How to convert Gtk.Image to base64

Question

I have a Gtk.Image object and I want to convert it's data to a base64 encoded string (for use with imgur). How would I achieve that?

Answer 1

Has to run it through a gdk.pixbuf, but this seems the easiest:

import cStringIO
import base64

pixBuf = gtkImage.get_pixbuf()

fH = cStringIO.StringIO() 
pixBuf.save_to_callback(fH.write, "png") 
encodedBuffer = base64.b64encode(fH.getvalue()) #base64 encoded png
