PDF problems

[spider]

Hi!
I need some help. In code c++ i need to ask number of pages in pdf-file, something like : system("identify -format %n some.pdf"); but without use 'system' if this possible? And how?
Thank you.

Try this:

• list<Image> imageList;
  readImages( &imageList, srcdir + "smile_anim.miff" );
  cout << "Total pages: " << imageList.size() << endl;

The the ping() method instead of readImages() if you only want the number of pages.
