照片编辑器应用程序是一个通用 Windows 平台 (UWP) 示例应用程序，它通过 C++/WinRT 语言投影展示开发。The Photo Editor application is a Universal Windows Platform (UWP) sample application that showcases development with the C++/WinRT language projection. 此示例应用程序允许你从图片库检索照片，然后使用分类的照片效果编辑选择的图像。The sample application allows you to retrieve photos from the Pictures library, and then edit the selected image with assorted photo effects. 在示例的源代码中，你将看到大量的常见做法 — 如数据绑定和异步操作— 使用 C++/WinRT 投影执行。In the sample's source code, you'll see a number of common practices—such as data binding, and asynchronous actions and operations—performed using the C++/WinRT projection. 下面是示例演示的一些特定功能。Here are some of the specific features demonstrated by the sample.
- 通过 Windows 运行时 (WinRT) API 使用标准 C++17 语法和库。Use of Standard C++17 syntax and libraries with Windows Runtime (WinRT) APIs.
- 使用协同程序，包括使用 co_await、co_return、IAsyncAction和IAsyncOperationTResult <> 。Use of coroutines, including the use of co_await, co_return, IAsyncAction, and IAsyncOperation<TResult>.
- 创建和使用自定义 Windows 运行时类（运行时类）投影类型和实现类型。Creation and use of custom Windows Runtime class (runtime class) projected types and implementation types. 有关这些术语的详细信息，请参阅通过 C++/WinRT 使用 API 和使用 C++/WinRT 创作 API。For more info about these terms, see Consume APIs with C++/WinRT and Author APIs with C++/WinRT.
- 事件处理，包括使用自动撤销事件令牌。Event handling, including the use of auto-revoking event tokens.
- 使用外部 Win2D NuGet 程序包和 Windows::UI::Composition 呈现图像效果。Use of the external Win2D NuGet package, and Windows::UI::Composition, for image effects.
- XAML 数据绑定，包括 {x:Bind} 标记扩展。XAML data binding, including the {x:Bind} markup extension.
- XAML 样式和 UI 自定义，包括连贯动画。XAML styling and UI customization, including connected animations.
