At a guess: the inflation (or, in this case, deflation) is centred on the centre of the figure. So a horizontal change of -50 means the left edge moves 25 pixels right and the right edge moves 25 pixels left. (or, rather, the total width drops frrom 70 pixels to 20 pixels) I'm not sure what's going on with the height, though. -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
