怎么将指定位置的bmp图片像素值保存到一个二维数组中

void CImageBoardView::OnTest()

    bmpInfo.bmiHeader.biBitCount   =   32;   
    
    GetDIBits(pDC->m_hDC,hbmp,0,bmp.bmHeight,pData,&bmpInfo,DIB_RGB_COLORS);   
    UINT   color,   r,   g,   b;

    }   
    SetDIBits(pDC->m_hDC,   hbmp,0,   bmp.bmHeight,   pData,&bmpInfo,   DIB_RGB_COLORS);

    CString sos;                        //测试输出像素数组之一
