Here is what I have so far. When I tried to run it I got the error message Can't call method "getRootDict" on an undefined value..."

use CAM::PDF; 
use PDF::API2;


my $file_name = shift;


my $pdfone = CAM::PDF->new('pdfone.pdf');

for my $page (1 .. $pdfone->numPages()) {

my $text = $pdfone->getPageText($page);
@lines = split (/\n/, $text);

foreach (@lines) {
my $pdf = CAM::PDF->new('new.pdf');
$pdfone->appendPDF($pdf);
}
}
