XAML用于旋转，圆形图像，透明中心

Question

我在寻找可以代表像vista一样的加载图标的xaml。

视觉描述：

• 圆形（在宽度约1/3英寸）
• 淡蓝色颜色
• 透明中心
• 凝胶按钮寻找（圆形边缘wtih一点阴影）
• 围绕边缘的白色旋转器，给予运动

light（er）sky blue/gel pack looking

我发现了旋转矩形，我们可以创建XAML，它给出了旋转的错觉，但我们只绘制了12个时钟部分，并且为每个动画制作了一个动画个别。

这里是一个超级简单的微调我在SL创建，你可以转换为WPF。

它绝对必须是全XAML吗？对于这种效应，透明的PNG工作起来非常棒。只需将PNG堆叠到网格中，并使用RotateTransform和DoubleAnimation为其中的一些设置动画。

如果您的应用程序不需要放大很多，那将是最简单的方法。
