Question

我已经问了一个问题，说如何绘制这种类型的圆圈， enter image description here 但是问题被保留为Hold，我想我没有详细描述这个圆圈，

基本上那是有四种颜色组合的圆圈，看起来像扇形的圆形组，希望我能得到答案，我也在尝试自己，我会自己回答它，如果它得到了解决，那么它也可以帮助其他人。

Answer 1

您可以大大简化代码。图中四个彩色部分中的每一个都是相同的，轮廓由三个拱形定义。绘制每个部分所有不同的是定义点和颜色：

private void Draw(Color color, Point point1, Point point2, Point point3, int radius)
{
    var pathFigure = new PathFigure();
    pathFigure.StartPoint = point1;

    ArcSegment arcSeg1 = new ArcSegment();
    arcSeg1.Point = point2;
    arcSeg1.Size = new Size(radius / 2, radius / 2);
    arcSeg1.SweepDirection = SweepDirection.Counterclockwise;

    ArcSegment arcSeg2 = new ArcSegment();
    arcSeg2.Point = point3;
    arcSeg2.Size = new Size(radius, radius);
    arcSeg2.SweepDirection = SweepDirection.Counterclockwise;

    ArcSegment arcSeg3 = new ArcSegment();
    arcSeg3.Point = point1;
    arcSeg3.Size = new Size(radius/2, radius/2);
    arcSeg3.SweepDirection = SweepDirection.Clockwise;

    pathFigure.Segments.Add(arcSeg1);
    pathFigure.Segments.Add(arcSeg2);
    pathFigure.Segments.Add(arcSeg3);

    var pathGeometry = new PathGeometry();
    pathGeometry.Figures.Add(pathFigure);
    var path = new Path();
    path.Fill = new SolidColorBrush(color);
    path.Data = pathGeometry;

    this.LayoutRoot.Children.Add(arcPath1);
}

用法：

Draw(Colors.Red, new Point(100, 100), new Point(100, 0), new Point(0, 100), 100);
Draw(Colors.Green, new Point(100, 100), new Point(0, 100), new Point(100, 200), 100);
Draw(Colors.Blue, new Point(100, 100), new Point(100, 200), new Point(200, 100), 100);
Draw(Colors.Yellow, new Point(100, 100), new Point(200, 100), new Point(100, 0), 100);

结果：

Answer 2

虽然我的代码看起来太长了，但它可能不是正确的解决方案但是给出了我想绘制的精确图形，

首先我绘制了Quardent，这个代码绘制了第一个Quardent，

        PathFigure pthFigure1 = new PathFigure();
        pthFigure1.StartPoint = new Point(0, 100);// starting cordinates of path figure
        ArcSegment arcSeg1 = new ArcSegment();
        arcSeg1.Point = new Point(100, 0);   // ending cordinates of arc segment point
        arcSeg1.Size = new Size(100, 100); // width and height of the arc
        arcSeg1.IsLargeArc = false;
        arcSeg1.SweepDirection = SweepDirection.Clockwise;
        LineSegment lineSeg = new LineSegment();
        lineSeg.Point = new Point(100, 100); //
        PathSegmentCollection myPathSegmentCollection1 = new PathSegmentCollection();
        myPathSegmentCollection1.Add(arcSeg1);
        myPathSegmentCollection1.Add(lineSeg);
        pthFigure1.Segments = myPathSegmentCollection1;
        PathFigureCollection pthFigureCollection1 = new PathFigureCollection();
        pthFigureCollection1.Add(pthFigure1);
        PathGeometry pthGeometry1 = new PathGeometry();
        pthGeometry1.Figures = pthFigureCollection1;
        System.Windows.Shapes.Path arcPath1 = new System.Windows.Shapes.Path();
        arcPath1.Data = pthGeometry1;
        arcPath1.Fill = new SolidColorBrush(Colors.Orange);
        this.LayoutRoot.Children.Add(arcPath1);

我分别画了其余的Quardent，然后我绘制半圆，在不同颜色的Quardent里面，像这样，

        PathFigure pthFigure5 = new PathFigure();
        pthFigure5.StartPoint = new Point(0, 100);// starting cordinates of arcs
        ArcSegment arcSeg5 = new ArcSegment();
        arcSeg5.Point = new Point(100, 100);   // ending cordinates of arcs
        arcSeg5.Size = new Size(50, 50);
        arcSeg5.IsLargeArc = true;
        arcSeg5.SweepDirection = SweepDirection.Clockwise;
        arcSeg5.RotationAngle = 30;
        PathSegmentCollection myPathSegmentCollection5 = new PathSegmentCollection();
        myPathSegmentCollection5.Add(arcSeg5);
        pthFigure5.Segments = myPathSegmentCollection5;
        PathFigureCollection pthFigureCollection5 = new PathFigureCollection();
        pthFigureCollection5.Add(pthFigure5);
        PathGeometry pthGeometry5 = new PathGeometry();
        pthGeometry5.Figures = pthFigureCollection5;
        System.Windows.Shapes.Path arcPath5 = new System.Windows.Shapes.Path();
        arcPath5.Data = pthGeometry5;
        arcPath5.Fill = new SolidColorBrush(Colors.Blue);
        this.LayoutRoot.Children.Add(arcPath5);

实际上是诡计，是在Quardent内画出半圈，然后是下面Quardent的颜色，完整代码看起来像这样。

        PathFigure pthFigure1 = new PathFigure();
        pthFigure1.StartPoint = new Point(0, 100);// starting cordinates of path figure
        ArcSegment arcSeg1 = new ArcSegment();
        arcSeg1.Point = new Point(100, 0);   // ending cordinates of arc segment point
        arcSeg1.Size = new Size(100, 100); // width and height of the arc
        arcSeg1.IsLargeArc = false;
        arcSeg1.SweepDirection = SweepDirection.Clockwise;
        LineSegment lineSeg = new LineSegment();
        lineSeg.Point = new Point(100, 100); //
        PathSegmentCollection myPathSegmentCollection1 = new PathSegmentCollection();
        myPathSegmentCollection1.Add(arcSeg1);
        myPathSegmentCollection1.Add(lineSeg);
        pthFigure1.Segments = myPathSegmentCollection1;
        PathFigureCollection pthFigureCollection1 = new PathFigureCollection();
        pthFigureCollection1.Add(pthFigure1);
        PathGeometry pthGeometry1 = new PathGeometry();
        pthGeometry1.Figures = pthFigureCollection1;
        System.Windows.Shapes.Path arcPath1 = new System.Windows.Shapes.Path();
        arcPath1.Data = pthGeometry1;
        arcPath1.Fill = new SolidColorBrush(Colors.Orange);
        this.LayoutRoot.Children.Add(arcPath1);


        PathFigure pthFigure2 = new PathFigure();
        pthFigure2.StartPoint = new Point(200, 100);// starting cordinates of path figure

        arcSeg2.Point = new Point(100, 0);   // ending cordinates of arc segment point
        arcSeg2.Size = new Size(100, 100); // width and height of the arc
        arcSeg2.IsLargeArc = false;
        arcSeg2.SweepDirection = SweepDirection.Counterclockwise;
        LineSegment lineSeg2 = new LineSegment();
        lineSeg2.Point = new Point(100, 100); //
        PathSegmentCollection myPathSegmentCollection2 = new PathSegmentCollection();
        myPathSegmentCollection2.Add(arcSeg2);
        myPathSegmentCollection2.Add(lineSeg2);
        pthFigure2.Segments = myPathSegmentCollection2;

        arcPath2.Data = pthGeometry2;
        arcPath2.Fill = new SolidColorBrush(Colors.Gray);
        this.LayoutRoot.Children.Add(arcPath2);

        PathFigure pthFigure3 = new PathFigure();
