C#之GraphicsPath中Warp方法使用代码实例

    {
        public Form13()
        {
            InitializeComponent();
        }
        private void Form13_Paint(object sender, PaintEventArgs e)
        {
            // Create a path and add a rectangle.
            GraphicsPath myPath = new GraphicsPath();
            RectangleF srcRect = new RectangleF(0, 0, 100, 200);
            myPath.AddRectangle(srcRect);
            // Draw the source path (rectangle)to the screen.
            e.Graphics.DrawPath(Pens.Black, myPath);
            // Create a destination for the warped rectangle.
            PointF point1 = new PointF(200, 200);
            PointF point2 = new PointF(400, 250);
            PointF point3 = new PointF(220, 400);
            PointF[] destPoints = { point1, point2, point3 };
            // Create a translation matrix.
            Matrix translateMatrix = new Matrix();
            translateMatrix.Translate(100, 0);
            // Warp the source path (rectangle).
            myPath.Warp(destPoints, srcRect, translateMatrix,
                WarpMode.Perspective, 0.5f);
            // Draw the warped path (rectangle) to the screen.
            e.Graphics.DrawPath(new Pen(Color.Red), myPath);
        }
    }
}
          
            									
		
	

补充：软件开发 , C# ,

上一个：C#之shear的使用实例代码
下一个：C# 清理Recent文件实例代码
