Use Text-PDF-0.25 I use below code for produce pdf from a proper text file.

#!/usr/bin/perl
use Text::PDF::File;
use Text::PDF::Page;
use Text::PDF::Utils;       # not strictly needed
use Text::PDF::SFont;
$/=undef;
my $file1=shift;
open (SUSAM,"$file1");
my $ligne=<SUSAM>;

my @fischier=split(/\n/,$ligne);
my $pdf = Text::PDF::File->new;
$root = Text::PDF::Pages->new($pdf);
$root->proc_set("PDF", "Text");
$root->bbox(0, 0, 595, 840);
$page = Text::PDF::Page->new($pdf, $root);
$font = Text::PDF::SFont->new($pdf, 'Helvetica', 'F0');     
$root->add_font($font);
$i=800;
foreach(@fischier){
$page->add("BT 1 0 0 1 1 $i Tm /F0 13 Tf ('$_') Tj ET");
$i=$i-12;
}
$page->{' curstrm'}{'Filter'} = PDFArray(PDFName('FlateDecode'));
$pdf->out_file("c.pdf");
