Example

This example will toggle the use of pen and brush color red and blue for markers.

L_INT LVectorBase__SetMarkerExample(HWND hWnd, LVectorBase *pVector) 
{ 
   UNREFERENCED_PARAMETER(hWnd); 
   L_INT          nRet; 
   VECTORMARKER   Marker; 
   // Get marker settings 
   nRet = pVector->GetMarker(&Marker ); 
   if(nRet != SUCCESS) 
      return nRet; 
   // Toggle pen and brush color between red and blue 
   if( Marker.Pen.NewPen.LogPen.lopnColor == RGB( 0xFF, 0x00, 0x00 ) ) 
   { 
      Marker.Pen.NewPen.LogPen.lopnColor = RGB( 0x00, 0x00, 0xFF ); 
      Marker.Brush.BrushType.StandardBrush.LogBrush.lbColor = RGB( 0x00, 0x00, 0xFF ); 
   } 
   else 
   { 
      Marker.Pen.NewPen.LogPen.lopnColor = RGB( 0xFF, 0x00, 0x00 ); 
      Marker.Brush.BrushType.StandardBrush.LogBrush.lbColor = RGB( 0xFF, 0x00, 0x00 ); 
   } 
   Marker.dwFlags = Marker.dwFlags | VECTOR_MARKER_PEN_COLOR | VECTOR_MARKER_BRUSH_COLOR; 
   // Set new marker 
   nRet = pVector->SetMarker (&Marker ); 
   if(nRet != SUCCESS) 
      return nRet; 
   return SUCCESS;
