Topic: Get image alt text and size

Posted by bkidd · 07-06-2020 - 13:04

I am currently using this to get the image alt text:

$referenceNode = array( 'customQuery' => '//w:drawing//wp:docPr', ); $contents = $docx->getDocxPathQueryInfo($referenceNode); foreach ($contents['elements'] as $content) { echo $content->getAttribute('descr'); }

I would also like to know the image dimensions. I have tried to use:

$images = (new Indexer($this->getPath()))->getOutput()['body']['images'];

which has the dimensions but I don't have a way to match the results.

Any suggestions? Thanks

Hello,

There's no option to match Indexer and getDocxPathQueryInfo output, but you can use the following method to get the image size from getDocxPathQueryInfo

$referenceNode = array( 'customQuery' => '//w:drawing//wp:docPr', );
$contents = $docx->getDocxPathQueryInfo($referenceNode);
foreach ($contents['elements'] as $content) {
        // get descr
        echo $content->getAttribute('descr') . PHP_EOL;;

        // get height and width
        $size = $content->parentNode->getElementsByTagNameNS('http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing', 'extent');
        if ($size->length > 0) {
                echo $size->item(0)->getAttribute('cx') . PHP_EOL; // width
                echo $size->item(0)->getAttribute('cy') . PHP_EOL; // height
        }
}

Images use EMUs as unit values, you can transform them to inches or cms using the following code:

'height_word_emus' => $heightImage,
'width_word_emus' => $widthImage,
'height_word_inches' => $heightImage/914400,
'width_word_inches' => $widthImage/914400,
'height_word_cms' => $heightImage/360000,
'width_word_cms' => $widthImage/360000,

Regards.
