I haven't tried it myself but something like this might work:

1. get ChamplainView from the GtkChamplainEmbed widget by
gtk_champlain_embed_get_view()
2. As ChamplainView is a ClutterActor, you can create a texture from
it by  clutter_texture_new_from_actor()
3. Get the CoglTexture from ClutterTexture by clutter_texture_get_cogl_texture()
4. Get the image data by cogl_texture_get_data()
5. Use GdkPixbufLoader to load the data and save it with gdk_pixbuf_save()

I'm not sure at all this will work and I'm not sure this is the
easiest way either. If someone knows a better way, please let us know.

Cheers,

Jiri
