WPF中六边形填充颜色 [英] Filling Color in a hexagon in WPF

问题描述

我在使用此代码填充六边形时遇到问题，当此代码运行时，它只绘制白色"六边形的轮廓，我想用颜色填充六边形，但它不起作用.

I'm having problem in filling the hexagon using this code, when this code runs it draws only the outline of the hexagon that is "White", I want to fill the hexagon with a color but it is not working.

我搜索了很多并尝试了很多东西，例如 drawingContext.Drawing() 、drawingBrush 等

I have searched a lot and tried many things like drawingContext.Drawing() , drawingBrush, etc.

我在这段代码中遗漏了什么吗?这是代码:

Am I missing something in this code? This is the code:

public void DrawHexagon(DrawingContext drawingContext)
{
   GeometryGroup hexaKey = new GeometryGroup();

        //making lines for hexagon 
        hexaKey.Children.Add(
           new LineGeometry(new Point(X1, Y1), new Point(X2, Y2)));

        hexaKey.Children.Add(
            new LineGeometry(new Point(X2, Y2), new Point(X3, Y3)));

        hexaKey.Children.Add(
            new LineGeometry(new Point(X3, Y3), new Point(X4, Y4)));

        hexaKey.Children.Add(
            new LineGeometry(new Point(X4, Y4), new Point(X5, Y5)));

        hexaKey.Children.Add(
            new LineGeometry(new Point(X5, Y5), new Point(X6, Y6)));

        hexaKey.Children.Add(
            new LineGeometry(new Point(X6, Y6), new Point(X1, Y1)));

        //
        // Create a GeometryDrawing.
        //
        GeometryDrawing hexaKeyDrawing = new GeometryDrawing();
        hexaKeyDrawing.Geometry = hexaKey;

        // Paint the drawing with a gradient.
        hexaKeyDrawing.Brush =new SolidColorBrush(Colors.Red);


        // Outline the drawing with a solid color.
        hexaKeyDrawing.Pen = new Pen(Brushes.White, 2);


        drawingContext.DrawGeometry(hexaKeyDrawing.Brush, hexaKeyDrawing.Pen, hexaKeyDrawing.Geometry);

}

推荐答案

LineGeometry 无法填充……它们只是线条.你需要一条路.MSDN 有一个例子

LineGeometry doesn't have a way to fill... they're just lines. You need a path. The MSDN has an example
