Abstract

Users can zoom in the pictures by double tap the screen or pinching with two fingers. But both of them have limitation. For double tap, it only allows a specific ratio to zoom in. If user wants to zoom to a precise area, it can't help. And for pinching with two fingers, user should operate so many times if the area is so tiny in a big size screen. There isn't a convenient way to zoom in precisely in one action.
