我试图在WPF中建模旧规模。因此我需要添加一个椭圆和一个矩形，我需要的只是切割量。 我尝试了Combined Geometry：
<Grid>
<Path Stroke="Black" StrokeThickness="1" Fill="#CCCCFF" Grid.ColumnSpan="3">
<Path.Data>
<CombinedGeometry GeometryCombineMode="Intersect">
<CombinedGeometry.Geometry1>
<EllipseGeometry RadiusX="50" RadiusY="50" Center="50,50" />
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<RectangleGeometry Rect="{Binding ElementName=recForm, Path=RenderedGeometry}" >
<RectangleGeometry.Transform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="45"/>
<TranslateTransform X="1" Y="1"/>
</TransformGroup>
</RectangleGeometry.Transform>
</RectangleGeometry>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</Path.Data>
</Path>
<Rectangle x:Name="recForm" Visibility="Hidden" Fill="#000000" Stroke="Black" StrokeThickness="1" RenderTransformOrigin="0.5,0.5" Margin="25,-11,25,11">
<Rectangle.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="45"/>
<TranslateTransform/>
</TransformGroup>
</Rectangle.RenderTransform>
</Rectangle>
</Grid>
但我什么也看不见。任何想法？

唯一不行的是设置锁定Canvas.Clip的角度到Canvas的角度
修改
现在一切正常。对于所有人来说，我编辑了上面的XAML代码，这是我的旋转方法。
private int setScaleBodyToBalance()
{
int balance = Program.TodayPresence.balanceWhenLeave();
int angle = 0;
if (balance >= 0) angle = 144 - balance / 150;
if (balance >= -5400 && balance < 0 ) angle = 144 + Math.Abs(balance) / 150;
if (balance < -5400) angle = -180 + (Math.Abs(balance) - 5400 )/ 150;
return angle;
}
public void updateShownInformation()
{
scaleBodyTransform.Angle = setScaleBodyToBalance();
}
余额是一个给我们时间的整数。当余额为3600时，时间是1:00 ......
