如何获取所有支持的DPI /分辨率的列表 [英] How to get a list of all supported DPI/resolution

问题描述

如何获取所有支持的DPI /分辨率的列表？例如在Windows 10上用于DPI列表：有四种选择：100％，125％，150％，175％

How to get a list of all supported DPI/resolution? e.g. on windows 10 for DPI list: there are four choices: 100%, 125%, 150%, 175%

您好，

感谢您发布MSDN论坛。

Thank you for posting MSDN forum.

根据您的说明，  I 无法得到你的意思，你想在一个进程或一个应用程序中启用不同的DPI缩放模式吗？

According to your description, I cannot get your mean, Did you want to enable the use of different DPI scaling modes within a single process or one application ?

如果是，你可以尝试使用
SetThreadDpiAwarenessContext 方法。

If yes, you can try to use SetThreadDpiAwarenessContext method.

例如，应用程序的主要顶级窗口可以基于每个监视器进行缩放，而辅助顶级窗口可以通过操作进行位图缩放来缩放系统。

For example, an application's primary top-level window could be scaled on a per-monitor basis while secondary top-level windows could be scaled via bitmap-scaling by the operating system.

使用 SetThreadDpiAwarenessContext 的常见方案如下：从一个运行一个上下文的线程开始（例如
DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE ）暂时切换到其他上下文（ DPI_AWARENESS_CONTEXT_UNAWARE ），创建一个窗口，然后立即将线程上下文切换回其先前的状态。创建的窗口
将具有 DPI_AWARENESS_CONTEXT_UNAWARE 的DPI上下文，而调用线程的上下文将恢复为
DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE ，随后调用
SetThreadDpiAwarenessContext 。

A common scenario for the use of SetThreadDpiAwarenessContext is as follows: Begin with a thread that is running with one context (such as DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE) temporarily switch to a different context (DPI_AWARENESS_CONTEXT_UNAWARE), create a window, and then immediately switch the thread context back to its previous state. The created window will have a DPI context of DPI_AWARENESS_CONTEXT_UNAWARE, while the calling thread’s context will be restored to DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE with a subsequent call to SetThreadDpiAwarenessContext.

最佳 此致，
