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();
