Image I/O from stdin

Can a Magick::Image be read/written from/to stdin? In the
Image class in
Magick++ I only saw read()/write() methods to blobs and
files, but no
overloaded operator<<()/operator>>(). I don't
know the internals of
Magick++, and I suspect this might not even be possible,
unless the format
of the image being read is known a priori.

I want to do something like this:

some_application | my_ImageMagic++_application | xv -

where some_application outputs an image,
my_ImageMagic++_application reads
it from stdin, and outputs another image, which finally is
piped into xv
for viewing.

Thanks!

Never mind, I figured it out. I can use
Image::read("-") or e.g.
Image::write("-"). 

cin >> image;
or 
cout << image;

would have looked a little more c++, but read/write is fine.
