C#中GraphicsPath的Warp方法用法实例
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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
usingSystem.Drawing.Drawing2D;
namespaceadvanced_drawing
{
publicpartialclassForm13:Form
{
publicForm13()
{
InitializeComponent();
}
privatevoidForm13_Paint(objectsender,PaintEventArgse)
{
//Createapathandaddarectangle.
GraphicsPathmyPath=newGraphicsPath();
RectangleFsrcRect=newRectangleF(0,0,100,200);
myPath.AddRectangle(srcRect);
//Drawthesourcepath(rectangle)tothescreen.
e.Graphics.DrawPath(Pens.Black,myPath);
//Createadestinationforthewarpedrectangle.
PointFpoint1=newPointF(200,200);
PointFpoint2=newPointF(400,250);
PointFpoint3=newPointF(220,400);
PointF[]destPoints={point1,point2,point3};
//Createatranslationmatrix.
MatrixtranslateMatrix=newMatrix();
translateMatrix.Translate(100,0);
//Warpthesourcepath(rectangle).
myPath.Warp(destPoints,srcRect,translateMatrix,
WarpMode.Perspective,0.5f);
//Drawthewarpedpath(rectangle)tothescreen.
e.Graphics.DrawPath(newPen(Color.Red),myPath);
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
