The difference file is used for exchange between an editor program and the server on a web page to exchange only necessary information.SELECTED DRAWING: Figure 11

Description

  The present invention relates to a process (overlay output) for generating form document data by overlaying a form (form information file) created by a form creation device and text format data (field data), and displaying the generated form document data. It relates to editing and saving methods.

  In recent years, an increasing number of companies replace information on paper media with electronic data for the purpose of improving business efficiency and saving resources by making paperless. For example, business forms that are operated in-house are often the target, especially because the forms output by the core system output a large number of pages and the operation cost becomes enormous. Is being actively promoted.

  In addition, cloud computing systems have begun to spread as a form of managing business data and various processes on the server computer side. The user accesses the Web page of the cloud server computer from the browser of the client computer via the Internet, and browses the document document data digitized on the Web page. Furthermore, an increase in use cases is expected in which the form document data being browsed is edited and printed according to the business flow.

  Patent Document 1 discloses a technique for excluding a deletion-processed page or data unrelated to drawing from a transmission / reception object when editing / printing digitized document document data on such a Web page. .

JP 2013-130989 A

  When editing digitized document document data on a Web page, a transparent field element is added to the document data for viewing in order to define that the field is editable. Since this transparent field element does not affect drawing, it is not necessary when the form document data is converted again into the form document data for viewing after editing.

  In addition, since the form document data before editing is stored on the cloud server computer, it is inefficient to send all form document data from the client computer to the cloud server computer when only a part of the data is edited. is there.

  In this way, the edited form document data includes data that does not affect drawing or that is not different from the data on the cloud server computer, and it is efficient to transmit all of these data when saving There is no problem.

  The present invention has been made in view of the above problems, and an object thereof is to provide more various browsing, editing, and saving functions for form document data on a Web page.

  Embodiments according to the present invention will be described below with reference to the drawings.

  First, general overlay output will be described.

  Overlay output refers to printing by superimposing form information for recording information such as frame lines in document paper format and text format data (field data). A function called page registration or form registration possessed by a page printer such as a laser printer is used to register in advance as form information. When printing with field data using this page printer, the form information and the field data can be overlaid and printed by using a function called page information call or form information call. Such overlay printing is defined as overlay output. It is also possible to output the overlay output result as an electronic file by using a virtual printer instead of paper.

  FIG. 1 is a diagram showing a system configuration example of the present embodiment.

  The system shown in FIG. 1 includes a form generation server 101 and a client device 102. The form generation server 101 is an information processing apparatus according to the present embodiment, and executes overlay output processing and generation processing of an electronic form browsing program. That is, the form generation server 101 generates a print page by superimposing a field data file that is text data and a form information file including predetermined form information, and instructs the virtual printer to output the generated print page as an electronic file. Generate as Then, a form browsing program capable of browsing and editing the form is generated using the generated electronic file form file.

  The form browsing program of this embodiment is a web application that runs on a web browser that can be distributed via a network. In many cases, these web applications are applications that operate using a mashup language (HTML) that represents a web page and a programming language (JavaScript (registered trademark)) that runs on a web browser. Since the form browsing program is an application displayed on a web browser, it will also be referred to as a form browsing screen hereinafter.

  In addition to a web application that runs on a web browser, an application that runs on a computer system may be used. Further, the form generation server 101 generates only an electronic form file and a file representing inter-field calculation described later, and includes an application that can reproduce a document browsing / editing operation described later using the file on the client device 102 side. A simple configuration may be used.

  The form generation server 101 receives a request from the client apparatus 102 and performs the overlay output process and the form browsing program generation process.

  In addition, each of the above-described components is connected to be communicable via a network 100. The network is, for example, a LAN such as the Internet, a WAN, a telephone line, a dedicated digital line, an ATM, a frame relay line, a cable TV line, a data broadcasting wireless line, or the like. Moreover, it is what is called a communication network implement | achieved by these combination. The network only needs to be able to transmit and receive data.

  FIG. 2 is a block diagram illustrating a hardware configuration of the form generation server 101 and the client apparatus 102 in FIG.

  Reference numeral 201 denotes a CPU that directly or indirectly controls each device (ROM, RAM, etc. described later) connected by an internal bus and executes a program for realizing the present invention. A ROM 202 stores the BIOS. A RAM (direct storage device) 203 is used as a work area of the CPU 201 or used as temporary storage for loading software modules for realizing the present invention.

  Reference numeral 204 denotes an indirect storage device such as an HDD (hard disk drive) or an SSD (solid state drive) in which an OS or software module as basic software is stored. Reference numeral 205 denotes an input device such as a keyboard or pointing device (not shown). Reference numeral 206 denotes an output device to which a display is connected. Reference numeral 207 denotes an I / F for connecting to the network 100.

  In these hardware, after starting, the BIOS is executed by the CPU 201 and the OS is loaded from the HDD 204 to the RAM 203 so as to be executable. The CPU 201 loads various software modules (to be described later) from the HDD 204 to the RAM 203 in an executable manner according to the operation of the OS. Various software modules are executed and operated by the CPU 201 in cooperation with the above devices. The I / F 207 is connected to the network 100 and is controlled by the CPU 201 in accordance with the operation of the OS to realize communication by the communication means described above.

  FIG. 3 is a diagram illustrating a configuration example of a software module that operates on the form generation server 101. Each software module is stored in the HDD 204 shown in FIG. 2, and is loaded into the RAM 203 and executed by the CPU 201 as described above.

  The access control unit 301 receives a request from the client device 102.

  The page generation unit 302 generates a Web page for returning a response to the client device 102. Files such as HTML and JavaScript required for the web application that is the form browsing program are also generated by the page generation unit 302 and returned to the client apparatus 102.

  The file conversion unit 304 performs mutual conversion between a form page (PDF) generated by the form generation unit 303 and a file (SVG) in a format that can be displayed by a web browser.

  The form generation unit 303 generates print data by superimposing the form information in the form information file received by the access control unit 301 and the field data in the field data file.

  Then, the form page generation unit 304 generates a form page as an electronic file from the generated print data using software such as a virtual printer. In the case of this embodiment, the form generation unit 303 generates a form page in PDF format.

  FIG. 4 is a diagram showing the configuration of the fall information file 401.

  The form information file 401 can be created using a dedicated form information design system. The form information is generally composed of a fixed figure (form figure) that does not depend on field data and a figure (field figure) that displays received field data in accordance with a specified output format. In order to create a field graphic, it is necessary to create an item (field) for receiving field data in advance. Fields can be created from a dedicated screen displayed in the form information design system. When a field graphic is created, it is internally associated with the field from which it was created. In the case of a tabular field figure (table figure) 402, it is necessary to create record fields 405 and 406 because it is necessary to receive field data in record units.

  The field format for generating field data by counting with the specified counting method is defined as a counting field. In the case of the field graphic 403, it is necessary to create a total field 407 to indicate which field and what total method are specified.

  A field format that receives single data and does not change field data even when the page changes is defined as a fixed field. In the case of a field graphic 404 representing a signature graphic, a fixed field 408 needs to be created.

  The type of data stored in each field is defined by the “data type” attribute of the field.

  FIG. 5 is a diagram for explaining an example of overlay output processing by the form generation server 101.

  The form generation unit 303 of the form generation server 101 reads the form information file 401 in which the field graphic received by the access control unit 301 is defined, and the field data file 501. Then, the form generation unit 303 executes overlay output by superimposing the read form information file 401 and the field data file 501. Reference numeral 502 in FIG. 4 represents form document data as an overlay output result.

  Next, a specific operation of the present embodiment will be described.

  FIG. 6 is a diagram showing a sequence of processing for generating an editable form browsing screen in the embodiment of the present invention.

  In step S <b> 601, the user transmits a browse screen generation request to the form generation server 101 using the web browser of the client apparatus 102. It is necessary to attach file information and form data for overlay processing in the browse screen generation request.

  In step S <b> 602, the form generation unit 303 of the form generation server 101 performs overlay output processing using the form information file and the field data file acquired via the access control unit 301.

  Details of the overlay processing will be described below with reference to FIG.

  FIG. 7 is a flowchart showing an operation of designating a form information file and a field data file and outputting an overlay in the form generation server 101 according to the embodiment of the present invention.

  In S701, the layout configuration of the output form is calculated using the form information and field data included in the browse screen generation request in S601.

  In S702, in accordance with the layout configuration obtained in S701, drawing commands for each figure (a form figure that does not depend on field data and a field figure that depends on field data) are sequentially performed.

  In step S <b> 703, the form generation unit 303 determines whether the drawing command executed in step S <b> 702 is a field graphic drawing command.

  In step S <b> 703, when the form generation unit 303 determines that the drawing instruction executed in step S <b> 702 is a field figure drawing instruction, the form generation unit 303 performs the process of step S <b> 704. In step S703, when the form generation unit 303 determines that the drawing command executed in step S702 is not a field figure drawing command, the form generation unit 303 performs determination processing in step S706.

  In step S <b> 704, the form generation unit 303 acquires information on the target field of the drawing command executed in step S <b> 702. The information to be acquired includes the field name of the target field graphic, the type of the field graphic (record field, summary field, etc.), the data type of the field data, the drawn field data, and the drawing position of the data.

  In step S705, the form generation unit 303 records the field information 701 acquired in step S704 in the RAM 203 of the form generation server 101 for processing to be described later. In this embodiment, the field information 701 is a JSON format.

  In step S706, the form generation unit 303 determines whether all drawing commands have been completed.

  If it is determined in step S706 that all drawing commands have not been completed, the form generation unit 303 returns to step S702 and performs the next drawing command.

  If it is determined in S706 that all drawing commands have been completed, the form generation unit 303 performs the process of S707.

  The above is the description of the overlay processing using FIG. 7, and the description returns to FIG.

  In step S603, the form generation unit 303 uses the PDL information (page description language for instructing the printer to draw) as a result of the overlay process S603 to generate a PDF form form page via the virtual printer. . When generating a PDF form page, the field information 701 recorded in step S705 is read from the RAM 203 of the form generation server 101 and stored in the PDF file as metadata of the PDF form page.

  In step S604, the file conversion unit 304 converts the PDF format form page generated in step S707 into an SVG (scalable vector graphics) form page. Since the form page in PDF format cannot be edited directly on the web browser, it is changed to a format that can be edited (SVG format in this embodiment). When generating an SVG form page, the field information stored in the metadata of the PDF form page is embedded in the SVG form page. The format of the field information embedded in the SVG form page is not limited as long as it can express which field represents a certain area on the SVG form page. In this embodiment, field information is embedded as a SVG Script tag as indicated by 810.

  In step S608, the file conversion unit 304 records the SVG form form page converted in step S604 in the HDD 204 of the form generation server 101 for processing to be described later.

  In step S605, the page generation unit 302 of the form generation server 101 generates an editable form browsing screen. The editable form browsing screen that is generated includes a JavaScript program for controlling the SVG format form page and form page file generated in S604, and for controlling browsing, editing, and printing operations.

  In step S <b> 606, the form generation server 101 returns the editable form browsing screen generated in step S <b> 605 to the client apparatus 102.

  In step S <b> 607, the client apparatus 102 receives a response from the form generation server 101, and displays an editable form browsing screen on the web browser. The displayed editable form browsing screen is as shown in FIG.

  The above is the description of the sequence of the process for generating the editable form browsing screen using FIG.

  FIG. 8 is a diagram showing an editable form browsing screen 801 in the embodiment of the present invention.

  An area 802 displays an SVG form page. When a flick operation in the horizontal direction is performed in the area 802, switching to the previous or next form page can be performed.

  An editable field definition element 803 is a Javascript program for controlling the operation of viewing, editing, and printing a form page file by using field information 701 recorded on the form page 810 in the SVG format. Generated automatically when the screen is displayed.

Reference numeral 804 denotes a button for saving the currently displayed form page.
When the user performs a click operation in the area 801, the editing program in the editable form browsing screen operates and performs an editing process as shown in FIG.

  FIG. 9 is a flowchart showing the flow of editing processing performed on the form browsing screen in the embodiment of the present invention.

  In step S901, the user performs a click operation in the editable form browsing screen 801 area.

  In S902, the editing program in the editable form browsing screen (hereinafter abbreviated as “editing program”) determines whether or not the position clicked in S901 is within the editable field 803 area. One of the determination methods is a method of determining whether the coordinates of the clicked position are included in the editable field 803 recorded in the form page SVG. Another determination method is to generate an editable element (for example, button) using field information 701 in advance when displaying the browsing screen.

  If it is determined in S902 that the clicked position is within the editable field 803 area, the editing program executes the process of S904.

  If it is determined in step S902 that the clicked position is not within the editable field 803 area, the editing program is terminated and the editing process is terminated.

  In S904, the editing program stores the form document data as of S904. It is desirable to hold in the storage area of the web browser or the memory area where the editing program is executed.

  In step S905, the user edits data using a mouse / keyboard or the like in the editable field 803.

  In S906, the editing program temporarily holds the form document data. It is desirable to hold in the storage area of the web browser or the memory area where the editing program is executed.

  In step S907, the editing program compares the form document data saved in step S904 with the form document data saved in step S906, and creates an edit difference patch file.

  FIG. 10 is a diagram showing a save processing sequence when the save button on the editable form browsing screen is pressed in this embodiment.

  In step S <b> 1101, the user presses the save button 804 on the editable form browsing screen 1001.

  In step S <b> 1102, the client apparatus 102 transmits a form storage request to the form generation server 101. The form saving request includes an edit differential patch file created from the form document data before and after editing held on the current client device 102 side.

  In step S1103, the file conversion unit 304 applies the edit difference patch file in the request in step S1102 to the form document data stored in the HDD 204 in step S608.

  In step S1104, the file conversion unit 304 converts the form document data in the SVG format created in step S1103 into the PDF format.

  In step S1106, the form generation unit 310 returns the PDF file generated in step S1104 to the client device. In step S1107, the client apparatus 102 downloads the PDF file returned in step S1106.

  In the first embodiment, patches are created by comparing form document data before and after editing. On the other hand, in a core system or the like, a large amount of form document data is output. The process of creating a patch from two forms document data of a large number of pages is heavy.

  In the second embodiment, it is possible to save the processing of acquiring the difference before and after editing in S907 by saving which page the editing operation is performed and performing the difference acquisition process only for the page.

  FIG. 11 is a diagram illustrating an editing process sequence when an editable form browsing screen is clicked in the editable form browsing screen in the second embodiment.

  In S1201, the user clicks in the editable form browsing screen.

  In step S1202, the editing program determines whether the clicked location is within the editable form browsing screen.

If it is determined in S1202 that the screen is in the editable form browsing screen, the editing program determines in S1204 whether the clicked page has been edited.

  If it is not determined in step S1202 that the screen is within the editable form browsing screen, the editing process is terminated without doing anything.

  If it is determined in S1204 that the page has not been edited, the page number is stored in S1205. It is desirable to hold in the storage area of the web browser or the memory area where the editing program is executed.

  If it is determined in S1204 that the page has been edited, the form document data is saved in S1206.

  In step S1207, the user inputs data in the editable field 803.

  In step S1208, the editing program determines whether the position clicked in step S1207 is within the editable form browsing screen.

  If it is determined in S1208 that the editable form browsing screen has been clicked, it is determined in S1204 whether the clicked page has been edited.

  If it is determined in step S1208 that the editable form browsing screen has not been clicked, the editing program does nothing.

  In step S1209, the user clicks the save button 804.

  In step S1210, the editing program compares the form document data before and after editing with respect to the page number saved in step S1205, and acquires the difference.
