Opencv Mat to Id2d1Bimap Directx RRS feed

  • Question

  • I have to render opencv Mat to using DirectX 11.

    D2D1_BITMAP_PROPERTIES1 bitmapProperties = D2D1::BitmapProperties1(
                D2D1_BITMAP_OPTIONS_TARGET | D2D1_BITMAP_OPTIONS_CANNOT_DRAW,
                D2D1::PixelFormat(DXGI_FORMAT_B8G8R8A8_UNORM, D2D1_ALPHA_MODE_IGNORE),
                96,
                96
            );
    D2D1_SIZE_U s = D2D1::SizeU(640, 480);
    hr = m_d2DeviceContext->CreateBitmap(s, bitmapProp, &m_streamBitmap);
    

    I have to copy opencv matrix to m_streamBitmap. pImage is a color image with 3 channels.

    m_streamBitmap->CopyFromMemory(NULL, reinterpret_cast<BYTE*>(pImage.data),pImage.cols()*3);
    

    This gives distorted image as result. 

    Can anyone guide me with this.

    Thanks in advance ..
