Again, you are not checking for errors. The documentation for getPageContentTree says (bold by me): Retrieves a parsed page content data structure, or undef if there is a syntax error or if the page does not exist. So, check for errors, and you should find the errors: `my $content = $pdf->getPageContentTree($page); if (! $content) { warn "Couldn't get content for page $page: $CAM::PDF::errstr"; # thanks to Anonymous Monk for pointing out the error variable } else { # process the page };` [download]	[reply] [d/l]
