       $objDrawing = new PHPExcel_Worksheet_Drawing();
       $objDrawing->setName('pg4');
       $objDrawing->setDescription('pg4');
       $objDrawing->setPath('./img/chk_true.png');
       $objDrawing->setCoordinates('D1');
       $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
       
       $objPHPExcel->getActiveSheet()->getStyle('D1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
       $objPHPExcel->getActiveSheet()->getStyle('D1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
