Silverlight 引路蜂二维图形库示例:路径

引路蜂二维图形库也提供了对一般路径的支持，可以同过线段，二次曲线，三次曲线组成路径，也可以根据SVG指令来定义路径。

private void Paths() 
{ 
 AffineTransform mat1; 
  
 /* The path.  */
 Path path; 
  
 /** Colors */
 Color redColor = new Color(0x96ff0000,truE); 
 Color greenColor = new Color(0xff00ff00,falsE); 
 Color blueColor = new Color(0x750000ff,truE); 
  
 String pathdata = 
    "M 60 20 Q -40 70 60 120 Q 160 70 60 20 z"; 
 mat1 = new AffineTransform(); 
 mat1.Translate(30,40); 
 mat1.Rotate(-30 * Math.PI / 180.0); 
 path = Path.FromString(pathdata); 
 //Clear the canvas with white color. 
 graphics2D.Reset(); 
 graphics2D.Clear(Color.WhitE); 
  
 graphics2D.AffineTransform = new AffineTransform(); 
 SolidBrush brush = new SolidBrush(greenColor); 
 graphics2D.Fill(brush,path); 
 graphics2D.AffineTransform = mat1; 
  
 brush = new SolidBrush(blueColor); 
 Pen pen = new Pen(redColor,5); 
 graphics2D.SetPenAndBrush(pen,brush); 
 graphics2D.Draw(null,path); 
 graphics2D.Fill(null,path); 
}
