you can use purpose "$mpdf->y" (current position in user unit cell positioning):

$mpdf=new mpdf('', 'a4'); $mpdf->writehtml('line1<pagebreak>line2<br>line3'); // $unusedspaceh = $mpdf->h - $mpdf->y - $mpdf->bmargin; $unusedspacew = $mpdf->w - $mpdf->lmargin - $mpdf->rmargin; // $mpdf->rect($mpdf->x, $mpdf->y, $unusedspacew, $unusedspaceh); $mpdf->output();
