The present invention relates to a technology for providing a viewing PDF generation system that is independent of the terminal environment and allows viewing of the original PDF while suppressing the data size.

Conventionally, PDF (Portable Document Format) data has been used as an environment-independent data format for reports, product catalogs, electronic manuals, materials, and the like. With PDF, it is possible to embed other PDF data within PDF data (embedded PDF). However, when another PDF data (embedded PDF) is embedded in PDF data X, even if the embedded PDF is updated, another PDF data Y in which the same embedded PDF is embedded is not updated. Furthermore, when attempting to display a PDF on a terminal, if the terminal lacks rendering data such as font data, the original document data cannot be displayed.

For example, in Patent Document 1, when creating a PDF file of document information, each of a plurality of pieces of attached information attached to the document information is converted into audio data according to the provider of the document information, and an audio file of each attached information is created. A technique is provided for creating a PDF file and embedding the created audio file in the PDF file.

Furthermore, in Patent Document 2, in order to reduce the file size of a document file, specific code data is converted to Unicode data, editing is performed to specify the font of the Unicode data, and Unicode edited data is generated. All character data is generated by extracting the combinations of character codes and fonts used in the system so that the combinations do not overlap, and the characters extracted as all character data can be processed using font data held by the personal computer. The other characters are set as characters for which fonts are embedded, and the Unicode edited data is converted to the specified document format according to the settings, and the document file is technology is provided to obtain it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. In the subsequent figures, the same numbers or symbols are given 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 format. Furthermore, the term "embedded PDF" refers to another PDF data that is embedded within 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 a user 2 that creates and views PDFs. Although not shown in FIG. 1, it is assumed that the cloud server 100 and the user terminal 200 can communicate via the network 3. Further, it is assumed that a plurality of users 2 and user terminals 200 may exist. FIG. 1 illustrates a user 2A and his user terminal 200A, and a user 2B and his user terminal 200B. The cloud server 100 refers to a cloud computer, and may be realized by multiple computers instead of one computer. A cloud computer in this specification includes one that uses any computer in a scalable manner to perform a certain function, and one that includes multiple functional configurations to realize a certain system, and the functions can be freely combined. It can be any of the following. It is assumed that user 2 is participating in a 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 stored in the cloud server 100, or may be obtained from the user 2A via the user terminal 200A. When acquiring from the user terminal 200A, it may be created by the user 2A himself or may be acquired by the user 2A from another person. Further, the PDF may include an embedded PDF. Here, the embedded PDF refers to another PDF data embedded within PDF data. If there is no embedded PDF, there is no need to extract it. Furthermore, here, the rendering data refers to data necessary for rendering such as font data and codec. 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), and codec (Codec A) are extracted as rendering data from a PDF. Furthermore, font data (Font B) and codec (Codec B) are extracted as rendering data from the embedded PDF (File X). 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 include an embedded PDF, there is no need to store it.

Next, the generation unit 103 of the cloud server 100 creates a link based on the stored PDF, the embedded PDF, and the 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 providing unit 104 of the cloud server 100 provides the generated viewing PDF to the user 2B via the user terminal 200B (step S04). As a method for displaying the PDF for viewing on the user terminal 200B, the PDF for viewing generation system 1 may include a WEB viewer. The web viewer refers to the links between the stored PDF, the embedded PDF, and the rendering data, obtains necessary information from the referenced link, and outputs the viewing PDF to the user terminal 200B. shall be.

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, by referring to the rendering data of the viewing PDF, the user terminal 200B However, it is possible to display the correct PDF. Further, at that time, there is no need to install Font A on the user terminal 200B. Font A is not embedded as data in the viewing PDF either, but only link information, so there is no need to send or receive extra data. Further, by saving rendering data such as font data only on the cloud server side and not saving it on each user terminal 200, it is possible to suppress the data size on the user terminal 200 side.

As described above, according to the present invention, it is possible to provide a viewing PDF generation system that allows viewing of the original PDF without depending on the environment of the user terminal 200. Thereby, it is possible to obtain the advantage that the data size on the user terminal 200 side can be suppressed and there is no need to add unnecessary rendering data to the user terminal 200.

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

[Viewing PDF generation process]
Based on FIG. 3, the viewing PDF generation process executed by the cloud server 100 will be described. FIG. 3 is a flowchart showing the viewing PDF generation process executed by the viewing PDF generation system 1. The processing executed by each of the above-mentioned units will be explained along 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 one that has already been stored in the cloud server 100, or one that has been obtained from the user 2 via the user terminal 200. When acquiring the PDF from the user terminal 200, the PDF may be created by the user 2 himself or may be acquired by the user 2 from another person. Further, the PDF may include an embedded PDF. If there is no embedded PDF, there is no need to extract it. Furthermore, here, the rendering data refers to data necessary for rendering such as font data and codec. 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 include an embedded PDF, there is no need to store it.

Next, the generation unit 103 of the cloud server 100 creates a link based on the stored PDF, the embedded PDF, and the 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 providing unit 104 of the cloud server 100 provides the generated viewing PDF 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 outputs a PDF for viewing to the user terminal 200 by referring to links between the stored PDF, the embedded PDF, and the rendering data, and acquiring necessary information from the referenced link destination. shall be.

Here, whether or not the user terminal 200 providing the viewing PDF in step S304 includes rendering data such as font data and codec, the rendering of the viewing PDF of the linked destination is performed. By referring to the PDF data, it is possible to display the correct PDF. Further, since font data, codecs, etc. are not embedded as data in the PDF for viewing, but only link information is included, there is no need to send or receive extra data. Further, by saving rendering data such as font data only on the cloud server side and not saving it on each user terminal 200, it is possible to suppress the data size on the user terminal 200 side.

The above is the viewing PDF generation process.

According to such a viewing PDF generation system 1, it is possible to provide a viewing PDF generation system that does not depend on the environment of the user terminal 200 and allows viewing of the original PDF. This provides the advantage that the data size on the user terminal 200 side can be suppressed, and there is no need to add unnecessary rendering data to the user terminal 200.

[Viewing PDF display processing]
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 shown in FIG. 2, the cloud server 100 realizes a reference section 105 and an output section 106 by having a control section read a predetermined program, thereby cooperating with a communication section, a storage section, and a processing section.

FIG. 5 is a flowchart showing the viewing PDF display process executed by the viewing PDF generation system 1. The flowchart in FIG. 5 is assumed to be executed when the viewing PDF is displayed on the user terminal 200 in step S304 of the flowchart in FIG.

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

Thereafter, the output unit 106 of the cloud server 100 obtains necessary information from the link referenced 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). 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 audio reading may be performed to an output device such as a speaker or earphone.

The above is the viewing PDF display process.

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

[Viewing PDF editing process]
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 shown in FIG. 4, the cloud server 100 realizes an editing section 107 and an updating section 108 by having a control section read a predetermined program, in cooperation with a communication section, a storage section, and a processing section.

FIG. 7 is a flowchart showing the viewing PDF editing process executed by the viewing PDF generation system 1. The flowchart in FIG. 7 is a process performed 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 there is an editing request for the viewing PDF from the user terminal 200 (step S701). If there is an editing request, the process advances to step S702, and if there is no editing request, the viewing PDF editing process ends.

If there is a request to edit the PDF for viewing, the editing unit 107 of the cloud server 100 edits the PDF for viewing based on the editing request for the PDF for viewing from the user terminal 200 (step S702). Editing here includes changing text strings, inserting images and videos, changing fonts, adding and deleting embedded PDFs, as well as changing text strings, inserting images and videos, changing fonts, etc. It is assumed that this is an addition or deletion of an embedded PDF.

Finally, the updating 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 editing content in step S702 (step S703). Here, when updating the data stored in the cloud server 100, a history of what kind of editing was performed by which user 2 may also be saved.

The above is the viewing PDF editing process.

In this way, according to the viewing PDF editing process of the viewing PDF generation system 1, the user 2 who has referred to the viewing PDF can edit the original PDF data. Furthermore, by storing the editing history in the cloud server 100 at that time, it becomes possible to check the history of which user 2 has made 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 the embedded PDF included in a PDF for viewing has been updated.

In FIG. 8, a message 801 is displayed on the input/output section of the user terminal 200 saying, "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?" It shows. Select radio buttons 802 to choose from: "Embedded PDF created by user Embedded PDF updated at 2022/4/4 10:45:22'' is shown, and ``Embedded PDF updated by user Y at 2022/4/4 10:45:22'' is selected. Here, by selecting the display button 803, a PDF for viewing including "the embedded PDF updated by user Y on 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. In addition, here is an example in which it is possible to select which embedded PDF to display when the embedded PDF included in the viewing PDF has been updated. It is also possible to display all parts in order.

The above is the embedded PDF display switching process.

As described above, according to the embedded PDF display switching process of the viewing PDF generation system 1, it becomes 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 it is possible to select the embedded PDF to be displayed when the embedded PDF included in the viewing PDF has been updated. However, when the embedded PDF included in the viewing PDF has been updated, In addition, when editing a PDF for viewing, you can select which PDF to display based on the editing history, display the changed parts side by side for comparison, and display the changed parts in order. It may also be a function to display all.

The means and functions described above are realized by a computer (including a CPU, an information processing device, and various terminals) reading and executing a predetermined program. For example, the program may be provided from a computer via a network (SaaS: Software as a Service) or in a cloud service. Further, the program is provided in a form recorded on a computer-readable recording medium. In this case, the computer reads the program from the recording medium, transfers it to an internal recording device or an external recording device, records it, and executes it.
