透明的UWP Windows 10 [英] Transparent UWP windows 10

问题描述

我试图弄清楚如何在应用程序上具有透明背景，以使用户可以在其后面看到。我试图更改 xaml background 和 opacity 参数>文件，但没有任何更改。

我也在后台设置了透明图像

 < Page.Background> 
< ImageBrush Stretch = Fill ImageSource = Assets / fond.png /> 
< /Page.Background> 
  

但这不起作用

更新：

在Fall Creators Update中，它甚至可以作为XAML代码使用，非常快速且易于编写。

I am trying to figure out how to have a transparent background on the app, that lets the user see behind it. I've tried to change background and opacity parameters in xaml file, but nothing changed.

I have set a transparent image in background also

<Page.Background>
    <ImageBrush Stretch="Fill" ImageSource="Assets/fond.png"/>
</Page.Background>

But it doesn't work

Does anyone know how to perform this?

You will be able to do it after the update of Windows 10 that is coming.

Here: https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/8232264-enable-blur-and-transparency-xaml-effects-to-allow?tracking_code=8e9425d1ccc153460b32b85ed3253c90

And the github: https://github.com/Microsoft/WindowsUIDevLabs/tree/master/SampleGallery/Samples/SDK%20Insider/BlurPlayground

Maybe it's not the straight "see through", but I think it's what you would like to have.

EDIT: I think it is available in the SDK Preview, but I'm not sure because I didn't try it.

UPDATE:

I've just noticed prelease of CreateHostBackdropBrush() function in Compositor class. https://docs.microsoft.com/en-us/uwp/api/windows.ui.composition.compositor

UPDATE:

In Fall Creators Update it's even available as XAML code that's very fast and easy to write.
