Overview

This module attempts to extract sequential text from a PDF page. This is not a robust process, as PDF text is graphically laid out in arbitrary order. 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.

All those disclaimers aside, it is useful for a quick dump of text from a simple PDF file.

Functions

$pkg->render($pagetree)

$pkg->render($pagetree, $verbose)

Turn a page content tree into a string. This is a class method that should be called like:

   CAM::PDF::PageText->render($pagetree);
