通用Windows应用程序中的投影效果 [英] Drop Shadow effect in Universal Windows Application

问题描述

我正在寻找一种仅使用XAML在WPF中添加投影效果的简便方法。我想将其应用于ListView中的元素。

I'm looking for an easy way to add a Drop Shadow effect like in WPF, using XAML only. I would like to apply it for the elements in a ListView.

除了这样的实验，我什么都找不到：

I haven't found anything more than experiments like this: https://blogs.windows.com/buildingapps/2016/09/12/creating-beautiful-effects-for-uwp/#BIRDSebvmJwAFY5Y.97

似乎需要很多代码-背后。我想避免它。

It seems that it would requiere a lot of code-behind. I would like to avoid it. 

推荐答案

如果您想自己使用Composition API进行操作，确实可以完成很多工作。幸运的是，我们有了一个很棒的社区，而这些开源项目之一就是 UWP社区工具包。该工具包包含一个 DropShadowPanel 控件，它可以为您完成辛苦的工作。

If you want to do it yourself with the Composition API, it's quite some work indeed. Luckily we got a great community, and one of those open source projects is the UWP Community Toolkit. This toolkit contains a DropShadowPanel control that does the hard work for you.

<controls:DropShadowPanel BlurRadius="4.0"
                          ShadowOpacity="0.70"
                          OffsetX="5.0"
                          OffsetY="5.0"
                          Color="Black">
    <Image Width="200" Source="Unicorn.png" Stretch="Uniform"/>
</controls:DropShadowPanel>    

请注意，您必须为此将应用程序版本设置为10.0.14393.0（周年更新）效果。

Note that you'll have to set the app version to 10.0.14393.0 (Anniversary Update) for this effect.
