I have never tried this, but instead of messing with create_from_data,
I would do something like this:

  Glib::RefPtr<Gdk::Pixbuf> pixbuf = Gdk::Pixbuf::create(...);
  pixbuf->fill(0xFFFFFF);

Then there are some methods in Gdk::Pixbuf to retrieve a pointer to
the data and help navigating the pixels.
