How can I convert first page of a pdf as its thumbnail?

I have a file field which allow users to upload document types like pdf, doc and txt. Now I want to convert first page of each document to a Thumbnail. I want this action either for CCK display and Views Field.
I already found some solution ( 1 , 2 , 3) but the two first are for Drupal 6 and the third one is just a php solution which I don't know how to make it work in my drupal7 system?
Now what should I do to make these type of thumbnails in Drupal7?

  • sure, but do you have any idea to use that php code which linked in that answer in drupal?!:( – Sheshkovsky Jan 13 '12 at 20:07
