ELECTRONIC DEVICE AND PAGE ZOOMING METHOD THEREOF

摘要

A page zooming method for an electronic device includes, firstly, generating operation signals in response to a touch operation applied on a page displayed on a touch screen of the electronic device. Secondly, one touch operation is determined to be a zoom-triggering gesture when a duration of time of pressing the touch screen on one touching point is longer than a first preset duration of time. Thirdly, one slide operation is identified according to the operation signals generated by the touch screen in response to the slide operation. Next, a zooming type and a zooming ratio are determined according to the zoom-triggering gesture and the slide operation. Lastly, the page is zoomed according to the zooming type and zooming ratio. An electronic device using the page zooming method is also provided.
