Hi Paul, i found this 2 problems with the annotations in TCPDI:

In line 286, instead of

&& is_array($annots[1][1]) && count($annots[1][1] > 1)

it should be:

&& is_array($annots[1][1]) && (count($annots[1][1]) > 1)

And in line 293 to 295 instead of

foreach ($annots[1][1] as $annot) {
$this->importAnnotation($annot);
}

there should a conditional to check the annotations are not null:

foreach ($annots[1][1] as $annot) {
if($annot != null){
$this->importAnnotation($annot);
}
}

This prevents an error that occurs when using this function when there are no annotations.

Thanks for all you have shared man!
