Rendering Canvas to pixmap

[Moonshade <alexp inbox lv>]

Hello everyone!
Got a question about canvas here.
Is it possible to render specified area of GnomeCanvas in to pixmap and save it to file later
(Imlib or GdkPixbuf will help maybe)? I know printing/postscript generation will be handled by Gnomeprint in the future, but i only need a raw image file right now. My applications uses canvas to draw maps and I would like to see some kind of output, not screen image only :-).
