How can I take a screenshot of a complete PDF file?

I want to take a screenshot of a PDF file that has three pages.

How could I combine the three pages into one single screenshot?


Windows 7 natively has "Snipping tool" (under accessoires) that you can use to gather each page (or section of page) and then paste with paint to a new image. Each "New image" automatically puts it in the paste buffer. You could also print the selected pages to a new PDF, if you have configured a generic PDF printer.
