IImagingFactory *pImgFac;

IImage *pImage;

ImageInfo info;

if(SUCCEEDED(CoCreateInstance(CLSID_ImagingFactory,NULL,CLSCTX_INPROC_SERVER,IID_IImagingFactory,(void **)&pImgFac)))

{

      if(SUCCEEDED(pImgFac->CreateImageFromBuffer(data,size,BufferDisposalFlagNone ,&pImage)))

      {

           pImage->GetImageInfo(&info);

           HDC hdc=::GetDC(NULL);

           HDC hMemdc=::CreateCompatibleDC(hdc);

           HBITMAP hImg=::CreateCompatibleBitmap(hdc,info.Width,info.Height);

           ::SelectObject(hMemdc,hImg);

           RECT rect  =  {  0 ,  0 , info.Width,info.Height};

           pImage -> Draw(hMemdc, &rect,NULL); 



           ::DeleteDC(hMemdc);

           ::DeleteDC(hdc);

           pImage->Release();

        }

        pImgFac->Release();
