IDirect3DSurface Interface

Definition

Namespace:

Windows.Graphics.DirectX.Direct3D11

This represents an IDXGISurface and can be used to interop between Windows Runtime components that need to exchange IDXGISurface references.

Examples

// Create a new Windows Console Application (C++/WinRT) project, and
// replace the contents of `pch.h` and `main.cpp` source code files with the code below.
// Be aware that the code below omits the details of obtaining a WinRT Direct3DSurface in
// the first segment of code, and obtaining a native DirectX surface in the second segment.
// The code shows only how to perform the conversion between the two.

Remarks

To move back and forth between IDirect3DSurface and IDXGISurface, use the CreateDirect3DSurface and GetDXGIInterface(IDirect3DSurface^, DXGI_TYPE**) functions.

Properties

Description

Gets a Direct3DSurfaceDescription describing the surface.

Methods
