的代码中,我们把Pen对象的LineJoin属性设置为值LineJoin.Bevel,然后用它绘制一个矩形:
1 private void Form1_Paint(object sender, PaintEventArgs e) 2 { 3 Graphics g = e.Graphics; 4 g.SmoothingMode = SmoothingMode.AntiAlias; 5 g.FillRectangle(Brushes.White, this.ClientRectangle); 6 7 Pen p = new Pen(Color.Black, 10); 8 p.LineJoin = LineJoin.Bevel; 9 e.Graphics.DrawRectangle(p, 20, 20, 60, 60); 10 p.Dispose(); 11 }
显示的图形为:
可以用Brush(画笔)进行填充,如:
1 private void Form1_Paint(object sender, PaintEventArgs e) 2 { 3 Graphics g = e.Graphics; 4 g.SmoothingMode = SmoothingMode.AntiAlias; 5 SolidBrush b = new SolidBrush(Color.Crimson); 6 g.FillRectangle(b,20,20,40,40); 7 b.Dispose(); 8 }
填充一个深红色的矩形
