std::string image_pixels (reinterpret_cast<const char
*>(ref_orig->get_pixels()), ref_orig->get_rowstride());
Did you mean ref_orig->get_rowstride() * ref_orig->get_height() ?
Glib::RefPtr<Gdk::Pixbuf> ref_dest = Gdk::Pixbuf::create_from_data (
reinterpret_cast<const guint8*>(image_pixels.c_str()),
Gdk::COLORSPACE_RGB, ref_orig->get_has_alpha(),
ref_orig->get_bits_per_sample(), ....);
std::string::c_str() copies the data in a new null terminated buffer, so
this cannot work if your image contains null bytes. Maybe
std::string::raw() will do the trick, but I advise to investigate
another way of storing your pixels.
