我正在尝试在 pdf 页面中添加水印.这是代码.

I am trying to add watermark in pdf page. here is the code.

$mpdf->SetDisplayMode('fullpage');

$mpdf->SetWatermarkText('DRAFT');
$mpdf->watermarkTextAlpha = 0.081;
$mpdf->watermark_font = 'DejaVuSansCondensed';

以上代码工作正常，但水印的大小相当大.我想让它变小.

我阅读了文档，但没有找到水印的字体大小.

I read the documentation but didn't found fontsize for watermark.

推荐答案

我通过修改mpdf.php中的watermark函数来设置水印字体大小:

I set the watermark fontsize by modifying watermark function in mpdf.php:

示例:

function watermark($texte, $angle = 45, $fontsize = 120, $alpha = 0.2) {
  $fontsize = 24
}
