title: Python PyGObject Get pixel from GdkPixbuf.get_pixels()
body: <p>I've written a python program using GTK+2 (pygtk). Now I want to update the program to GTK+3, so I have to use pyGObject instead of pygtk.<br>
  My problem is, that I have to get the color from individual pixels on a GdkPixbuf.Pixbuf object.<br>
  In pygtk i could just use Pixbuf.get_pixels_array() to get a n array containing all the pixels.<br>
  In pyGObject there is no Pixbuf.get_pixels_array(), so I have to use Pixbuf.get_pixels(), which returns me a string.<br>
  Does anyone know how to get individual pixels from this string?<br>
  <br>
  (In C Pixbuf.get_pixels_array() returns a pointer, so you can do this: <a href="http://developer.gimp.org/api/2.0/gdk-pixbuf/gdk-pixbuf-gdk-pixbuf.html#image-data" rel="nofollow">http://developer.gimp.org/api/2.0/gdk-pixbuf/gdk-pixbuf-gdk-pixbuf.html#image-data</a> , but in python it returns a string)<br>
  <br>
  Thanks for helping.</p>
