RECT clientRect,rect;
    HDC hDC = GetDC(hwnd);
    HDC hMemDC = CreateCompatibleDC(hDC);
    ::SelectObject(hMemDC, bmp);
    GetClientRect(hwnd, &clientRect);
StretchBlt(hDC, clientRect.left, clientRect.top, newwidth, newheight, hMemDC, 0, 0,bmpdata.bmWidth, bmpdata.bmHeight,SRCCOPY);

Use ExcludeClipRect to clip out the area of the image, and then fill the background around it using FillRect.
