Khen1950fx,
In short, yes. I am still playing but this was a significant step in the right direction. Please let me know what else you come up with.

Cheers - L~R

    Here's what I have now. I borrowed hdump from the examples directory of HTML::Parser. Then I used CAM::PDF::GS to make a gs log file.
    #!/usr/bin/perl use strict; use warnings; use CAM::PDF; use Data::Dumper::Concise; use base qw(CAM::PDF::GS::NoText); my $file = shift @ARGV; my $log = '/root/Desktop/gs.log'; binmode STDOUT, ":encoding(utf8)"; open STDOUT, '>', $log; my $pdf = CAM::PDF->new($file); my $contentTree = $pdf->getPageContentTree(5); my $gs = $contentTree->computeGS; print Dumper($gs): close STDOUT;
    From the cmdline do
    perl gscript.pl /path/to/pdf
    Then I used hdump to examine gs.log:
    #!/usr/bin/perl -w use strict; use HTML::TokeParser; use Data::Dumper::Concise; $| = 1; sub h { my ( $event, $line, $column, $text, $tagname, $attr ) = @_; my (@d) = uc( substr( $event, 0, 1 ) ) . " L$line C$column"; substr( $text, 40 ) = "..." if length $text > 40; push @d, $text; push @d, $tagname if defined $tagname; push @d, $attr if $attr; print Dumper(@d); } my $p = HTML::Parser->new( api_version => 3 ); $p->handler( default => \&h, "event, line, column, text, tagname, attr +" ); $p->parse_file( @ARGV ? shift : *STDIN );
    From the cmdline:
    perl hdump /path/to/gs.log
    I hope that it's useful for you.
