Device, method and graphical user interface for zooming in on a touch-screen display

摘要

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.

主权项

1. A computer-implemented method, comprising:
at a device with a touch screen display: displaying a first portion of an electronic document; detecting a movement of an object on or near the touch screen display; in response to detecting the movement, translating the electronic document displayed on the touch screen display in a first direction to display a second portion of the electronic document, wherein the second portion is different from the first portion; in response to an edge of the electronic document being reached while translating the electronic document in the first direction while the object is still detected on or near the touch screen display:
displaying an area beyond the edge of the document, anddisplaying a third portion of the electronic document, wherein the third portion is smaller than the first portion; andin response to detecting that the object is no longer on or near the touch screen display, translating the electronic document in a second direction until the area beyond the edge of the electronic document is no longer displayed to display a fourth portion of the electronic document, wherein the fourth portion is different from the first portion.
