Hello,

this question in not straightly related to Context, but Context users may have solved it and Ctx may be used to solve it.

I would need to get the following information from .pdf file(s):

- number of pages, - common width and height of pages (provided that they are the same; otherwise the dimension can be e.g. zero).

The final goal is to use Ctx as a .pdf joining engine - to provide this, I need to know whether the .pdf to be inserted is portrait or landscape oriented, what is its size (so if to be scaled or not) etc.

So Lua inside Ctx may be used to get the required .pdf info, if necessary.

If an external program was used, it should be non-interactive (command-line oriented), free and working under Windows.

Does anyone have any experience with such a task? You can use some macros (see Taco), and for external programs google for mupdf and xpdf

Tthe lua pdf library with mkiv should be also useful, but I've still to play with it.

luatex's epdf library (= poppler Lua bindings, maybe that's what Luigi meant) allows to extract all this info from a pdf file, with a bit of Lua programming.
