本文实例讲述了C#中GraphicsPath的Warp方法用法。分享给大家供大家参考。具体实现方法如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
namespace advanced_drawing
{
public partial class Form13 : Form
{
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);
}
}
}
