PHPSpreadsheet-如何将链接中的图像放入Excel文件？

Question

我想将图像放在我的excel文件的单元格a1中。

我尝试了phpspreadsheet网站上的其他操作，但是都没有成功。 像来自他们的这个不起作用的示例。

$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
$drawing->setName('Paid');
$drawing->setDescription('Paid');
$drawing->setPath('https://pngimage.net/wp-content/uploads/2018/06/rfhnbyrb-png-6.png');
$drawing->setCoordinates('B15');
$drawing->setOffsetX(110);
$drawing->setRotation(25);
$drawing->getShadow()->setVisible(true);
$drawing->getShadow()->setDirection(45);

如果我创建一个带有文本的黑条，则可以使用此代码。

$gdImage = @imagecreatetruecolor(2000, 20) or die('Cannot Initialize new GD image stream');
$textColor = imagecolorallocate($gdImage, 255, 255, 5);
imagestring($gdImage, 1, 5, 5, date("F Y"), $textColor);

//  Add the In-Memory image to a worksheet
$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing();
$drawing->setName('In-Memory image 1');
$drawing->setDescription('In-Memory image 1');
$drawing->setCoordinates('A1');
$drawing->setImageResource($gdImage);
$drawing->setRenderingFunction(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::RENDERING_JPEG);
$drawing->setMimeType(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_DEFAULT);
$drawing->setHeight(36);
$drawing->setWorksheet($spreadsheet->getActiveSheet());

我尝试如何操作，但我的excel文件中没有图像，请谁想要帮助我。

我正在使用PHP 7.2中的phpspreedsheet和最新的phpspreedsheet版本。

<?php

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();

$IMG = 'https://pngimage.net/wp-content/uploads/2018/06/rfhnbyrb-png-6.png';
$row_num = 2;
if (isset($IMG) && !empty($IMG)) {
    $imageType = "png";

    if (strpos($IMG, ".png") === false) {
        $imageType = "jpg";
    }

    $drawing = new MemoryDrawing();
    $sheet->getRowDimension($row_num)->setRowHeight(80);
    $sheet->mergeCells('A'.$row_num.':H'.$row_num);

    $gdImage = ($imageType == 'png') ? imagecreatefrompng($IMG) : imagecreatefromjpeg($IMG);
    $drawing->setName('Company Logo');
    $drawing->setDescription('Company Logo image');
    $drawing->setResizeProportional(false);
    $drawing->setImageResource($gdImage);
    $drawing->setRenderingFunction(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::RENDERING_JPEG);
    $drawing->setMimeType(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_DEFAULT);
    $drawing->setWidth(211);
    $drawing->setHeight(40);
    $drawing->setOffsetX(5);
    $drawing->setOffsetY(30);
    $drawing->setCoordinates('C'.$row_num);
    $drawing->setWorksheet($spreadsheet->getActiveSheet());
    $row_num++;
}

$writer = new Xlsx($spreadsheet);
$writer->save('hello world.xlsx');

我为您找到了解决方案。但不幸的是，我找不到一种使用url而是图像本地化的方法。看看。

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();

$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
$drawing->setName('Paid');
$drawing->setDescription('Paid');
$drawing->setPath('images/paid.png'); // put your path and image here
$drawing->setCoordinates('B15');
$drawing->setOffsetX(110);
$drawing->setRotation(25);
$drawing->getShadow()->setVisible(true);
$drawing->getShadow()->setDirection(45);
$drawing->setWorksheet($spreadsheet->getActiveSheet());

$writer = new Xlsx($spreadsheet);
$writer->save('image.xlsx');

工作正常，请尽情享受：）

public struct Result<TResult>
{
    public static Result<TResult> Ok(TResult data) => new Result<TResult>(data, true);
    public static Result<TResult> Error() => new Result<TResult>(default(TResult), false);

    private Result(TResult data, bool success)
    {
        Data = data;
        Success = success;
    }

    public bool Success { get; }
    public TResult Data { get; }
}

public static class TaskExt
{
    public static async Task<Result<T>> AwaitSafe<T, TException>(this Task<T> task, Action<TException> handle)
        where TException : Exception
    {
        var result = Result<T>.Error();
        try
        {
            result = Result<T>.Ok(await task);
        }
        catch (TException ex)
        {
            handle.Invoke(ex);
        }

        return result;
    }
}
