哪里可以下载Windows.Graphics.CaptureAPI的Delphi版本？

目前，Microsoft并未发布Windows.Graphics.Capture API的Delphi版本。不过，我们可以使用WinRT API来在Delphi中访问Windows.Graphics.Capture API。下面是一个简单的示例代码，展示如何在Delphi中使用WinRT API来捕获屏幕：

uses
  Winapi.Windows,
  Winapi.ActiveX,
  System.Win.WinRT,
  System.Win.WinRTEx;

procedure TForm1.CaptureScreen;
var
  screenRect: Windows.TRect;
  captureItem: Windows.Graphics.Capture.GraphicsCaptureItem;
  framePool: Windows.Graphics.Capture.Direct3D11.GraphicsCaptureFramePool;
  session: Windows.Graphics.Capture.Direct3D11.GraphicsCaptureSession;
begin
  screenRect := Windows.GetBoundsForMonitor(Windows.MonitorFromWindow(Self.Handle, MONITOR_DEFAULTTONEAREST));
  
  captureItem := Windows.Graphics.Capture.GraphicsCaptureItem.CreateFromVisual(WindowHandle);
  
  framePool := Windows.Graphics.Capture.Direct3D11.GraphicsCaptureFramePool.Create(
    Windows.Graphics.DirectX.DirectXPixelFormat.B8G8R8A8UIntNormalized, 2, screenRect.Size);
    
  session := Windows.Graphics.Capture.Direct3D11.GraphicsCaptureSession.Create(
    framePool, captureItem);
    
  framePool.StartCapture;
  session.StartCapture;
  
  // do something with captured frames...
  
  session.Close;
  framePool.Close;
end;

该代码中的CaptureScreen过程使用Windows API来获取屏幕矩形，并使用WinRT API来捕获该矩形的图像。注意，这个示例代码仅演示如何使用WinRT API来访问Windows.Graphics.Capture API，并不包含完整的屏幕捕获功能。
