#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName
L_INT LVectorWindow__RepaintExample(HWND hWndParent, LVectorWindow *pVectorWindow)
{
   UNREFERENCED_PARAMETER(hWndParent);
   //Load and scale an image
   L_INT       nRet;
   VECTORPOINT scalePoint = {3.0, 1.0, 1.0, 0};
   pVectorWindow->EnableAutoPaint(FALSE);
   nRet = pVectorWindow->Load(MAKE_IMAGE_PATH(TEXT("random.dxf")));
   if(nRet != SUCCESS)
      return nRet;
   nRet = pVectorWindow->SetScale(&scalePoint);
   if(nRet != SUCCESS)
      return nRet;
   //Now paint the image
   pVectorWindow->EnableAutoPaint(TRUE);
   pVectorWindow->Repaint();
   return SUCCESS;
