添加直线的方法：
Brush t_brush=new SolidColorBrush(this.LineColor); // double p_sx = this.wfView.MapToScreen_X((double)rt_t.SX); double p_sy = this.wfView.MapToScreen_Y((double)rt_t.SY); // double p_ex = this.wfView.MapToScreen_X((double)rt_t.EX); double p_ey = this.wfView.MapToScreen_Y((double)rt_t.EY); // PointD eb = new PointD(); eb.X = (double)rt_t.SX; eb.Y = (double)rt_t.SY; PointD ee = new PointD(); ee.X = (double)rt_t.EX; ee.Y = (double)rt_t.EY; //画线(用面对象只添加两个点来完成) polygon t_line = new polygon(); // t_line.Points.Add(new Point(p_sx,p_sy)); t_line.Points.Add(new Point(p_ex,p_ey)); // t_line.Points.Add(new Point(p_sx,p_sy)); // //t_line.strokeThickness = 2; //t_line.Opacity = 0.5; //t_line.Width = 2; t_line.stroke = t_brush; t_line.Fill = t_brush; // this.cRoot.Children.Add(t_line);

Stream s = Application.GetResourceStream(new Uri(path,UriKind.Relative)).Stream;
img.SetSource(s);
//
Image ui_img = new Image();
ui_img.source = img;
//计算节点左上角坐标
double top_x = (int)p_x;

//

//画节点外边框
