PHPExcel export网络或本地图片到excel

本例是在Laravel里面使用了use Excel;

1、此方法适用于项目文件夹下的图片

$img = "213123.png";

$objDrawing = new \PHPExcel_Worksheet_Drawing();

$objDrawing->setName('ZealImg');

$objDrawing->setDescription('Image inserted by Zeal');

$objDrawing->setPath($img);

$objDrawing->setHeight(250);

$objDrawing->setWidth(250);

$objDrawing->setCoordinates('A2');//单元格

$objDrawing->setOffsetX(20);//偏移量

$objDrawing->setOffsetY(20);

$objDrawing->setRotation(15);

$objDrawing->getShadow()->setVisible(true);

$objDrawing->getShadow()->setDirection(36);

$objDrawing->setWorksheet($sheet);//$sheet为当前工作表

2、此方法适用网络图片，通过GD创建画布的方式实现

$img = 'http://www.xxx.com/image/1.png';

$img = $this->imagecreatefrompng($img);

$width = imagesx($img);

$height = imagesy($img);

$sheet->setSize($cell,$width/5,$height);//设置单元格 宽高

$objDrawing = new \PHPExcel_Worksheet_MemoryDrawing();

$objDrawing->setName('Sample image');

$objDrawing->setDescription('Sample image');

$objDrawing->setCoordinates($cell);

$objDrawing->setImageResource($img);

$objDrawing->setOffsetX(10);

$objDrawing->setOffsetY(10);

$objDrawing->setRenderingFunction(\PHPExcel_Worksheet_MemoryDrawing::RENDERING_DEFAULT);//渲染方法

$objDrawing->setMimeType(\PHPExcel_Worksheet_MemoryDrawing::MIMETYPE_DEFAULT);

$objDrawing->setHeight($height);

$objDrawing->setWorksheet($sheet);//同上
