[pygtk] advice needed

[Gabriel]

Thanks; yes I use matplotlib for a lot of other things. But in this  
case I am not sure it is the best way to go. I have a huge pytables  
repository of relatively small and already calculated spectrograms  
(say 128x30 pixels) that I need to display, page after page. One  
screen can contain hundreds of them, so they need to be loaded  
relatively fast.

The thing is that I am new to pygtk (and gnome) and after reading  
various posts and articles, I am a bit confused about what the most  
straightforward way is to display many relatively small bitmaps on a  
canvas.

All best, Gabriel
