Rolling and pagination display method and device for network dynamic picture

Abstract

The application discloses a rolling and pagination display method and a rolling and pagination display device for a network dynamic picture. The method comprises the steps of: downloading the network dynamic picture from a server to local by a picture access and download module; determining the valuing range of a visual area of a current webpage in real time according to the rolling value of a scroll bar by a visual area determining module; traversing the dynamic pictures downloaded to the local by a traversal processing module; aiming at each dynamic picture, judging whether the preset position of the dynamic picture is within the valuing range of the visual area; if yes, building a display label to display the corresponding picture; otherwise, not building the corresponding display label, and deleting the display label in the case that the corresponding display label is built; refreshing the webpage by a display module, and executing the display label to upload and display the corresponding picture.According to the rolling and pagination display method and device for the network dynamic picture, the rolling and pagination display of the dynamic picture can be achieved by rolling the scroll bar, the occupation of an internal storage and a GDI object can be reduced, and the processing efficiency of a client is improved.

Description

technical field [0001] The present application relates to the technical field of network information display processing, in particular to a method and device for scrolling and paging display of network dynamic pictures. Background technique [0002] There are a large number of dynamic pictures on the Internet at present. The most common dynamic picture is a Graphics Interchange Format (GIF, Graphics Interchange Format) picture. An important feature of a dynamic picture is that it can store multiple images in one file, and read out the data of multiple images stored in one file and display them on the screen one by one, thus loading and displaying the simplest animation , forming a dynamic effect. [0003] Clients, such as browsers or other clients that can browse web pages, need to access and browse a large number of dynamic pictures in some scenarios. For example, on the search result page of a dynamic picture search engine, a large number of dynamic pictures that meet th...

Problems solved by technology

For example, assuming that each page includes 18 dynamic pictures, after loading 12 pages, 198 dynamic pictures will be loaded and displayed on the current web page, and the occupied GDI objects can reach more than 4,000, while the usual client software only supports a few thousand Therefore, it will reduce the processing efficiency of the client used to browse the webpage, and may directly cause the client to crash when the performance of the local device is relatively backward.
