This is trivial, but very annoying for beginners. In the synopsis, the example goes: ... # Add some text to the page $text = $pdf->text(); ... But should be ... # Add some text to the page $text = $page->text(); ... So the synopsis code doesn't actually work. While this may be unimportant for most, this is not the case for beginners. It's just a bad first impression, so beginners might be fooled into thinking PDF::API2 is bad quality.
