Looking at the docs at


http://www.graphicsmagick.org/api/types.html#imageinfo
http://www.graphicsmagick.org/formats.html

and the file /usr/include/GraphicsMagick/Magick++/STL.h

I'd say something like

imvec.begin().imageInfo().magick = "PNG"
Magick::writeImages (imvec.begin (), imvec.end (), "anyfilename");

should write a PNG format. I haven't tested it though
