I need some advice about something I want to implement in one of my applications, Zooming.
Basically, I have a large picture that should act like a map (for example) and the user can only see part of it at one time, so I need to implement Zoom+Navigation.
I am not looking for code necessarily, but more ideas and how something like this should be implemented.
Short version: How does the concept of zooming and dragging works for maps?
Any idea is greatly appreciated.
