1. A device, comprising:
- a touch screen display;
one or more processors;
memory; and
one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for;
displaying at least a first portion of an electronic document at a first magnification;
detecting a gesture on the touch screen display corresponding to a command to zoom in by a user-specified amount;
displaying decreasing portions of the electronic document at increasing magnifications, in response to detecting the gesture;
detecting termination of the gesture;
detecting that a displayed magnification of the electronic document exceeds a predefined magnification upon detecting termination of the gesture; and
in response to detecting termination of the gesture and detecting that the displayed magnification of the electronic document exceeds the predefined magnification upon detecting termination of the gesture, displaying a respective portion of the electronic document at the predefined magnification, greater than the first magnification.

Abstract
In accordance with some embodiments, a computer-implemented method for use in conjunction with a device with a touch screen display is disclosed. In the method, at least a first portion of an electronic document is displayed at a first magnification. A gesture is detected on or near the touch screen display corresponding to a command to zoom in by a user-specified amount. In response to detecting the gesture, decreasing portions of the electronic document are displayed at increasing magnifications. If, upon detecting termination of the gesture, the magnification exceeds a predefined magnification, a respective portion of the electronic document is displayed at the predefined magnification.

14. A non-transitory computer readable storage medium having stored therein instructions, which when executed by a device with a touch screen display, cause the device to:
-
display at least a first portion of an electronic document at a first magnification; detect a gesture on the touch screen display corresponding to a command to zoom in by a user-specified amount; display decreasing portions of the electronic document at increasing magnifications, in response to detecting the gesture; detect termination of the gesture; detect that a displayed magnification of the electronic document exceeds a predefined magnification upon detecting termination of the gesture; and in response to detecting termination of the gesture and detecting that the displayed magnification of the electronic document exceeds the predefined magnification upon detecting termination of the gesture, display a respective portion of the electronic document at the predefined magnification, greater than the first magnification. - View Dependent Claims (15, 16, 17)
