This example loads a PLT file, with a pen widths and pen colors defined by the user. 

L_INT LFileSettings__SetPLTOptionsExample(L_TCHAR *pszPLTFileName, LBitmap* plBitmap, L_INT *pPenWidths, COLORREF *pPenColors)
{
   L_INT nRet;
   FILEPLTOPTIONS PltOptions; 
   L_INT  nPen; 
   /* Get the current PLT options */   
   nRet = LFileSettings::GetPLTOptions(&PltOptions, sizeof(PltOptions)); 
   if(nRet != SUCCESS)
      return nRet;
   for ( nPen = 0; nPen <  8; nPen++ ) 
   {
      /*Change pen width */
      PltOptions.PenWidth[nPen] = pPenWidths[nPen]; 
      /* Change pen color*/
      PltOptions.PenColor[nPen] = pPenColors[nPen]; 
   }
   /* Set new PLT options */
   nRet = LFileSettings::SetPLTOptions(&PltOptions); 
   if(nRet != SUCCESS)
      return nRet;
   /* Now load the PLT file */
