bookmarkStyles

(mPDF ≥ 5.4)

Bookmarks can be styled by adding code as below to your script. You can define a colour (array of RGB) and/or a font-style ('B', 'I', or 'BI') for each level (starting at 0). Results may depend on the PDF Reader you are using.

Example

Set as a configuration variable

<?php
$config = [
    'bookmarkStyles' = [
        0 => array('color'=> array(0, 64, 128), 'style'=>'B'),
        1 => array('color'=> array(128, 0, 0), 'style'=>''),
        2 => array('color'=> array(0, 128, 0), 'style'=>'I'),
    ]
];

$mpdf = new \Mpdf\Mpdf($config);
