我想知道是否有可能以某种方式为给定的 xaml 控件的合成器调用此 API 函数: https ://msdn.microsoft.com/en-ca/library/windows/apps/mt620066?f=255&MSPPError=-2147217396
我在想的是这些方面的东西:
// Get the graphics device for the compositor
auto compositor = Window::Current().Compositor();
com_ptr<ICompositorInterop> comp_interop{ compositor.as<ICompositorInterop> };
com_ptr<ICompositionGraphicsDevice> m_compgd{nullptr};
comp_interop->GetGraphicsDevice(m_compgd.put()); // This doesn't actually exist.
// Get the rendering device
com_ptr<ICompositionGraphicsDeviceInterop> compgd_interop{m_compgd.as<ICompositionGraphicsDeviceInterop>()};
com_ptr<IUnknown> m_device{ nullptr };
check_hresult(
compgd_interop->GetRenderingDevice(m_device.put())
);
除了显然这不起作用,因为没有GetGraphicsDevice
可用的功能,只有CreateGraphicsDevice
.
