PHPExcel:以像素为单位设置行高

Question

我正在使用 PHPExcel 通过 PHP 将一组图像写入 Excel 文件。插入图像似乎不是问题，但是我在设置适当的行高以匹配图像高度时遇到了一些困难。

我设法使用 pixelsToCellDimension 来计算正确的列宽，但这似乎不适合计算行高。在检查了 PHPExcel_Shared_Drawing 类中的其余函数并谷歌搜索之后，我对如何执行此操作感到目瞪口呆。

到目前为止我的代码:

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Set document properties
$objPHPExcel->getProperties()->setCreator("creator")
    ->setLastModifiedBy("modifiedby")
    ->setTitle("Title")
    ->setSubject("Subject")
    ->setDescription("Description")
    ->setKeywords("keyword1 keyword2")
    ->setCategory("category");

// Get default font
$defaultFont = $objPHPExcel->getDefaultStyle()->getFont();

[生成我的图像并将它们的路径添加到数组的一些代码]

foreach( $filePaths as $i => $filePath ) {
    $objDrawing = new PHPExcel_Worksheet_Drawing();
    $objDrawing->setWorkSheet( $objPHPExcel->getActiveSheet() );
    $objDrawing->setName("name");
    $objDrawing->setDescription("Description");
    $objDrawing->setPath( $filePath );

    $size = getimagesize($filePath);
    $columnWidth = PHPExcel_Shared_Drawing::pixelsToCellDimension($size[0], $defaultFont);
    $rowHeight = PHPExcel_Shared_Drawing::pixelsToCellDimension($size[1], $defaultFont);

    $objDrawing->setCoordinates('A' . ($i+1) );
    $objDrawing->setOffsetX(0);
    $objDrawing->setOffsetY(0);

    // set row/column (cell) sizes to match image size
    $objPHPExcel->getActiveSheet()
       ->getColumnDimension('A')
       ->setWidth( $columnWidth );
    $objPHPExcel->getActiveSheet()
       ->getRowDimension( $i+1 )
       ->setRowHeight( $rowHeight );
}

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Worksheet 1');

// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);

// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="myMCS Scancode Export.xls"');
header('Cache-Control: max-age=0');

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;

我使用 pixelsToPoints 作为高度

$default_font = $spreadsheet->getDefaultStyle()->getFont();
$image_height = imageSY($image);
$image_width  = imageSX($image);
$image_height_pt = Drawing::pixelsToPoints($image_height);
$image_width_pt  = Drawing::pixelsToCellDimension($image_width,$default_font);

$drawing = new \PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing();
$drawing->setImageResource($image);
$drawing->setRenderingFunction(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::RENDERING_JPEG);
$drawing->setMimeType(\PhpOffice\PhpSpreadsheet\Worksheet\MemoryDrawing::MIMETYPE_DEFAULT);      
$drawing->setCoordinates($col.$row); 
$drawing->setHeight($image_height);
$drawing->setWorksheet($spreadsheet->getActiveSheet());
$spreadsheet->getActiveSheet()->getRowDimension($row)->setRowHeight($image_height_pt);
$spreadsheet->getActiveSheet()->getColumnDimension($col)->setWidth($image_width_pt);
