[0041] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0042] Embodiment 1

[0043] Figure 1 The flowchart of a method for processing local files in an e-book client provided by the first embodiment of the present invention is shown. The processing method provided by this embodiment can be executed by a file processing plug-in client in the e-book client.

[0044] like Figure 1 As shown, the method comprises the following steps:

[0045] Step S110, obtaining the electronic book format file according to the file information of the electronic book format file sent by the host program client.

[0046] The user can import the corresponding local file through the local file import entry provided by the host program client of the e-book client. The local file may include an e-book format file and a media format file. Among them, the e-book format file is specifically a PDF file; the media format file may include at least one of the following files: a picture file, an audio file, and a video file. The embodiment of the present invention will perform subsequent optimization processing on the local file of the e-book format file.

[0047] Specifically, before displaying the locally imported e-book format file, the host program client needs to send the file information of the e-book format file to the file processing plug-in client. The file processing plug-in client obtains the e-book format file according to the file information of the e-book format file sent by the host program client.

[0048] In an optional implementation, the file information of the e-book format file sent by the host program client may be the e-book format file itself, so that the file processing plug-in client directly performs subsequent parsing operations according to the received e-book format file.

[0049] In another optional implementation, the file information of the e-book format file is specifically the storage path of the e-book format file, and the file processing plug-in client loads the e-book format file from the storage location corresponding to the storage path. This method can save transmission costs and improve the efficiency of obtaining e-book format files.

[0050] Step S120, parsing the electronic book format file to obtain a parsing result.

[0051] For e-book format files that cannot be directly displayed by the host program client, the embodiment of the present invention generates corresponding images by parsing such e-book format files through the file processing plug-in client, and provides the generated images for the host program client to display, thereby realizing the display of such e-book format files in the host program client without jumping to a third-party application and without the need for front-end personnel to compile web pages.

[0052] In an optional embodiment, at least one code package corresponding to an e-book format is integrated in the file processing plug-in client, and the code packages corresponding to different e-book formats are different. When parsing an e-book format file, the file processing plug-in client specifically determines the e-book format to which the e-book format file belongs, and calls the code package corresponding to the e-book format to parse the e-book format file. For example, an SO package is generated in advance by compiling a PDF source code library, and the SO package is integrated into the file processing plug-in client. When the e-book format file is a PDF file, the SO package corresponding to the PDF is called to parse the e-book format file. In this way, not only can e-book format files of different e-book formats be parsed, but also the parsing process of e-book format files of different e-book formats is decoupled, thereby improving the scalability of the file processing plug-in client.

[0053] Step S130, determining a plurality of page blocks into which the display page is divided according to the page segmentation parameters.

[0054] After obtaining the parsing result of the e-book format file in step S120, if the corresponding page image is directly generated (one page image corresponds to a display page, and the page image is consistent with the display page size), when the page image occupies a large space or the processing power of the electronic device is weak, the host program client directly loads the entire page image, resulting in memory overflow or thread jamming, thereby causing the page image loading failure or loading time being too long.

[0055] To avoid the technical drawbacks, the embodiment of the present invention further performs segmentation processing on the display page, and segments the display page into multiple page blocks. A block image corresponding to each page block is generated, so that the host program client loads the block image as a loading unit, thereby avoiding the drawbacks of thread jamming and memory overflow.

[0056] It should be understood that the segmentation of the display page in the embodiment of the present invention is not equivalent to the paging processing of the electronic book format file. The embodiment of the present invention is to segment a display page in an electronic device into multiple page blocks, and the multiple page blocks constitute a complete display page. The paging processing of the electronic book format file is to split the electronic format file into multiple pages, each page corresponding to a display page.

[0057] Specifically, when splitting the display page, the multiple page blocks included in the display page are determined according to the page segmentation parameters, wherein the page segmentation parameters may include the number of page blocks of the display page, the size of the page blocks and / or the page segmentation method, etc.

[0058] In an optional implementation, in order to ensure the accuracy of the display page segmentation result, the page size parameter sent by the host program client may be further received, and the multiple page blocks contained in the display page may be determined according to the page segmentation parameter and the page size parameter. For example, the page segmentation parameter may be "page segmentation method: 8*4", and the page size parameter may be "1080*1920", then the display page may be segmented in a segmentation method of 8 rows and 4 columns to obtain 32 page blocks of size "270*240".

[0059] In another optional implementation, the electronic device processing capacity parameter can be obtained, and the page segmentation parameter can be determined according to the electronic device processing capacity parameter. Among them, the number of page blocks contained in the display page after division is negatively correlated with the electronic device processing capacity, that is, the stronger the electronic device processing capacity, the fewer the number of page blocks contained in the display page after division. In this way, the number of page blocks of the display page can be adapted to the processing capacity of the electronic device, and the number of page blocks contained in the display page can be reduced while ensuring that memory overflow and thread jams are avoided, thereby improving the overall execution efficiency of the method.

[0060] Step S140: generating a block image corresponding to each page block based on the analysis result.

[0061] According to the analysis result, the e-book format file can be converted into a picture. The embodiment of the present invention does not limit the specific format of the picture, for example, the converted picture can be in jpg, png, webp and other formats. Specifically, for each page block in the display page, a block picture corresponding to each page block is generated, that is, one page block corresponds to one block picture.

[0062] Step S150 , transmitting the generated block images to the host program client, so that the host program client can generate a display page according to the block images corresponding to each page block.

[0063] The host program client loads the images in units of block images, and finally generates a complete display page according to the block images corresponding to each page block in the display page.

[0064] It can be seen that the present embodiment parses and processes the e-book format files that cannot be directly displayed by the host program client of the e-book client, and obtains the block image corresponding to the display page according to the parsing result, so as to display the block image in the host program client, thereby realizing the display of the e-book format files in the e-book client without jumping to a third-party application, improving the user experience, and improving the display efficiency of local files in the e-book client; and, the present embodiment splits the display page into multiple page blocks according to the page segmentation parameters, generates the block image corresponding to each page block, and loads them in units of block images, avoiding the phenomenon of memory overflow and thread jamming, and further improving the display efficiency of local files in the e-book client.

[0065] Embodiment 2

[0066] Figure 2 The flowchart of a method for processing local files in an e-book client provided by the second embodiment of the present invention is shown. The processing method provided by this embodiment can be executed by a file processing plug-in client in the e-book client.

[0067] like Figure 2 As shown, the method comprises the following steps:

[0068] Step S210, acquiring the electronic book format file according to the file information of the electronic book format file sent by the host program client, and parsing the electronic book format file to obtain a parsing result.

[0069] Step S220: generating a global image corresponding to the display page based on the analysis result, and transmitting the generated global image to the host program client.

[0070] Among them, the global image is consistent with the display page size, and the resolution of the global image is smaller than the resolution of the block image. Due to the low resolution of the global image, the host program client is not prone to memory overflow and thread jamming when loading the global image. Passing the global image with a lower resolution to the host program client allows the host program client to display the display page generated based on the global image when the block image fails to load, thereby avoiding the situation where the user cannot view the electronic format file and improving the user experience.

[0071] In a specific implementation, the host program client pre-creates a blank bitmap corresponding to the display page, the blank bitmap is consistent with the size of the display page, and sends the blank bitmap to the file processing plug-in client. The file processing plug-in client receives the blank bitmap corresponding to the display page sent by the host program client, renders the global image in the blank bitmap to generate a global bitmap, and transmits the generated global bitmap to the host program client.

[0072] Step S230, determining a plurality of page blocks into which the display page is divided according to the page segmentation parameters, generating a block image corresponding to each page block based on the analysis result, and transmitting the generated block image to the host program client.

[0073] Among them, step S220 and step S230 can be executed sequentially or concurrently.

[0074] It can be seen that in addition to generating block images corresponding to page blocks, this embodiment further generates a global image corresponding to the display page, and transmits the generated global image to the host program client, so that the host program client can display the display page generated based on the global image when the block image fails to be loaded, thereby avoiding the situation where the user cannot view the e-book format file and improving the user experience.

[0075] Embodiment 3

[0076] Figure 3 The flowchart of a method for displaying local files in an e-book client provided by the third embodiment of the present invention is shown. The processing method provided by this embodiment can be executed by a host program client in the e-book client.

[0077] like Figure 3 As shown, the method comprises the following steps:

[0078] Step S310: sending the file information of the electronic book format file to the file processing plug-in client, so that the file processing plug-in client can obtain the electronic book format file according to the file information.

[0079] The host program client determines the e-book format file corresponding to the user's viewing operation of the e-book format file in response to the user's viewing operation, then initializes the file processing plug-in client, and sends the file information of the e-book format file corresponding to the viewing operation to the file processing plug-in client. Optionally, the file information of the e-book format file can be a storage path of the e-book format file.

[0080] Step S320, obtaining a block image generated by the file processing plug-in client according to the parsing result of the e-book format file.

[0081] After the host program client sends the file information of the e-book format file to the file processing plug-in client, the file processing plug-in client obtains the e-book format file according to the file information, and parses the e-book format file to obtain the parsing result. And according to the page segmentation parameters, it determines the multiple page blocks divided into the display page, and generates the block images corresponding to each page block. That is, each block image corresponds to a page block, and a display page is divided into multiple page blocks.

[0082] Each time the file processing plug-in client generates a block image, the host program client obtains the generated block image.

[0083] Step S330 , generating a display page according to the block images corresponding to each page block.

[0084] The host program client integrates all the block images corresponding to the loaded display page to generate a display page, and displays the display page.

[0085] It can be seen that this embodiment converts the e-book format file into an image, so that the e-book format file can be displayed in the e-book client without jumping to a third-party application, thereby improving the user experience and improving the display efficiency of local files in the e-book client; and, this embodiment loads the image in units of block images, avoiding memory overflow and thread jamming, and further improving the display efficiency of local files in the e-book client.

[0086] Embodiment 4

[0087] Figure 4 The flowchart of a method for displaying local files in an e-book client provided by the fourth embodiment of the present invention is shown. The processing method provided by this embodiment can be executed by a host program client in the e-book client.

[0088] like Figure 4 As shown, the method comprises the following steps:

[0089] Step S410: sending the file information of the electronic book format file to the file processing plug-in client.

[0090] In an optional implementation, after sending the file information of the e-book format file to the file processing plug-in client, the host program client creates a corresponding thread to monitor the processing dynamics of the file processing plug-in client.

[0091] Step S420: obtaining, through the first execution queue, a block image generated by the file processing plug-in client according to the parsing result of the e-book format file.

[0092] The host program client creates a first execution queue, and after monitoring that the file processing plug-in client generates a block image, obtains the generated block image through the first execution queue.

[0093] Step S430: Acquire the global picture generated by the file processing plug-in client through the second execution queue.

[0094] Specifically, after monitoring the file processing plug-in client parsing the e-book format file, the host program client sets the relevant parameters of the display page, including: zoom ratio, page number, horizontal and vertical version attributes, etc., and generates a blank bitmap corresponding to the display page number, and sends the blank bitmap to the file processing plug-in client.

[0095] The file processing plug-in client generates a global image based on the parsing result of the e-book format file, and renders the global image in a blank bitmap to generate a global bitmap. The resolution of the global image is smaller than the resolution of the block image, and the size of the global image is consistent with the display page size. The global bitmap is further loaded through the second execution queue created by the host program client, thereby obtaining the global image generated by the file processing plug-in client.

[0096] Step S440, determine whether there is a block image loading failure; if so, execute step S450; otherwise, execute step S460.

[0097] Specifically, if a block image loading error message is received, or if all block images corresponding to the display page cannot be received within a preset time, it is determined that a block image loading failure exists, and step S450 is executed; otherwise, step S460 is executed.

[0098] Step S450, generating a display page according to the global image, and displaying the display page.

[0099] If it is determined that the block image fails to load, a display page is generated according to the global image, and the global image is displayed to the user, thereby avoiding the disadvantage that the e-book format file cannot be viewed.

[0100] Step S460 , generating a display page according to the position parameters of each page block and the block images corresponding to each page block.

[0101] Specifically, the host program client records the position parameters of each page block. If the page block is a rectangle, the position parameters of the page block include the position coordinates of a pair of diagonal vertices in the rectangle. According to the position parameters of each page block, the block image corresponding to the page block can be displayed in the page position corresponding to the position parameter, thereby improving the display accuracy of the displayed page.

[0102] In addition, in an optional implementation, after obtaining the global image, the host program client draws the global image on the bottom layer of the page of the host program client; and sets another layer on the bottom layer of the page, and draws the block image in the other layer after each block image is obtained. If it is determined that there is a block image loading failure, the attribute of the other layer is set to transparent, or the other layer is deleted to quickly display the display page composed of the global image; if it is determined that there is no block image loading failure, all the block images in the other layer completely cover the layer where the global image is located, so as to display the display page composed of the block images.

[0103] In another optional implementation, after the global image is acquired and before all the block images corresponding to the display page are acquired, the global image can be displayed to generate a display page, so that the user can preview the e-book format file based on the low-resolution global image to improve the user experience. After all the block images corresponding to the display page are successfully acquired, the display page composed of the block images is displayed.

[0104] It can be seen that, when it is determined that there is a block image loading failure, the embodiment of the present invention displays a display page generated according to the global image, thereby avoiding the situation where the user cannot view the e-book format file, thereby improving the user experience; and in the embodiment of the present invention, the acquisition of block images and global images is executed through different execution queues, which on the one hand improves the image loading efficiency, and on the other hand isolates the global image acquisition process from the block image acquisition process to avoid mutual interference and improve loading accuracy.

[0106] Figure 5 A schematic diagram of information interaction between a host program client and a file processing plug-in client provided in a fifth embodiment of the present invention is shown.

[0107] Specifically,

[0108] Step S510: the host program client sends the file information of the electronic book format file to the file processing plug-in client.

[0109] Step S520: the file processing plug-in client obtains the e-book format file according to the file information of the e-book format file sent by the host program client.

[0110] Step S530, the file processing plug-in client parses the e-book format file to obtain a parsing result; determines a plurality of page blocks into which the display page is divided according to the page segmentation parameter, and generates a block image corresponding to each page block based on the parsing result.

[0111] Step S540: the host program client loads the block image.

[0112] Step S550 : the host program client generates a display page according to the block images corresponding to each page block.
