推荐答案
标准的效果库提供了 DropShadowEffect OuterGlowBitmapEffect 的c $ c>。关于这种效果的好处是它是硬件加速的（与位图效果不同，后者是在软件中完成的）。要使 DropShadowEffect 看起来像光晕，只需将 ShadowDepth 属性设置为0。
The standard Effect library provides a DropShadowEffect that can be set up to look just like an OuterGlowBitmapEffect. The nice thing about this effect is that it is hardware-accelerated (unlike the bitmap effects, which are done in software). To make the DropShadowEffect look like a glow, simply set the ShadowDepth property to 0.
