Special case - rotated Portrait headers on Landscape pages
<?php $mpdf->forcePortraitHeaders = true;
This is a quick fix which rotates HTML headers and Footers (only - not normal ones) on landscape pages in the following conditions:
- document orientation is portrait
- when adding a page, you must only call
<pagebreak orientation="landscape" />
If you try to set new margins/headers etc. for new landscape pages when variable
$forcePortraitHeaders = true, it will go wrong.
