[Tutor] get pixel color form canvas , or draw text on image (Tkinter lib).

[Yang]

    What I am trying to do is get the dot matrix
of chinese char, and then make  a font lib for embed system. 
    I had thought of print the char on a tk canvas,
and get dot color one bye one, but I found no mathod to get 
data form canvas.
    As for image, I can put and get dots on it, but I don't 
konw how to put a char on it!
    So, any ideas?  or should I consider using something like
gtk!
