EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the form (henceforth, embodiment) for implementing this invention is demonstrated in detail. In subsequent figures, the same numbers or symbols are attached to the same elements throughout the description of the embodiments.

[Basic Concept/Basic Configuration]
FIG. 1 is a diagram for explaining an overview of a viewing PDF generation system 1. As shown in FIG. The viewing PDF generation system 1 is a system that generates a viewing PDF on a cloud server that provides cloud services. In the present invention, PDF is a data file in Portable Document Format. Also, embedded PDF refers to separate PDF data embedded in PDF data. The viewing PDF generation system 1 is a system that includes at least a cloud server 100 that controls the viewing PDF generation system 1 and a user terminal 200 of the user 2 that creates and views the PDF. Although not shown in FIG. 1, the cloud server 100 and the user terminal 200 are assumed to be able to communicate via the network 3 . Also, it is assumed that a plurality of users 2 and user terminals 200 may exist. FIG. 1 shows user 2A and its user terminal 200A, and user 2B and its user terminal 200B. The cloud server 100 refers to a cloud computer, and may be realized by a plurality of computers instead of one computer. A cloud computer in this specification is a computer that uses any computer in a scalable manner to perform a specific function, or includes multiple functional configurations to realize a certain system, and uses the functions in a free combination. It can be anything. It is assumed that user 2 participates in the cloud service.

First, the extraction unit 101 of the cloud server 100 extracts at least another embedded PDF and rendering data from the PDF (step S01). The PDF may be already saved in the cloud server 100, or may be obtained from the user 2A via the user terminal 200A. When it is obtained from the user terminal 200A, it may be created by the user 2A himself or may be obtained by the user 2A from another person or the like. PDF may also include embedded PDF. Here, embedded PDF is another PDF data embedded in PDF data. If the embedded PDF does not exist, there is no need to extract it. Here, rendering data refers to data necessary for rendering, such as font data and codecs. Rendering data is also extracted from the embedded PDF. The example in FIG. 1 shows an example in which an embedded PDF (File X), font data (Font A) as rendering data, and codec (Codec A) are extracted from a PDF. Font data (Font B) and codec (Codec B) are also extracted from the embedded PDF (File X) as rendering data. If the embedded PDF (File X) further includes an embedded PDF, its rendering data is also extracted.

Next, the storage unit 102 of the cloud server 100 stores at least the PDF, the embedded PDF, and the extracted rendering data in the cloud server 100 (step S02). If the PDF does not contain an embedded PDF, it need not be stored.

Next, the generation unit 103 of the cloud server 100 creates a link based on the stored PDF, embedded PDF, and rendering data, and generates a viewing PDF (step S03). The link created here is for accessing the PDF, embedded PDF, and rendering data stored in the cloud server 100 .

Finally, the provision unit 104 of the cloud server 100 provides the generated PDF for viewing to the user 2B via the user terminal 200B (step S04). As a method for displaying the viewing PDF on the user terminal 200B, the viewing PDF generation system 1 may include a WEB viewer. The WEB viewer refers to the links of the stored PDF, the embedded PDF, and the rendering data, acquires necessary information from the referenced links, and outputs the viewing PDF to the user terminal 200B. and

In the example of FIG. 1, even if the user terminal 200A includes Font A and the user terminal 200B does not include Font A, the user terminal 200B can refer to the rendering data of the viewing PDF. But it is possible to display the correct PDF. Also, at that time, there is no need to install Font A on the user terminal 200B. Since Font A is not embedded as data in the PDF for viewing, and only link information is included, there is no need to transmit or receive extra data. Also, by storing rendering data such as font data only on the cloud server side and not storing it on individual user terminals 200, it is possible to reduce the data size on the user terminal 200 side.

As described above, according to the present invention, it is possible to provide a browsing PDF generation system that allows the original PDF to be browsed without depending on the environment of the user terminal 200 . As a result, it is possible to obtain the advantage that the data size of the user terminal 200 can be suppressed and that unnecessary rendering data need not be added to the user terminal 200 .

The user terminal 200 also includes various devices and the like that execute various processes as a processing unit (not shown).

[PDF generation process for browsing]
Based on FIG. 3, the viewing PDF generation processing executed by the cloud server 100 will be described. FIG. 3 is a flow chart showing viewing PDF generation processing executed by the viewing PDF generation system 1. As shown in FIG. Processing executed by each unit described above will be described together with this processing.

First, the extraction unit 101 of the cloud server 100 extracts at least another embedded PDF and rendering data from the PDF (step S301). The PDF may be already saved in the cloud server 100 or may be obtained from the user 2 via the user terminal 200 . When the PDF is obtained from the user terminal 200, the PDF may be created by the user 2 himself or may be obtained by the user 2 from another person or the like. PDF may also include embedded PDF. If the embedded PDF does not exist, there is no need to extract it. Here, rendering data refers to data necessary for rendering, such as font data and codecs. Rendering data is also extracted from the embedded PDF. If the extracted embedded PDF further includes an embedded PDF, its rendering data is also extracted.

Next, the storage unit 102 of the cloud server 100 stores at least the PDF, the embedded PDF, and the extracted rendering data in the cloud server 100 (step S302). If the PDF does not contain an embedded PDF, it need not be stored.

Next, the generation unit 103 of the cloud server 100 creates a link based on the stored PDF, embedded PDF, and rendering data, and generates a viewing PDF (step S303). The link created here is for accessing the PDF, embedded PDF, and rendering data stored in the cloud server 100 .

Finally, the provision unit 104 of the cloud server 100 provides the generated PDF for viewing to the user 2 via the user terminal 200 (step S304). As a method for displaying the PDF for viewing on the user terminal 200, the PDF for viewing generation system 1 may include a WEB viewer. The WEB viewer refers to the links of the stored PDF, the embedded PDF, and the rendering data, acquires necessary information from the referenced links, and outputs the viewing PDF to the user terminal 200. and

Here, the user terminal 200 that provides the PDF for viewing in step S304 may or may not include font data, codec, etc., which are data for rendering, to render the PDF for viewing at the link destination. It is possible to display the correct PDF by referring to the data. In addition, font data, codecs, etc. are not embedded as data in the PDF for viewing, and only link information is included. Also, by storing rendering data such as font data only on the cloud server side and not storing it on individual user terminals 200, it is possible to reduce the data size on the user terminal 200 side.

The above is the viewing PDF generation processing.

According to such a viewing PDF generation system 1, it is possible to provide a viewing PDF generation system that enables viewing of the original PDF without depending on the environment of the user terminal 200. FIG. As a result, the data size on the user terminal 200 side can be suppressed, and the advantage of not having to add unnecessary rendering data to the user terminal 200 can be obtained.

[PDF display processing for viewing]
FIG. 4 is a diagram showing a functional configuration when the viewing PDF generation system 1 performs viewing PDF display processing. In addition to the configuration of FIG. 2, the cloud server 100 realizes the reference unit 105 and the output unit 106 in cooperation with the communication unit, the storage unit, and the processing unit when the control unit reads a predetermined program.

FIG. 5 is a flow chart showing viewing PDF display processing executed by the viewing PDF generation system 1. As shown in FIG. The flowchart in FIG. 5 is executed when the viewing PDF is displayed on the user terminal 200 in step S304 of the flowchart in FIG.

When performing viewing PDF display processing for displaying a viewing PDF on the user terminal 200, the reference unit 105 of the cloud server 100 refers to the link between the PDF generated in step S303, the embedded PDF, and the rendering data (step S501). .

After that, the output unit 106 of the cloud server 100 acquires necessary information from the link destination referred to in step S501 in response to the user terminal 200 viewing PDF display request, and outputs the viewing PDF to the user terminal 200 (step S502). The output here means displaying on an output device such as a display or liquid crystal via the input/output unit of the user terminal 200 . Alternatively, output such as reading by voice may be performed to an output device such as a speaker or an earphone.

The above is the viewing PDF display processing.

As described above, according to the viewing PDF display processing of the viewing PDF generation system 1, the original PDF can be viewed without depending on the environment of the user terminal 200 by obtaining the necessary information from the referenced link destination. is possible.

[PDF editing process for viewing]
FIG. 6 is a diagram showing a functional configuration when the viewing PDF generation system 1 performs viewing PDF editing processing. In addition to the configuration of FIG. 4, the cloud server 100 implements an editing unit 107 and an updating unit 108 in cooperation with a communication unit, a storage unit, and a processing unit by reading a predetermined program from the control unit.

FIG. 7 is a flow chart showing the browsing PDF editing process executed by the browsing PDF generating system 1. As shown in FIG. The flowchart in FIG. 7 is the processing when the user 2 attempts to edit the viewing PDF from the user terminal 200 after step S502 in the flowchart in FIG.

The editing unit 107 of the cloud server 100 first checks whether or not there is a request for editing the viewing PDF from the user terminal 200 (step S701). If there is an edit request, the process advances to step S702, and if there is no edit request, the PDF editing process for viewing ends.

When there is a viewing PDF editing request, the editing unit 107 of the cloud server 100 edits the viewing PDF based on the editing request for the viewing PDF from the user terminal 200 (step S702). Editing here means changing character strings, inserting images and movies, changing fonts, adding and deleting embedded PDFs, as well as changing character strings for embedded PDFs, inserting images and movies, changing fonts, Addition, deletion, or the like of the embedded PDF is assumed.

Finally, the update unit 108 of the cloud server 100 updates the PDF, the embedded PDF, and the rendering data stored in the cloud server 100 according to the content of the editing in step S702 (step S703). Here, when the data stored in the cloud server 100 is updated, a history of which user 2 performed what kind of editing may be stored together.

The above is the viewing PDF editing process.

Thus, according to the viewing PDF editing process of the viewing PDF generating system 1, the user 2 who has referred to the viewing PDF can edit the original PDF data. In addition, by storing the editing history in the cloud server 100 at that time, it becomes possible to check the history of which user 2 performed what kind of editing.

[Embedded PDF display switching process]
FIG. 8 is an example of a display screen of the user terminal 200 for allowing the user 2 to select which version to view when the embedded PDF has been updated. To enable selection of an embedded PDF to be displayed when an embedded PDF included in a viewing PDF has been updated.

FIG. 8 shows an example of displaying a message 801 on the input/output unit of the user terminal 200 stating "The embedded PDF embedded in the PDF you are trying to view has been updated by the user. Which version do you want to display?" is shown. Radio buttons 802 are selected as options for "embedded PDF embedded by user X when created", "embedded PDF updated by user Y at 2022/4/4 10:45:22", and "user X updated at 2022/4/21 17". : embedded PDF updated at 23:41", and "embedded PDF updated at 2022/4/4 10:45:22 by user Y" is selected. Here, by selecting the display button 803 , the viewing PDF including “the embedded PDF updated by user Y at 2022/4/4 10:45:22” is displayed on the user terminal 200 . It is assumed that the update history of the embedded PDF is obtained from the cloud server 100 that stores the editing history. Also, here, an example is shown in which it is possible to select the embedded PDF to be displayed when the embedded PDF contained in the PDF for viewing has been updated. It is also possible to display all parts in order.

The above is the embedded PDF display switching process.

In this way, according to the embedded PDF display switching process of the viewing PDF generation system 1, it is possible to select the embedded PDF to be displayed, and it is possible to provide a viewing PDF generation system that is more convenient for the user.

FIG. 8 shows an example in which the embedded PDF to be displayed can be selected when the embedded PDF included in the viewing PDF has been updated. In addition, when the viewing PDF editing process is performed, based on the editing history, the viewing PDF can be selected, the changed parts can be displayed side by side for comparison, and the changed parts can be displayed in order. A function of displaying all of them may be used.
