Detailed Description

Function Documentation

§ convertFromD3D10Texture2D()

void cv::directx::convertFromD3D10Texture2D ( ID3D10Texture2D *  pD3D10Texture2D,
OutputArray  dst 
)

Converts ID3D10Texture2D to OutputArray.

Note
Note: function does memory copy from pD3D10Texture2D to dst
Parameters
pD3D10Texture2D- source D3D10 texture
dst- destination OutputArray

§ convertFromD3D11Texture2D()

void cv::directx::convertFromD3D11Texture2D ( ID3D11Texture2D *  pD3D11Texture2D,
OutputArray  dst 
)

Converts ID3D11Texture2D to OutputArray. If input texture format is DXGI_FORMAT_NV12 then data will be upsampled and color-converted to BGR format.

Note
Note: Destination matrix will be re-allocated if it has not enough memory to match texture size. function does memory copy from pD3D11Texture2D to dst
Parameters
pD3D11Texture2D- source D3D11 texture
dst- destination OutputArray

§ convertFromDirect3DSurface9()

void cv::directx::convertFromDirect3DSurface9 ( IDirect3DSurface9 *  pDirect3DSurface9,
OutputArray  dst,
void *  surfaceSharedHandle = NULL 
)

Converts IDirect3DSurface9 to OutputArray.

Note
Note: function does memory copy from pDirect3DSurface9 to dst
Parameters
pDirect3DSurface9- source D3D10 texture
dst- destination OutputArray
surfaceSharedHandle- shared handle

§ convertToD3D10Texture2D()

void cv::directx::convertToD3D10Texture2D ( InputArray  src,
ID3D10Texture2D *  pD3D10Texture2D 
)

Converts InputArray to ID3D10Texture2D.

Note
Note: function does memory copy from src to pD3D10Texture2D
Parameters
src- source InputArray
pD3D10Texture2D- destination D3D10 texture

§ convertToD3D11Texture2D()

void cv::directx::convertToD3D11Texture2D ( InputArray  src,
ID3D11Texture2D *  pD3D11Texture2D 
)

Converts InputArray to ID3D11Texture2D. If destination texture format is DXGI_FORMAT_NV12 then input UMat expected to be in BGR format and data will be downsampled and color-converted to NV12.

Note
Note: Destination texture must be allocated by application. Function does memory copy from src to pD3D11Texture2D
Parameters
src- source InputArray
pD3D11Texture2D- destination D3D11 texture
