How to find if PDF has orientation or portrait

Question

Are there tools to determine if a PDF has a landscape or portrait orientation?

I am currently looking at pdfbox and Itext , but it seems I could not find it. Tell me if they support it.

Retrieving PDF information using Origami provides information that PDF pages have some rotation. Here is what Origami reports:

{:Parent=>#<PDF::Reader::Reference:0x872349c @id=8, @gen=0>, :Type=>:Page, 
 :Contents=>#<PDF::Reader::Reference:0x8722f24 @id=4, @gen=0>, :Resources=># <PDF::Reader::Reference:0x870dbd8 @id=2, @gen=0>, 
:MediaBox=>[0, 0, 612, 792], :Rotate=>270}

Turn: 270

What does rotation mean?
