A method and device for zooming web pages

Abstract

The present invention provides a method and device for zooming web pages. When it is detected that the user performs a zoom-in or zoom-out operation on all or part of the presented webpage, the corresponding zoom-in or zoom-out operation is performed on the pre-acquired webpage pictures whose presented webpage content is greater than or equal to the content currently presented in the webpage , and present the zoomed-in or zoomed-out webpage picture to the user; and after the zoom-in or zoom-out operation ends, render the content that needs to be presented in the webpage determined based on the zoom-in or zoom-out operation, and render the rendered The content of the web page is replaced by the web page picture to be presented to the user. The present invention has the following advantages: by enlarging or reducing the pre-acquired pictures, the computer device does not need to constantly redraw the webpage based on the new webpage scaling ratio during the enlarging or shrinking process, greatly improving the webpage zooming speed and effectively reducing the occurrence of stuck possible.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for scaling webpages. Background technique [0002] In the prior art computer devices, especially in the prior art mobile terminals, the display screens for presenting webpages are relatively small, so in order to better browse the webpages, users often perform zoom-in and zoom-out operations on the webpages. However, in the process of webpage zooming, since the zooming ratio of the user's webpage often changes greatly, such as the user will enlarge the original webpage several times, etc., this will produce multiple gradual webpage zooming ratios in the webpage zooming process, for example, when When a user zooms in on a webpage, the scaling ratio of the webpage may gradually change to 1.5 times, 2 times, 2.5 times, etc. In order to ensure the integrity of the webpage during the zooming process, the computer device needs to calculate the zooming res...

However, in the process of webpage zooming, since the zooming ratio of the user's webpage often changes greatly, such as the user will enlarge the original webpage several times, etc., this will produce multiple gradual webpage zooming ratios in the webpage zooming process, for example, when When a user zooms in on a webpage, the scaling ratio of the webpage may gradually change to 1.5 times, 2 times, 2.5 times, etc. In order to ensure the integrity of the webpage during the zooming process, the computer device needs to calculate the zooming results of the webpage at each ratio and draw the webpage to Presented to the user, but because the zooming operation performed by the user is often a relatively fast process, for computer equipment, especially mobile terminals with low processing performance, often it has not yet completed the display of webpage zooming based on the zoom ratio of a webpage, A new webpage zoom ratio is obtained, which will cause the computer device to constantly discard the intermediate results generated during the webpage zooming process and frequently draw the webpage. This method consumes a lot of computing resources, resulting in slow webpage zooming and freezes
