Dear Sirs,
PDF::API2 version 0.53
module : lib/PDF/API2/Basic/PDF/File.pm

Many thanks for your impressive module. We are using it intensively to
process incoming documents automatically.
The case reported below may not be a bug, as it is quite possible that
the program creating such PDFs does not respect the specification.
I have checked in the Adobe PDF 1.4 reference, and it is not clear to me
wether the trailer tag *must* be followed by a CR.
In any case, the attached file is one of many that we receive from a
well-known supplier of on-line litterature, and it causes us a real
problem because these PDFs are systematically rejected.
Unfortunately, I don't feel confident enough to make a change in the
File.pm module to work around the issue, and I have little hope that
complaining to the document supplier would help.
The attached PDF is rejected by the File.pm module, around line 1257
[...]
if ($buf !~ /^trailer$cr/oi)
{ die "Malformed trailer in PDF file $self->{' fname'} at " .
($fh->tell - length($buf)); }
[...]
The reason seems to be that in the attached file, the "trailer" tag is
not immediately followed by a CR, but looks like this :
[...]

/Root 2 0 R

Thank you in advance and best regards,
