Have a WPF Application ignore DPI settings
提问by Herrozerro
I have a wpf application that is designed for a 1900x1200 resolution but some of our users have used the windows display settings to resize everything by 125%-150%, is there a way to have an application ignore those settings and still display normally?
我有一个专为 1900x1200 分辨率设计的 wpf 应用程序，但我们的一些用户使用 Windows 显示设置将所有内容调整为 125%-150%，有没有办法让应用程序忽略这些设置并仍然正常显示？
I have seen something called SetProcessDPIAware here, but havent had any luck with it.
我在这里看到了一个叫做 SetProcessDPIAware 的东西，但没有任何运气。
Here is a screen shot of the application with the display scaling turned up to 150%
这是应用程序的屏幕截图，显示比例调至 150%
As you can see the application is way too small and there is no way to get it to be correctly sized.
如您所见，该应用程序太小了，无法使其大小正确。

Dpi awareness will not help in this case. It will only change CompositionTarget.TransformToDevice matrix, but controls sizes will not change.
在这种情况下，Dpi 意识将无济于事。它只会改变 CompositionTarget.TransformToDevice 矩阵，但控件大小不会改变。
I use view box to scale all content. All sizes in my app are designed for Surface Pro 3 portrait:
我使用视图框来缩放所有内容。我的应用程序中的所有尺寸都是为 Surface Pro 3 纵向设计的：
<Window>
<Viewbox Stretch="Uniform">
<Grid Width="1440" Height="2160">
<!-- ... -->
</Grid>
</Viewbox>
</Window>
You can calculate view box size basing on screen DPI. See this answer: https://stackoverflow.com/a/12414433/991267
