无论如何我有一个旋转动画的PathGeometry,由弧和线段(饼)从角度a到角度B?
PathGeometry是用c#而不是xaml绘制的,所以用c#而不是xaml的答案会很受欢迎,并且动画需要在加载时播放
不确定我是否错过了什么:你不能把RotateTransform
应用到Transform
,然后动画Angle
属性?如:
<Path Stroke="Black" StrokeThickness="5" Width="100" Height="100">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="RotationStates">
<VisualState x:Name="RotatingState">
<Storyboard Duration="0:0:1" RepeatBehavior="Forever" AutoReverse="True">
<DoubleAnimation Storyboard.TargetName="rotateTransform"
Storyboard.TargetProperty="Angle"
To="45"
/>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<i:Interaction.Triggers>
<i:EventTrigger EventName="Loaded">
<ei:GoToStateAction StateName="RotatingState" />
</i:EventTrigger>
</i:Interaction.Triggers>
<Path.Data>
<PathGeometry>
<PathGeometry.Transform>
<RotateTransform x:Name="rotateTransform" Angle="0" />
</PathGeometry.Transform>
<PathFigure StartPoint="10,10">
<LineSegment Point="50,0" />
</PathFigure>
</PathGeometry>
</Path.Data>
</Path>
