Loading method of format data flow file

Abstract

The invention provides a format data flow file loading mode. A format data flow file is stored in a server. The server cuts the format data flow file into a plurality of independent files. Each independent file contains a code and a page number. A method for loading the format data flow file to a device terminal comprises the steps of creating an association array, wherein the association array contains file sequence association and file page number association, wherein the file sequence association is obtained by the independent files according to code sorting, and the file page number association is obtained by the corresponding independent file page numbers in the file sequence association; calculating a page number sum of the independent files, performing rendering by the device terminal to obtain a file frame, and performing downloading by multiple threads to obtain the format data flow file; and according to the page number of the current page of the format data flow file, obtaining the corresponding independent file page number, calculating the page numbers of first P pages and last Q pages of the page, and performing rendering by the device terminal. According to the loading mode, the file loading speed can be increased, and the format data flow file can be viewed without waiting until the format data flow file is completely downloaded, so that the synthesis step of the server is removed and the running burden is reduced.

Description

technical field [0001] The invention relates to the technical field of creation, storage and transmission of electronic files, in particular to a method for loading format data flow files. Background technique [0002] In the prior art, when the server loads the layout data stream file, it first needs to synthesize the form, body, attachment and other independent files in the layout data stream file, and then render the synthesized file after downloading, thus synthesizing The process increases the burden on the server. In addition, when the layout data flow file is too large and the network is too poor, it is easy to cause the file to fail to open, or the waiting time is long, which greatly affects the user experience and use effect. Sometimes, users only need to check the approval documents in the layout data flow file, and do not need to check other information. At this time, because the layout data flow file has not been downloaded, it is impossible to view the approval ...
