关于我的阴影效果,我需要一些帮助。我目前正在使用带阴影的控件进行旋转。但是当我旋转控件时,下拉阴影也会跟随该方向。这些是示例图像:
this is the normal look of the dropshadow when the user control is not yet rotated.
and this is the dropshadow after rotating the control
这是我用于该控件和阴影的代码:
<local:CogWheel x:Name="CogWheel2" Width="100" Height="100" GearColor="#FF4D5D" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="105,13,0,0" RenderTransformOrigin="0.5,0.5">
<local:CogWheel.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="100"/>
<TranslateTransform/>
</TransformGroup>
</local:CogWheel.RenderTransform>
<local:CogWheel.Effect>
<DropShadowEffect Color="#FF4D5D" BlurRadius="20" ShadowDepth="12" Direction="280" Opacity="0.70"/>
</local:CogWheel.Effect>
</local:CogWheel>
我想旋转控件,但保留其阴影方向。任何帮助,将不胜感激。谢谢!
编辑:
我自己解决了此问题,方法是将控件旋转到透明网格,然后将阴影添加到网格中。

我认为您可以在“阴影效果”方向上添加“角度”以保留效果
var rotate = (CogWheel2.RenderTransform as TransformGroup).Children.Where(x => x is RotateTransform).FirstOrDefault() as RotateTransform;
this.shadowEffect.Direction = 280 + rotate.Angle;

在父网格上应用阴影效果即可完成工作。
详细说明Justin CI的答案:将DropShadowEffect.Direction
绑定到RotateTransform.Angle
也是可行的。动画播放时很方便。
<local:CogWheel x:Name="CogWheel2" GearColor="#FF4D5D" RenderTransformOrigin="0.5,0.5">
<local:CogWheel.RenderTransform>
<RotateTransform Angle="100" x:Name="rotation"/>
</local:CogWheel.RenderTransform>
<local:CogWheel.Effect>
<DropShadowEffect Direction="{Binding Angle, ElementName=rotation}" Color="#FF4D5D" />
</local:CogWheel.Effect>
</local:CogWheel>
