( #3333=superdoc: print w/ replies, xml ) Need Help??
I've previously written a rendering class that does does just that:
package PDF::ToText; use 5.006; use warnings; use strict; use CAM::PDF; use CAM::PDF::GS; use base qw(CAM::PDF::GS); =head1 NAME PDF::ToText - CAM::PDF renderer to extract PDF Text and position infor +mation =head1 VERSION Version 0.01 =cut our $VERSION = '0.01'; =head1 SYNOPSIS use CAM::PDF; use PDF::ToText; my $pdf = CAM::PDF->new($filename); my $contentTree = $pdf->getPageContentTree(1); $contentTree->render("PDF::ToText"); =head1 SUBROUTINES/METHODS =head2 renderText =cut sub _textToDevice { my $self = shift; my @t2u = $self->textToUser( @_ ); my @t2d = $self->userToDevice( @t2u); return @t2d; } sub renderText { my $self = shift; my $string = shift; my $width = shift; # collect vertices of this text segment. my @bottom_left = $self->_textToDevice(0, 0); my @bottom_right = $self->_textToDevice($width, 0); my @top_left = $self->_textToDevice(0, $self->{Tfs}); my @top_right = $self->_textToDevice($width, $self->{Tfs}); printf "%7.2f %7.2f %7.2f %7.2f %s\n", @bottom_left, @top_right, $s +tring; return; }
It's a drop in replacement for CAM::PDF::PageText.

In it's current state, it dumps text coordinates to STDOUT; but it can be easily amended to collect them in a global variable or whatever (CAM::PDF doesn't currently support the passing of handles).
