Subject: total pages in external PDF
Date: Wed, 25 Feb 2015 18:41:46 +0100	[thread overview]
Message-ID: <54EE095A.7080607@gmx.es> (raw)

Dear list,

I need to get the number of pages from an external PDF file that I also
define with an \env.

I think I could get something like this.:

    \def\Myfilename{\env{filename}}
    doc = epdf.open(arg[\MyFilename])
    total_pages_ =  doc:getNumPages()
    \def\Mypages{total_pages}

But mixing both lua and ConTeXt commands the wrong way won’t work.

Sorry, but this is all Greek to me. Although I see how it could be done,
I cannot write the code for this.

Which is the right way to get the code above working?

Many thanks for your help,


Pablo
