Dear CDOLAN, maybe I am doing something wrong but the inserted content is neither printed nor shown (except when choosing show form). Looking in the pdf -file i can find the content inserted as "form content" and as Text-stream. My colleagues and i were given an official form which has to be filled in and signed (later). We have to use the predefined fonts / sizes. So I was quite happy when i found CAM::PDF and some articles suggesting $pdf->fillFormFields(%data ) is doing exactly what we need. I try to develop the fill-in-tool on a Linux kollmann-nb 4.13.0-41-generic #46~16.04.1-Ubuntu SMP Thu May 3 10:06:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Please look attachments for detailed Perl-Version, perl-code source-pdf (Muster-10...) and generated pdf (test.pdf) ( Sorry but i'n not used to write in English) I am looking forward to hear from you.

Hi, I have looked into the issue, CAM::PDF::fillFormFields doesn't encode (compress) appearance stream. Even if there already was "Filter" entry in dictionary of (empty, as in this case) stream in original PDF. Thus, "Field content not visible" because stream can't be decoded. Strange that neither Acrobat nor other viewers complain. Easiest fix is to always compress either newly created or already existing, but to be updated, appearance. 2nd, attempts to fill e.g. checkboxes just won't work, because there's no code to do it -- only text fields are processed. It should be documented and/or warning issued. As to phone number being cropped, -- if suggested patch is applied -- see comment in 4538 line of 1.60 (current) version. Point is, obvious bug was easy to fix, anything else (e.g. "predefined fonts" - ??) is a bit more work and maybe beyond scope. #!/usr/bin/perl use strict; use warnings; use CAM::PDF; my $pdf = new CAM::PDF( 'Muster_10.pdf' ); my %data = ( '8118_Telefonnummer' => "0221 940 564 19", '4205_Auftrag' => "Hubba Hopp!\n Trallala Hoppsassa!", '4134_Kostentraegername' => "Test fuer Kostentraegername", ); $pdf->fillFormFields(%data ); $pdf->cleanoutput('test.pdf'); __END__ --- PDF_old.pm Thu Aug 15 05:08:26 2013 +++ PDF.pm Sat Jun 30 12:17:03 2018 @@ -4601,6 +4601,9 @@ $formdict->{Length} = CAM::PDF::Node->new('number', $len, $formonum, $formgnum); $formdict->{StreamData} = CAM::PDF::Node->new('stream', $text, $formonum, $formgnum); + delete $formdict-> { Filter }; + $self-> encodeObject( $formonum, 'FlateDecode' ); + if (@rsrcs > 0) { if (!$formdict->{Resources}) {
