I don't think that you should hard code something like user interaction, 
just provide the methods for interaction such as:
zoom on reqion(x,y,w,h), user input could be dragging a rectangle
zoom to(here%), user input could be scrolling, ctrl scrolling or a input box
move view(x,y), user input could be scrolling, or holding MMB
