You can get info from pdf in several ways. You can use swftools or
other library.
There are many libraries to work with pdf's for many languages.

One way, using python+swftools is, for example:

import sys
import gfx

if len(sys.argv) != 2:
    print "%s <file.pdf>" % sys.argv[0]
    print "Please give me a pdf document"

#gfx.setparameter("pages", "1")

doc = gfx.open("pdf", sys.argv[1])

for pagenr in range(1, doc.pages+1):
    page = doc.getPage(pagenr)
    npages.append("%dx%d" % (page.width, page.height))

# This will print the info to stdout with the following format:
#Total pages|page1 dimensions;page2 dimensions;.....;pageN dimensions
print "%d|%s" % (doc.pages, ";".join(npages))
