If emacs is compiled with --with-imagemagick it is possible.  But that's
pretty new in emacs's bzr trunk (2 weeks or so).  Have a look at the
README.imagemagick file and the info docs.

Yeah, doc-view also could make advantage out of that.

But the README.imagemagick leaves my with some further questions.  How
do I know if imagemagick support is compiled in?  Is

  (if (fboundp 'imagemagick-types) ... ...)

the way to go?

And if it's there, how do I know if `create-image' will actually use
imagemagick to load an image file?
And, how do I know if a given image is loaded by the imagemagick
