导出Laravel excel图像失败

正在尝试通过laravel excel导出我的daanswerdata。 https://docs.laravel-excel.com/3.1/getting-started/- 这是我用来参考的文档。起初,它运行成功,但当我打开导出的文件时,它会导出图像的路径,而不是导出实际的图像。是否有方法导出图像(png文件)?

这是导出的文件

这是保存图像的本地路径文件夹

在我的数据库中是这样的 .

这是我的代码:

1.出口。php

<?php

namespace App\Exports;

use App\Models\signature;
use Maatwebsite\Excel\Concerns\FromCollection;

//frow laravel excel  drawing(image export) 
use PhpOffice\PhpSpreadsheet\Worksheet\Drawing;
use Maatwebsite\Excel\Concerns\WithHeadings;

use Maatwebsite\Excel\Concerns\WithColumnWidths;





class SignatureExport implements FromCollection,  WithHeadings, WithColumnWidths
{
    /**
    * @return \Illuminate\Support\Collection
    */
    public function collection()
    {
        return signature::all();
    }


    public function drawings()
    {
    

        $drawing = new Drawing();

    
        $drawing->setName('signature');
        $drawing->setDescription('This is my signatuer');
        $drawing->setPath(public_path('/uploads/signatures'));
        
        $drawing->setHeight(90);
        $drawing->setCoordinates('D1');

        return $drawing;
    }

    public function headings(): array
    {
        return [
            'id',
            'name',
            'description',
            'signature',
            'created_at',
            'updated_at',
        ];
    }

    public function columnWidths(): array
{
    return [
        'A' => 30,
        'B' => 30,        
        'C' => 30,
        'D' => 30,    
        'E' => 30,          
    ];
}


}

2、出口控制器

   public function exportexcel()
    {

        return Excel::download(new SignatureExport, 'signaturelist.xlsx');

    }

我错过什么了吗?感谢您的回答。

用被接受的答案解决了问题。 但是出现了新的问题

仅成功导出了1个图像,而不是3个图像

<?php

namespace App\Exports;

use App\Models\signature;
use Maatwebsite\Excel\Concerns\FromCollection;

//frow laravel excel  drawing(image export) 
use PhpOffice\PhpSpreadsheet\Worksheet\Drawing;

use Maatwebsite\Excel\Concerns\WithDrawings;

use Maatwebsite\Excel\Concerns\WithHeadings;

use Maatwebsite\Excel\Concerns\WithColumnWidths;

use Maatwebsite\Excel\Concerns\WithColumnFormatting;






class SignatureExport implements FromCollection,  WithHeadings, WithColumnWidths, WithDrawings
{
    /**
    * @return \Illuminate\Support\Collection
    */
    public function collection()
    {
        return signature::all();
    }


    public function drawings()
    {
    

        $drawing = new Drawing();

        $drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
        $drawing->setName('signature');
        $drawing->setDescription('This is my signatuer');
        $drawing->setPath(public_path('/uploads/signatures/62ac8a575af1a.png'));
        
        $drawing->setHeight(90);
        $drawing->setCoordinates('D1');

        return $drawing;
    }

    public function headings(): array
    {
        return [
            'id',
            'name',
            'description',
            'signature',
            'created_at',
            'updated_at',
        ];
    }

    public function columnWidths(): array
{
    return [
        'A' => 30,
        'B' => 30,        
        'C' => 30,
        'D' => 30,    
        'E' => 30,          
    ];
}


}

我应该怎么做才能导出所有图像?
