CAM::PDF::PageText - Extract text from PDF page tree
my $pdf = CAM::PDF->new($filename); my $pageone_tree = $pdf->getPageContentTree(1); print CAM::PDF::PageText->render($pageone_tree);

This module uses a few heuristics to try to guess what text goes next to what other text, but may be fooled easily by, say, subscripts, non-horizontal text, changes in font, form fields etc.
