我正在创造有趣的轮盘赌游戏,我试图在其轴上(而不是360度)旋转带轮图像的日食。现在,它的轮换存在一些问题,它根据我的要求不能旋转。如果您将运行下面附带图像的代码。你会得到我的要求。
请设置您的屏幕分辨率,即Height =“1024”Width =“768”以了解我的确切要求。我也在这附上图片。一个是背景图像,另一个是轮图像。
从上一周开始,我就被困在了这个问题上。任何帮助都会很明显。提前谢谢。

据我了解,您希望椭圆在背景图像中的静态光盘位置旋转 完全 。此外,由于一点3D效果(透视效果),通常旋转椭圆将无法产生所需的结果。您可以尝试在WPF中使用某些3D功能,但这有点过分,因为我们还有其他选择。
您可以只旋转ImageBrush
,而不是旋转整个椭圆。我已经尝试过你的代码并稍微调整一下并进行一些修改,最后效果似乎就是你想要的。这是代码:
<Window.Resources>
<Storyboard x:Key="Storyboard1">
<DoubleAnimationUsingKeyFrames RepeatBehavior="Forever"
Storyboard.TargetProperty="Angle" Storyboard.TargetName="rot">
<EasingDoubleKeyFrame KeyTime="0:0:0" Value="0" />
<EasingDoubleKeyFrame KeyTime="0:0:2" Value="360" />
</DoubleAnimationUsingKeyFrames>

</Ellipse.RenderTransform>
<Ellipse.Fill>
<ImageBrush ImageSource="Image/Roullette_Wheel.jpg">
<ImageBrush.RelativeTransform>
<TransformGroup >
<RotateTransform CenterX="0.5" CenterY="0.5" x:Name="rot"/>
<SkewTransform/>
<TranslateTransform />
</TransformGroup>
</ImageBrush.RelativeTransform>
</ImageBrush>
</Ellipse.Fill>
<Ellipse.BitmapEffect>
<BevelBitmapEffect BevelWidth="0" />

您应该复制并尝试这个确切的代码,尝试扫描它与原始代码的某些差异。
