pdf_info
Very simple wrapper to the pdfinfo unix tool, to provide the metadata information as a hash.
Usage
require 'pdf/info'
info = PDF::Info.new('/Users/tom/tmp/magazine.pdf')
pp info.metadataGives you the following output:
{
:version => 1.3,
:pages => [
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17],
[819.213, 1077.17]
],
:page_count => 12,
:encrypted => false
}Each of the pages has an individual size in PDF points - that's just how PDFs are. If you want more of the metadata that pdfinfo outputs, send us a patch.
If you need to manually set the path to the pdfinfo binary:
PDF::Info.command_path = "/usr/local/bin/pdfinfo"
