convertFromD3D10Texture2D()

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

#include <opencv2/core/directx.hpp>

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
	)

#include <opencv2/core/directx.hpp>

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
