Constructors
The CD3D11_VIEWPORT class has these constructors.
| Constructor | Description |
|---|---|
| CD3D11_VIEWPORT() | Instantiates a new instance of an uninitialized CD3D11_VIEWPORT structure. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT_values)(FLOAT,FLOAT,FLOAT,FLOAT,FLOAT,FLOAT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with D3D11_VIEWPORT values. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT_values2)(ID3D11Buffer,ID3D11RenderTargetView,FLOAT,FLOAT,FLOAT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with D3D11_BUFFER_RTV values. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT_values3)(ID3D11Texture1D,ID3D11RenderTargetView,FLOAT,FLOAT,FLOAT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with D3D11_TEX1D_RTV or D3D11_TEX1D_ARRAY_RTV values. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT_values4)(ID3D11Texture2D,ID3D11RenderTargetView,FLOAT,FLOAT,FLOAT,FLOAT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with 2D texture values. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT_values5)(ID3D11Texture3D,ID3D11RenderTargetView,FLOAT,FLOAT,FLOAT,FLOAT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with 3D texture values. |
Methods
The CD3D11_VIEWPORT class has these methods.
| Method | Description |
|---|---|
| ~CD3D11_VIEWPORT() | Destroys an instance of a CD3D11_VIEWPORT structure. |
| CD3D11_VIEWPORT(D3D11_VIEWPORT)(const &D3D11_VIEWPORT) | Instantiates a new instance of a CD3D11_VIEWPORT structure that is initialized with a D3D11_VIEWPORT structure. |
| D3D11_VIEWPORT() | This operator returns the address of a D3D11_VIEWPORT structure that contains the data from the CD3D11_VIEWPORT instance. |
