yes ,I have already skip through the API of gdk-pixbuf. And there I found some
functions that I need, like: width, eight, access to actual pixels,
etc...but I was wondering if for example in the case of PGN, would be
better to use gdk-pixbuf or libpng? gdk-pixbuf use libpng as far as I know.

Basically the image classification system wil have (for this very beginning):

- Preprocessing unit (remove noise, edge enhancement (Shen-Castan edge
  detector, any better choice)).

- Classificator (based on a "Self Organized Map"and a "Backpropagation Network")

So, I need access to the atributtes I  talked above, so I can implement
the algorithms I have just mention. ALso I'm wondering how fast those
algorithms can be.

Thanks.
