Electronic magazines have now entered the fourth generation, with HTML5 technology as existing independent of web sites. The electronic magazine has the characteristics of both a plane and the internet, and integrates interactive combination of images, characters, sounds, videos, games and the like to be presented to readers. In addition, the network elements such as hyperlinks, instant interaction and the like are provided, and the network elements are strong in ductility and can be transplanted to various personal terminals such as a PDA, a MOBILE, an MP4, a PSP and a TV (digital television, set top box) tablet personal computer for reading in the future. However, the Flash technology packages all the characters and pictures in the swf file, so that the search engine cannot record the contents of the electronic magazine at present. Therefore, the future electronic magazine does not use Flash, and the electronic magazine can be read across platforms through a browser directly, so that various mobile devices can see the electronic magazine of the original edition vector without obstacles, downloading and archiving are not needed, and the reading experience of the electronic magazine is greatly improved.
The core of an electronic magazine is an electronic document database. Electronic documents in the database carry various identifiers so that the documents can be easily retrieved from the database and then "reproduced" for display in a variety of ways according to different requirements. In contrast, the core of the printing plate is a "uniform" copy, and once printed, it is difficult to change its intended appearance by binding into a book. From a storage perspective, traditional printed magazines are kept around the world, on individual bookshelves or library shelves, subject to damage from time to time and repeated use. And the database of the electronic magazine is distributed in a limited one or several places for the subscribers to use through the network. Different readers can select different display modes, and the magazine edition can continuously modify and update the document according to the requirement. Daily updating and maintenance of databases and the processing of electronic documents are a very important link in the distribution of electronic magazines.
In the internet website group, a user needs a magazine reading experience that can realize a page turning effect in a browser, rather than a common scrolling reading mode from top to bottom in the browser. The magazine reading implementation technology using the page turning effect on the internet has an electronic magazine mode, and the mode needs to install a plug-in for electronic magazine reading in a client browser and then realizes the reading experience of the left and right page turning effect through the plug-in. In addition, other implementation modes exist on the internet, but the online reading processing of small files is realized, and the online reading processing of large files cannot be realized. Therefore, the internet website group platform needs to solve several important technical difficulties and problems:
1. how to let the user directly use the page turning experience effect without using a client plug-in;
2. if the PDF of the large file is read by turning the book online;
3. how fluency of large file PDF online page turning is realized;
4. how timely the online reading of the file is realized;
5. how files are integrated and orderly organized together after being split into pictures.
The five problems are all practical technical problems which need to be solved by the Internet website group platform. The internet website group platform is a station building platform and a propaganda platform of an enterprise facing to the whole internet environment, when magazines are provided for reading, website visitors cannot be required to install plug-ins forcibly, firstly, the security cannot be guaranteed well, and most importantly, the website visitors can generate conflict psychology in mind.

Detailed Description
The present invention is further described below, and the following examples are only used to more clearly illustrate the technical solutions of the present invention, but not to limit the scope of the present invention.
The invention discloses an online friendly reading picture segmentation method for Internet station group magazine files, which comprises the following steps:
firstly, storing PDF files uploaded by website management users in a background, wherein the storage method comprises the steps of firstly, using organization code (orgCode) to which the users belong as a first-layer directory, establishing a category directory according to PDF file categories (Catalog) under the directory, simultaneously establishing subfolders under the category directory according to dates (yyyy-MM-dd) for distinguishing and separating files uploaded on different dates, and storing the uploaded PDF files in the corresponding subfolders. The entire file structure after the above storage processing is shown in fig. 1.
And secondly, the stored magazine file structure address is recorded in a Urlpath field of a platform database of the Internet website group, after the uploading action of a user is finished, a background of the Internet website group automatically generates a task message, the task message comprises field information of an organization code orgCode, a message creator code userId, a service module code serviceCode, message creation time createTime, a magazine source file address pdfPath and a processed magazine address finalPdfPath, the task message is sent to a message queue server of the Internet website group, and the message queue server stores task messages corresponding to magazines uploaded by all the users. In the field information, the rest fields except the finalPdfPath field are filled with values by a website group background, the service module codes serviceCode marks the database record of a certain magazine under the current organization in the website group platform system and the mapping of the magazine source file, and the magazine source file can be found through the serviceCode. The pdfPath is transmitted to the message queue server by the web cluster system and has the same value as the UrlPath. The finalddfpath is a new address after online friendly reading processing of the source magazine file, and the value is set by the message queue server. The task message storage structure in the message queue is shown in fig. 2, and the message ID in fig. 2 is automatically generated by the message queue server, and the web site group platform system does not intervene.
And thirdly, the task message in the message queue server consumes and processes the message according to the FIFO principle, namely, the task message is processed first when the task message comes first. The message queue server creates a separate thread for each task message to process, and once the thread is successfully started, the corresponding task message in the message queue server is removed.
The processing procedure of each thread is shown in fig. 3: reading a task message, extracting a magazine source file address pdfPath from the task message, downloading the magazine source file into a temporary directory TMP, naming the magazine source file as TMP _ magazine source file name, judging whether the size of the magazine source file exceeds a preset threshold (such as 50M) of an item or not by a first page, and if the size of the magazine source file exceeds the preset threshold, turning to the fourth step; otherwise, the website group message queue decomposes and converts the pdf magazine source file into pictures by adopting an icepdf tool, the converted picture number PICCount is the same as the page number of the pdf magazine source file, and the naming rule of the pictures is as follows: the names of the head and tail cover pictures are as follows: a magazine source file name _ index and a magazine source file name _ end, the intermediate pictures are named as: magazine source file name page number. The conversion speed of 50M pdf magazine source files into pictures is very fast, and the conversion can be completed within almost 3 s. And after the pictures are converted, organizing the generated pictures together by adopting a jFlip plug-in to form a final magazine page turning effect file package, wherein files in the file package comprise js, css, images and html, and the html is index. After the final file package is formed, the message queue server pushes the file package to a file directory structure in the first step, a directory with the same name as the magazine source file is created in the last magazine source file directory layer, namely a subfolder layer established according to the date (yyyy-MM-dd), then the file package is placed under the directory, finally the field value of the processed magazine address finalddpath is set as the file package address pushed by the message queue server, and the task message with the updated finalddpath value is sent back to a website group management background for updating and storing.
Fourthly, referring to fig. 3, when the magazine source file size exceeds the preset threshold, the web site group message queue server will use the iText technique to cut the pdf magazine source file of the large file into files with different numbers according to the threshold size, where the number of the cut files is equal to the magazine source file size divided by the threshold, and the divided files are individually used as one file. The cut files are temporarily stored under a TMP _ magazine source file name _ split directory path, and the small cut files are named as: magazine source file name _01, magazine source file name _02, magazine source file name _03 … …, and so on. And then, converting the pictures of the divided small files by adopting an icepdf tool according to the operation mode of the third step, wherein after the conversion of the pictures of each small file is finished, the converted pictures are combined and integrated according to the sequence of the small files. And after the integration is finished, organizing the generated pictures together by adopting a jFlip plug-in according to the operation mode of the third step to form a final magazine page turning effect file package.
The combination here is divided into two processes: firstly, combining the converted pictures of each small file according to the file names and page number serial numbers of the pictures; and then all the small files are combined again according to the file names and the page number serial numbers of the pictures.
And fifthly, in the processing processes of the third step and the fourth step, if any link has a problem, the task message execution is interrupted, the task message is added into a network station group REDO message queue, the message queue and the message queue in the third step are separately and independently operated, the task execution processes in the message queue and the message queue in the third step are the same, when one task message REDO operation exceeds three times, the task message is discarded and is not continuously executed, and the result is fed back to a network station group background to prompt a user to upload the operation again.
The task information enters into the REDO and can be immediately restarted to be executed, the information added into the REDO does not influence the execution of the original task in the message queue server, and the REDO and the message queue server execute in parallel.
Sixthly, when a website visitor opens a magazine link for browsing, the processed magazine address finalddfpath is directly presented in the browser, html is visited by default, and at this time, magazine reading with page turning effect can be experienced.
The algorithm uses the segmentation model to segment PDF files uploaded by website management users in the background, the segmented sizes are determined in different configuration modes, then the corresponding PDF files are segmented into small blocks with different numbers according to the determined sizes, and then the small blocks are subjected to picture conversion.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
