Hi,
As a complement to scale, that allways scales a diagram to the sepcified width*height, I would request a command maxsize width*height that would scale down the diagram to fit if needed, but if the diagram already is smaller than this bounding box it would never attempt at scaling up the image.
This would be very useful to keep diagram images within sertain boundaries - and if they become too small the user would have to divide the diagram. May not work together with page splitting though..
Br,
Peter
