And, the generated picture is in-line font supporting PDF.
Specifically, in order to parse and slice PDF files more efficiently and quickly, the server uses JDk thread pools; the server divides the PDF file into small files by using an JDk thread pool, and then divides the small files into a plurality of pictures; the server may then perform a scaling process on each picture. Therefore, the method can meet the requirement of certain precision of the picture, reduce memory overhead and memory occupation, and further reduce the overflow of the memory occupation.
Then, the server configures a picture path for each picture, so as to obtain a segmented PDF file, wherein the segmented PDF file comprises the picture, the identification of the PDF chapter, the picture path, and the corresponding relationship between the identification of the PDF chapter and the picture path. Wherein, the picture path is a URL.
Step 302, storing the picture path and the corresponding relationship between the identifier of the PDF chapter and the picture path in an electronic document buffer.
In this embodiment, specifically, the server stores the obtained picture path and the correspondence between the identifier of the PDF chapter and the picture path in the electronic document buffer.
Moreover, the server can perform multiple cache packaging on the obtained picture path, further realize page level cache by using the oscache, cache a single file and cache the URL Pattern, and set the cache attribute. Furthermore, the time-consuming problem of loading the generated pictures and PDF files on the server is reduced; the server may be capable of caching any Uniform Resource Identifier (URI) through the cache filtering function of servlet 2.3. And moreover, the Jgroups are integrated to realize cached clusters, so that the files in the electronic cache can be acquired more quickly.
Step 303, receiving a second reading request sent by the terminal, where the second reading request includes an identifier of a chapter to be read of the PDF file.
In this embodiment, specifically, the server receives a second reading request sent by the terminal, where the second reading request includes a type of a file to be read, an identifier of the file to be read, and an identifier of a reading section of the file to be read; and the server can determine the file to be read corresponding to the file to be read identifier.
Then, when the type of the file to be read is a file in the PDF format, the server may determine the identifier of the reading section of the file to be read, which is the identifier of the section of the PDF file to be read.
And step 304, determining a picture path corresponding to the identification of the to-be-read section of the PDF file according to the electronic document buffer, wherein the electronic document buffer also comprises the corresponding relation between the identification of the PDF section and the picture path.
In this embodiment, specifically, because the electronic document buffer has a correspondence between the identifier of the PDF chapter and the picture path, the server may determine the picture path corresponding to the identifier of the chapter to be read of the current PDF file.
And 305, determining a picture corresponding to the picture path according to the corresponding relation between the preset picture path and the picture.
In this embodiment, specifically, the server stores a corresponding relationship between the picture path and the picture, and the server can determine the picture corresponding to the picture path.
And step 306, sending the picture corresponding to the picture path to the terminal so that the terminal displays the picture corresponding to the picture path on the webpage.
In this embodiment, specifically, the server sends the determined picture to the terminal. When the pictures are transmitted between the server and the terminal, the pictures are transmitted by adopting an HTTP (hyper text transport protocol).
The terminal may then display the received picture on a web page. Moreover, the terminal can receive an adding request sent by a user, wherein the adding request comprises adding content; the terminal adds the added content to the displayed picture. And further, the functions of adding annotations, bookmarks and the like with the user are completed.
The server performs picture segmentation on the PDF file through the steps, the PDF file is segmented into a plurality of pictures, and the pictures are zoomed; the server sends the picture corresponding to the reading chapter of the PDF file to the terminal; the terminal displays the picture on the webpage; the terminal does not need to process the PDF type file, and the PDF type file can be directly displayed, so that the user can conveniently read the PDF type file on line.
