画边框线条，有些问题...... [英] Draw lines with border, some problems ...

问题描述

您好，

我正在尝试绘制WPF Canvas，一些带边框的折线。

为此，我使用了StreamGeometry，一个PathGeometry和一个路径。

这是我的代码：

Hello,
I'm trying to draw in a WPF Canvas, some polylines with border.
For that purpose i've used a StreamGeometry, a PathGeometry and a "Path".
This is my code:

StreamGeometry geom = new StreamGeometry();

//this method fills the StreamGeometry with a polyline
DrawLines(geom, polyObj);

PathGeometry pathGeometry = geom.GetWidenedPathGeometry(new Pen(Brushes.Black, 10));
GeometryDrawing geoDrawing = new GeometryDrawing();
geoDrawing.Geometry = pathGeometry;

Path myPath = new Path();

myPath.Fill = Brushes.LightGreen;
myPath.Stroke = Brushes.Black;
myPath.StrokeThickness = 0.4;
myPath.Name = "tratta"+tratta.id;
myPath.Data = pathGeometry;
myPath.StrokeLineJoin = System.Windows.Media.PenLineJoin.Round;

canvas.Children.Add(myPath);

代码正常工作，但是当折线有两个以上的顶点时，我在结点上获得了这个图形问题：

如何解决这个问题？在此先感谢

The code is working, but when a polyline has more than two vertex, i obtain this graphic problems on a junction:

Image - Junction

How can i resolve this problems? Thanks in advance

推荐答案

canvasGeomentry.Child.Add(new Polyline())
{
Points=new PointCollection(new List(point))
{
new Point (x1,y1), new Point(x2,y2);
}
}
