[h-e-w] C-x C-f foo.pdf?

[Raymond Zeitler]

When I open a PDF file, I see the binary file content.  Yet apparently it's 
possible to view the human-readable content.  For example, the following is 
quoted from Sacha Chua's transcript of her Skype conversation about Emacs with 
John Wiegley.

"J: I just started playing around with [Emacs'] ability to view PDF files. You 
can use C-x C-f to open a PDF file and you'll see it in your Emacs. It renders 
them page by page as PNG files, and then uses the Imagemagick extension built 
into Emacs 24 to show you those pages."[1]

I'm running version 24.1.1 pre-compiled binary on Windows 7 64-bit (SP1).  Do I 
need to re-build Emacs with different options in order to render PDF?  I also 
have The GIMP installed and running on the same system.  Just curious.
