how to use LRasterPaintWindow and LBitmapWindow together?

 CWnd m_ImgWnd;

 LBitmapWindow m_LeadImgWnd;

LRasterPaintWindow  *  m_RasterPntWnd;
 m_LeadImgWnd.Create(_T("STATIC"), _T(""), WS_CHILD | WS_VISIBLE,
  CRect(0, 0, 300, 300), this, 1234);
 
 m_BitmapImg.SetWndHandle(m_ImgWnd.m_hWnd);

 m_BitmapImg.SetFileName(TEXT("F:\\LeadTool_Study\\HowTO\\Lead15\\mm.bmp"));

 m_BitmapImg.Load();

 int res
 m_RasterPntWnd = new LRasterPaintWindow;
 res = m_RasterPntWnd->Initialize();
 
 res = m_RasterPntWnd->SetBitmap( &m_BitmapImg );
 res = m_RasterPntWnd->SetWndHandle( m_LeadImgWnd.GetSafeHwnd() );
 m_BitmapImg.SetPatternBackColor(RGB(255,247,220));

 m_BitmapImg.EnableAutoScroll(FALSE);
 m_BitmapImg.SetZoomMode(ZOOM_FIT);
 m_BitmapImg.Paint();

my question:Can I write code like this  res = m_RasterPntWnd->SetBitmap( &m_BitmapImg );?

but it can not display the image.only  m_BitmapImg.SetPatternBackColor(RGB(255,247,220)); works.

You can pass a LBitmapWindow object to
LRasterPaintWindow::SetWndHandle because it's derived from LBitmapBase.
However, the bitmap should be drawn in the RasterPaint window, not the LBitmapWindow itself.
