It appears that PDF::API2 does not support PDF 1.5 (and later) compression of the xref table. This type of file is more common since Acrobat 9 & 10 write them by default. The other compression scheme is compressed object streams.
I get the following error:
Malformed xref in PDF file at /opt/local/lib/perl5/site_perl/5.12.3/PDF/API2/Basic/PDF/File.pm line 1140.
Do any of the Perl PDF modules support reading a PDF with a compressed XRef?
CAM::PDF can read a compressed XRef. The documentation says:
I haven’t worked with CAM::PDF. But I looked it over and the api feels strange after coming from PDF::API2. It is more low level or something. There are advantages and disadvantages to both libraries though.
We use PDF::API2 at work and ask our designers to save as PDF v1.4 when they give us stuff. You can also use ghostscript to convert them to PDF 1.4 which is supported by PDF::API2.
