如何在phpexcel中显示数据库中的长blob图像？

Question

我有一个表存储长blob类型的图像数据，如何检索phpexcel中的图像显示？我的代码示例：

$order = "SELECT * FROM tblorder";

$tblorder = $conn->query($order);
$row_order = $tblorder->fetch(PDO::FETCH_ASSOC);
$image =$row_order["image"];
$data = base64_encode($image);

$objDrawing = new PHPExcel_Worksheet_MemoryDrawing();
$objDrawing->setName('image');
$objDrawing->setDescription('image');
$objDrawing->getIndexedFilename($data);
$objDrawing->setRenderingFunction(PHPExcel_Worksheet_MemoryDrawing::RENDERING_JPEG);
$objDrawing->setMimeType(PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT);
$objDrawing->setCoordinates('A85');
$objDrawing->setWorksheet($sheet->getActiveSheet());
