i trying add logo image on generated excel worksheet using code listing below reason nothing 

    $objreader = phpexcel_iofactory::createreader('excel2007');     $objphpexcel = $objreader->load("workbooks/" . $labref . "/" . $labref . ".xlsx");     $objphpexcel->getactivesheet(2);     $objworksheet = $objphpexcel->createsheet();     $objworksheet->settitle("sample summary");             $dir1 = "exclusive_image";         $objdrawing = new phpexcel_worksheet_drawing();                 $objdrawing->setname("name");                 $objdrawing->setdescription("description");                 $objdrawing->setpath(base_url().'exclusive_image/nqcl.png');                 $objdrawing->setcoordinates('a1');                 $objdrawing->setworksheet($objworksheet->getactivesheet(2));         $objwriter = new phpexcel_writer_excel2007($objphpexcel);         $objwriter->save("workbooks/" . $labref . "/" . $labref . ".xlsx");

adding logo simple, try below code.

$objphpexcel = new phpexcel(); $sheet = $objphpexcel->setsheetindexandtitle(1, "your_sheet_title"); // first sheet $objdrawing = new phpexcel_worksheet_drawing(); $objdrawing->setname('logo'); $objdrawing->setdescription('logo'); $logo = base_path() . '/images/logo.png'; // provide path logo file $objdrawing->setpath($logo); $objdrawing->setoffsetx(8);    // setoffsetx works $objdrawing->setoffsety(300);  //setoffsety has no effect $objdrawing->setcoordinates('b1'); $objdrawing->setheight(75); // logo height $objdrawing->setworksheet($sheet);
