Description

Drawing support device, display system, and drawing support method

The present invention relates to a drawing support device, a display system, and a drawing support method that support drawing using existing screen data.

The programmable display is usually connected to a device such as a programmable logic controller (hereinafter referred to as PLC (Programmable Logic Controller)), a sensor, a driving device, and an input / output device, and is used for displaying the state of the device and operating the device. .

In recent years, there is an increasing demand for displaying the state of the apparatus not only on a programmable display but also on a display device such as an ANDON, a large monitor or a portable terminal. The ANDON is a display device used for notifying the production state at the production site.

In response to these demands, it is conceivable to realize screen display on display devices such as ANDON, large monitors, and portable terminals using screen data created for programmable displays. However, since these display devices and programmable displays generally have different screen sizes, some changes are made to the screen data created for the programmable display.

On the other hand, if screen data corresponding to various screen sizes is generated, it is necessary to secure memory capacity in order to store these screen data. Patent Document 1 discloses a drawing support system capable of generating screen data corresponding to various screen sizes while suppressing memory capacity. The drawing support system described in Patent Document 1 suppresses memory capacity by converting screen data into relative information screen data including arrangement information relative to an arbitrary screen.

In the technique described in Patent Document 1, the same screen is converted into screen data corresponding to each screen size so that the same screen can be displayed according to the screen size on each display device having various screen sizes. In the technique described in Patent Document 1, since a plurality of assumed displays are different in screen size but are single, that is, all are programmable displays, the same screen is displayed in this way. No problem. On the other hand, when displaying on a display device other than the programmable display device, for example, a display device such as an ANDON, a large monitor, or a portable terminal, it may be desired to display a screen that is not completely the same screen as the programmable display device. For example, there may be a demand to display additional information on a screen displayed on a programmable display device on a display device, or to delete a part from the screen displayed on the programmable display device. In such a case, it is desirable that the existing screen data can be displayed on the screen in a size different from the screen size determined from the screen size. However, in the technique described in Patent Document 1, since existing screen data is converted as it is into screen data corresponding to each screen size, screen data is arranged when information is added to or deleted from the converted screen data. There was a problem that it was necessary to redo.

The present invention has been made in view of the above, and it is an object of the present invention to obtain a drawing support device capable of easily changing the size of screen data diverted when diverting existing screen data to create a display screen. Objective.

When the processing circuit is the control circuit 900 including a processor, the processor 901 is realized by reading and executing a program in which processing of each unit stored in the memory 902 is described. The memory 902 is also used as a temporary memory in each process performed by the processor 901.

When the processing circuit is dedicated hardware, the processing circuit is, for example, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

Next, the operation of this embodiment will be described. FIG. 5 is a diagram showing an example of screen information including screen data created by the drawing support device 1 of the present embodiment. The screen information is stored in the storage unit 13 of the drawing support apparatus 1 as described above. FIG. 5 shows a state where n screens from screen 1 to screen n (n is an integer equal to or greater than 1) have been created by the user. The screen information includes screen attribute information 7 which is attribute information for each screen. The screen data corresponding to one screen includes screen attribute information 7 and object information that is information on each object arranged on the screen. In FIG. 5, for example, screen data 6 that is screen data corresponding to the screen 1 includes screen attribute information 61 and an object information group 62 that is a set of object information. The screen attribute information 61 includes “screen 1” as information for identifying the screen and also includes the attribute information of the screen 1. In the example shown in FIG. 5, there are m objects arranged on the screen 1 from AAA1-1 to AAA1-m (m is an integer of 1 or more). Therefore, the object information group 62 includes object information corresponding to m objects. The object information includes the type and identification information of the object and attribute information of the object. AAA1-1 etc. are the type and identification information of each object. AAA is information indicating the type of object, and numerical values and symbols such as 1-1 and 1-m following AAA indicate the number of an object of the same type in the same screen as the number indicating the screen. For example, AAA1-1 is an object of the first AAA type on screen 1, AAA1-m is an mth AAA type object of screen 1, and AAA2-1 is the first object of screen 2. AAA type objects. The other screen data constituting the screen information has the same configuration as the screen data 6, but the content of the attribute information and the number of objects are determined according to the screen. Each type of object is generated in advance as an image. For example, when the object type is a meter, an image of the meter is generated in advance as an object. The image information includes image data of each object generated in advance. Alternatively, image data corresponding to each object may be included in the object information of the screen data.

Each screen data constituting the screen information is created by the creation unit 122. The creation unit 122 generates screen data of a screen to be displayed on the display device 2 based on an operation received from the user. A method for generating screen data for a screen to be displayed on the display device 2 is not particularly limited, and a general method can be used. For example, when the creation unit 122 receives an instruction to start creating screen data via the input unit 25, the creation unit 122 displays a creation screen for creating a new blank page on the display unit 24. For example, the creation unit 122 displays a list of selectable objects on the display unit 24, and the user selects an object via the input unit 25 and sequentially places it on a creation screen for new creation. Thereby, the object is arranged on the screen for new creation. When the object is placed on the screen and a save instruction is input via the input unit 25, the creation unit 122 stores data indicating the screen on which the object is placed in the storage unit 13 as screen data.

Next, creation of a screen to be displayed on the terminal 3 according to the present embodiment will be described. FIG. 6 is a flowchart illustrating an example of a procedure for creating a screen to be displayed on the terminal 3 according to the embodiment. When an instruction to start creating a screen to be displayed on the terminal 3 is input via the input unit 15, the process illustrated in FIG. 6 is started. First, the creation unit 122 displays a creation screen for creating a new screen on the display unit 14 (step S1). FIG. 7 is a diagram illustrating an example of a state in which a creation screen for creating a new screen is displayed. In the example illustrated in FIG. 7, a creation screen 101 for creating a new screen and a menu bar 102 are displayed on the display unit 14. The menu bar 102 includes a screen call button 103. When the user wants to arrange existing screen data on the creation screen 101 to be displayed on the terminal 3 by screen calling, the user clicks the screen calling button 103 when the input unit 15 is a mouse. Thereby, the screen call is selected.

Next, when screen calling is selected via the input unit 15 (Yes in step S2), the calling unit 123 displays a screen image list on the display unit 14 and accepts selection of the calling screen (step S3). The screen image list is a list of images corresponding to the screen data. The image corresponding to the screen data is, for example, a reduced image of the screen indicated by the screen data. Alternatively, a screen data name or a list of identification information may be displayed as the screen image list. Hereinafter, an example in which a reduced image of a screen corresponding to the screen data is displayed as the screen image list will be described.

Next, the calling unit 123 determines whether selection of a calling target is instructed (Step S4). The selection of a call target is a process that is performed to place objects in the called screen on a new screen in units of objects without placing the entire screen on the new screen among the screens to be called by calling the screen. In selecting a call target, the user selects an object to be placed on a new screen, that is, an object to be called, via the input unit 15.

If the selection of the call target is not instructed (No at Step S4), the calling unit 123 places the call screen on the creation screen (Step S7). When selection of the call target is not instructed, the entire called screen is arranged on the creation screen. That is, in this case, the calling image is the first screen. FIG. 8 is a diagram illustrating an example of a creation screen on which a screen including a screen image list and a call screen are arranged. An example of a screen 200 including a screen image list 201 is shown on the left side of FIG. 8, and an example of a creation screen on which a call screen is arranged is shown on the right side of FIG. In the example illustrated in FIG. 8, a screen image list 201 is displayed on the screen 200 together with a button 202 that is a button for “selecting a call target”, an OK button 203, and a cancel button 204. In the screen image list 201, an image 205 that is a reduced image of the screen 1 and an image 206 that is a reduced image of the screen 2 are displayed. When the user selects the image 205 of the screen image list 201 via the input unit 15 and clicks the OK button 203, the screen data of the screen 1 corresponding to the image 205 is arranged on the creation screen 101. A call screen 207 shows the screen 1 corresponding to the image 205 arranged on the creation screen 101. When the call screen 207 is arranged on the creation screen 101, a handle 208 is displayed together with the call screen 207. The user can change the size of the call screen 207 by operating the handle 208 via the input unit 15. Before the adjustment, the call screen 207 is displayed on the creation screen 101 with the same size as the screen displayed on the display device 2, for example.

When the adjustment unit 124 receives the size adjustment of the calling screen (step S8 Yes), the adjustment unit 124 calculates a ratio from the size after the size adjustment, and sets the calculated ratio in the screen data (step S9). Specifically, for example, when the call button 123 is clicked after a handle 208 is operated, the call unit 123 determines that the call screen size adjustment has been received. In addition, when the handle 208 is not operated and a confirmation button (not shown) or the like is clicked, the calling unit 123 determines that the call screen size adjustment is not accepted.

FIG. 9 is a diagram for explaining a ratio calculation method. On the left side of FIG. 9, a screen 301 created for the display 2 is shown, and on the right side of FIG. 9, a creation screen 302 being created for display on the terminal 3 is shown. On the creation screen 302, the screen 301 of FIG. As shown in FIG. 9, it is assumed that the size of the screen 301 is SX1 × SY1, the size of the creation screen 302 is DX × DY, and the size of the call screen after the size adjustment is OX1 × OY1. In this case, the adjustment unit 124 calculates the ratios X and Y by the following equation (1). SX1, DX, and OX1 indicate values in the horizontal direction, that is, the X-axis direction, and SY1, DY, and OY1 indicate values in the vertical direction, that is, the Y-axis direction. Further, the ratio X indicates the ratio in the horizontal direction, and the ratio Y indicates the ratio in the vertical direction.
X = OX1 ÷ SX1, Y = OY1 ÷ SY1 (1)

In the present embodiment, a ratio is used as information indicating the size of the calling image. As shown in the above formula (1), the ratio is information indicating the ratio of the size of the calling image to the size of the first screen. is there.

Further, the adjustment unit 124 calculates start point coordinates PX1 and PY1 in the creation screen 302 of the call screen 303. In the example shown in FIG. 9, the start point coordinates of the switch object 304 that is an object in the screen 301 are sox1 and soy1, and the start point coordinates of the switch object 305 corresponding to the switch object 304 in the creation screen 302 are dox1 and doy1. . Sox1, soy1 and dox1, doy1 have the relationship shown in the following equation (2). In the following, the coordinate values in each screen are positive in the horizontal direction toward the left, and positive in the vertical direction in the downward direction.
dox1 = PX1 + sox1 × X,
doy1 = PY1 + soy1 × Y (2)

When the size adjustment of the calling screen is not accepted (No at Step S8), the data generation unit 125 determines whether an instruction to end the screen creation is accepted (Step S10). When the instruction is accepted (Yes at Step S10), the creation is performed. The screen data corresponding to the screen is stored in the storage unit 13, and the process is terminated. At this time, when the size adjustment is performed, the data generation unit 125 generates object information corresponding to the calling screen using the ratio calculated by the adjustment unit 124 and assigns the object information to the screen data. If an instruction to end screen creation has not been received (No at step S10), the drawing support processing unit 121 repeats the processing from step S2.

FIG. 10 is a diagram showing a configuration example of screen information when a screen using screen calling is created. In the example illustrated in FIG. 10, the screen 1 is a screen created for the display device 2, and the screen 2 is a screen created for the terminal 3. On screen 2, screen 1 is arranged by screen calling. Therefore, the object information corresponding to the screen 2 includes information on the call screen 2-1 that is a call screen arranged on the screen 2. Here, the call screen is also handled as one object in this way. The attribute information on the call screen 2-1 includes the ratios X and Y described above. In the example shown in FIG. 10, an example is shown in which the screen ID (Identifier) and size are included as attribute information of each screen, and the object ID, size, and start point coordinates are included as attribute information corresponding to the object. Yes. The starting point coordinates are the coordinates of the upper left corner of the object in the screen. The object is a square or a rectangle. For example, even when a circular object is a drawn object, the object is a square or a rectangle including the circle. The screen ID is a number for identifying the screen. When the object is a call screen, the attribute information includes an object ID, a screen ID that is an ID of the call screen, a target object ID, a target area, start point coordinates, and a ratio. The object ID is a number for identifying the object. The target object ID and the target area are used when a call target selection to be described later is instructed. The object ID and the target area will be described later. When the color of the object can be changed, the attribute information of each object may include the color.

In step S4, when selection of the calling target is instructed (step S4 Yes), the calling unit 123 displays a calling target selection screen on the display unit 14 (step S5). When selection of the call target is instructed, the call image is specified in units of objects that are images constituting an area or a call screen. The call target selection screen is a screen for receiving selection of a call target object. After step S5, the calling unit 123 determines whether or not the calling target is selected (step S6). When the calling target is selected (step S6 Yes), the calling unit is arranged on the creation screen (step S7). ). As will be described later, for example, the call target is specified in area units or object units. When specified in units of areas, the objects included in the area become the call target. When the calling target is not selected (No at Step S6), the calling unit 123 repeats Step S6.

FIG. 11 is a diagram showing an example of a screen including a screen image list and a call target selection screen. A screen 200 including a screen image list 201 is shown on the left side of FIG. 11, an example of a selection screen 310 to be called is shown in the center of FIG. 11, and a creation screen 101 is shown on the right side of FIG. Yes. The screen 200 is the same as the example shown in FIG. When a button 202 that is a button for “selecting a call target” is selected after an image is selected in the screen image list 201 of the screen 200, a call target selection screen 310 is displayed. On the selection screen 310 to be called, a screen corresponding to the image selected in the screen image list 201, that is, a call screen is displayed. On the call screen displayed on the selection screen 310 to be called, an object in the call screen can be selected in area units or object units. When the user selects in units of objects, the radio button of “individual selection” at the top of the call target selection screen 310 is checked. When the user selects in units of areas, the top of the call target selection screen 310 is displayed. Check the “Select area” radio button.

In the example shown in FIG. 11, “select area” is checked, and the selection area 311 is selected. For example, the user selects the selection area 311 by a drag operation. When the selection area 311 is selected, a portion corresponding to the selection area 311 in the calling screen is arranged as an area 312 on the creation screen 101. The user can adjust the size of the area 312 with the handle, as in the case shown in FIG. If “individual selection” is checked, selection can be made in units of objects on the selection screen 310 to be called, and the selected object is arranged on the creation screen 101. As in the case shown in FIG. 8, the user can adjust the size of the arranged object with the handle.

FIG. 12 is a diagram illustrating an example of object information when a call target is selected in units of areas. In the example shown in FIG. 12, among the screen information, the screen 1 is called as the calling screen on the screen 2, and a part of the screen 1 is selected as the calling target. The object corresponding to this call target is the call screen 2-1 in the example of FIG. In the example shown in FIG. 12, the object information on the call screen 2-1 stores the start point coordinates and end point coordinates of the selected area as the target area. The start point coordinates and end point coordinates are indicated by coordinate values on the screen 1. The start point coordinates are the coordinates of the upper left corner of the target area, and the end point coordinates are the coordinates of the lower right corner. When the call target is selected on an object basis, the object ID corresponding to the selected object on the screen 1 is stored in the target object ID. For example, when the meter 1-1 that is an object constituting the screen 1 is selected as the call target object to be arranged on the screen 2, the object ID 001 of the meter 1-1 is the object information of the call screen 2-1. Stored in the target object ID.

Referring back to the description of FIG. 6, the calling unit 123 proceeds to step S8 after step S7, and subsequently executes step S9 and subsequent steps. However, as described with reference to FIG. 11, in step S <b> 8 when the call target is selected, the size of the selected area or the selected object is adjusted instead of the entire call screen. Accordingly, in step S9 when the call target is selected, the call unit 123 calculates the size according to the above equation (1) as OX1 × OY1, and the size of the selected area after the size adjustment. Alternatively, the size of the selected object after the size adjustment is used.

If the screen call is not selected in Step S2 (No in Step S2), the calling unit 123 proceeds to Step S10. If the size adjustment of the calling screen is not accepted at step S8 (No at step S8), the calling unit 123 proceeds to step S10. In this case, the ratio is set to 1 for both X and Y.

In the above description, the operation when the screen call is selected has been described. However, in addition to the screen call, processing other than the screen call such as placing a new object on the creation screen may be performed. Processing other than the screen call is performed at an arbitrary timing among the processing shown in FIG.

As described above, in the drawing support device 1, screen data for the terminal 3 is generated, and the generated screen data is stored in the storage unit 13. The display 2 acquires screen information including screen data for the terminal 3 from the drawing support device 1 and stores it in the storage unit 23. The terminal 3 acquires screen information from the display device 2 and performs screen display using the screen data for the terminal 3 included in the screen information. Note that the terminal 3 may acquire image information from the drawing support device 1 without using the display device 2.

FIG. 13 is a flowchart showing an example of a screen display processing procedure in the terminal 3. First, the terminal 3 acquires screen information from the display device 2 (step S21). Specifically, the acquisition unit 322 of the terminal 3 transmits a screen information acquisition request to the display device 2 via the communication unit 31. Then, the calculation unit 22 of the display 2 transmits the screen information stored in the storage unit 23 to the terminal 3 via the communication unit 21. The acquisition unit 322 of the terminal 3 receives the screen information transmitted from the display device 2 via the communication unit 31 and stores it in the storage unit 33. Although the example in which the terminal 3 acquires the entire screen information has been described here, screen data corresponding to the display target screen and screen data called from the screen data may be acquired instead. In this case, specifically, for example, the terminal 3 confirms from the screen information whether the calling screen is in the screen data, and if the calling screen is in the screen data, acquires the corresponding screen data.

Next, the display control unit 323 of the terminal 3 acquires call screen information, that is, object information of the call screen from the display target screen data (step S22). Specifically, the display control unit 323 extracts display target screen data from the screen information stored in the storage unit 33, and acquires call screen information, that is, call screen object information from the screen data. The object information of the call screen includes an object ID, a screen ID, a target object, a target area, and a ratio as illustrated in FIG. Of these pieces of information, information not set is stored blank or a value indicating that it is not set. For example, when called on a screen basis, the target object and the target area are information that is not set.

Next, the display control unit 323 obtains the screen ID from the information on the calling screen, that is, the object information on the calling screen (Step S23). Next, the display control unit 323 determines whether or not the target object ID is set in the information on the calling screen, that is, the object information on the calling screen (step S24). If set (step S24, Yes), the display control unit 323 sets the object of the target object ID of the acquired screen ID as a display target (step S25). Specifically, the display control unit 323 searches the screen information of the acquired screen ID from the screen information of the storage unit 33, and the object corresponding to the target object ID described above from the object information of the screen data obtained by the search. Search for items containing ID. The display control unit 323 sets the object of the object ID obtained by this search as a display target.

Next, the display control unit 323 calculates the size and coordinates for displaying the display target from the information on the calling screen, that is, the ratios X and Y in the object information on the calling screen (step S26). The size and coordinates for displaying the display target are the size and starting point coordinates of the call screen or the call target when the call screen or the call target is displayed. Specifically, the display control unit 323 calculates the size and coordinates for displaying the display target using the ratios X and Y in the object information. A method for calculating the size and coordinates for displaying the display target will be described later.

The display control unit 323 displays the display target on the display unit 34 based on the calculated size and coordinates (step S27), and ends the process. When a screen other than the call screen is displayed on the creation screen created for display on the terminal 3, the object is subsequently displayed based on the screen data.

In step S24, if the target object ID is not set (step S24: No), the display control unit 323 determines whether the target area is set (step S28). When the target area is set (step S28 Yes), the display control unit 323 sets the object in the target area of the screen corresponding to the screen ID acquired in step S23 as the display target (step S29), and proceeds to step S26. .

If the target area is not set (No in step S28), the display control unit 323 sets all objects in the screen corresponding to the screen ID acquired in step S23 as display targets (step S30), and proceeds to step S26.

Here, a method of calculating the size and coordinates to be displayed in step S26 will be described. For each object to be displayed, the display control unit 323 determines the size and start point coordinates of the object on the display screen displayed on the display unit 34 as follows. The size of the entire display screen displayed on the display unit 34, that is, the size of the creation screen described above is DX and DY. When the display target is the object specified by the target object ID, the display control unit 323 determines the object from the object information of the object corresponding to the target object ID in the screen data corresponding to the screen ID acquired in step S23. The sizes rx1 and ry1 are acquired. Further, the display control unit 323 extracts the start point coordinates PX1 and PY1 from the object information on the calling screen acquired in step S22. The display control unit 323 calculates the sizes OX1 ′ and OY1 ′ for displaying the object and the start point coordinates PX1 ′ and PY1 ′ for displaying the object by the following equations (3) and (4).
PX1 ′ = PX1, PY1 ′ = PY1 (3)
OX1 ′ = rx1 × X, OY1 ′ = ry1 × Y (4)

If the display target is an object in the target area, the display control unit 323 extracts the start point coordinates and end point coordinates of the target area from the object information on the call screen acquired in step S22. From the extracted start point coordinates and end point coordinates and the object information of the screen data corresponding to the screen ID acquired in step S23, the object information of the object included in the target area is extracted from the screen data corresponding to the screen ID. For each object, the start point coordinates bx1, by1 of the object and the sizes rx1, ry1 of the object are acquired. For each object to be displayed, the display control unit 323 calculates the size OX1 ′, OY1 ′ for displaying the object and the start point coordinates PX1 ′, PY1 ′ for displaying the object by the following equations (5), (6). PX1 and PY1 are the start point coordinates included in the object information of the calling screen acquired in step S22.
PX1 ′ = PX1 + bx1 × X,
PY1 ′ = PY1 + by1 × Y (5)
OX1 ′ = rx1 × X, OY1 ′ = ry1 × Y (6)

When the display target is an object in the target area, the display control unit 323 applies the above formula (5) based on the object information to all objects constituting the screen data corresponding to the screen ID acquired in step S23. ) And (6), the sizes OX1 ′ and OY1 ′ for displaying the objects and the start point coordinates PX1 ′ and PY1 ′ for displaying the objects are calculated.

The drawing support device 1 according to the present embodiment may further automatically adjust the size when arranging a plurality of screens by screen calling as described below. FIG. 14 is a flowchart illustrating an example of an automatic size adjustment processing procedure when a plurality of screens are arranged by screen calling. When an instruction to start creating a screen to be displayed on the terminal 3 is input via the input unit 15, the process illustrated in FIG. 14 is started. The creation unit 122 first displays a creation screen for creating a new screen on the display unit 14 (step S41). Next, the calling unit 123 determines whether or not multiple screen calling has been selected (step S42). The selection of calling multiple screens is performed by providing a button for selecting calling multiple screens on the menu bar 102 shown in FIG. 7, and clicking this button. If the multiple screen calling is not selected (No at Step S42), the calling unit 123 ends the process.

When multiple screen calling is selected (step S42: Yes), the calling unit 123 displays a screen image list on the display unit 14 (step S43). FIG. 15 is a diagram illustrating an example of the screen displayed in step S42. On the left side of FIG. 15, a screen 500 including a screen image list 501 is displayed on the display unit 14. In this screen 500, a check box 502 for setting whether to display by specifying the number of divisions, an input field 503 for inputting the number of vertical divisions, and an input for inputting the number of horizontal divisions A column 504 is displayed. When the user designates the number of divisions to display, the user can check the check box 502 and input numerical values in the input field 503 and the input field 504. The number of divisions is a value indicating how many divisions of the creation screen are displayed. For example, when the number of horizontal divisions is designated as 2 and the number of vertical divisions is designated as 2, the creation screen is divided into 2 parts horizontally and 2 parts vertically, for a total of four divided areas. . A call screen can be arranged in each of the divided areas.

When the screen, that is, the calling screen and the number of divisions are selected (Yes in step S44), the calling unit 123 determines the ratio and arrangement according to the number of divisions for the calling screen arranged in each divided area ( Step S45). The arrangement is indicated by, for example, start point coordinates. The calling unit 123 arranges the selected call screen on the creation screen based on the determined ratio and arrangement (step S46). The right side of FIG. 15 shows a state where a plurality of call screens are displayed on the creation screen 101.

In this case, it is assumed that the number of divided areas and the number of selected screens are the same. When the number of selected screens is larger than the number of divided areas, the calling unit 123 may display an error, or create a part of the number of selected calling screens. You may make it arrange | position to. When the number of selected call screens is smaller than the number of divided areas, the calling unit 123 does not arrange the call screens in a part of the divided areas.

In step S45, the calling unit 123 determines the ratios X and Y and the start point coordinates for each calling screen, for example, as follows. The size of the creation screen is DX × DY, the number of divisions in the horizontal direction is KX, the number of divisions in the vertical direction is KY, and the original size of the call screen created for the display 2 is SX1, SY1. To do. At this time, the ratios X and Y are calculated by the following equation (7).
X = (DX ÷ KX) ÷ SX1, Y = (DY ÷ KY) ÷ SY1 (7)

The starting point coordinates PX _{i, j} , PY _{i, j} of the call screen arranged i th (i is an integer of 1 or more) from the left and j (j is an integer of 1 or more) from the top are expressed by the following formula (8 ).
PX _{i, j} = (i−1) × (DX ÷ KX),
PY _{i, j} = (j−1) × (DY ÷ KY) (8)

As for which call screen is arranged in which area, a predetermined arbitrary rule may be used, or it may be selectable by the user.

Returning to the description of FIG. 14, after step S <b> 46, as in step S <b> 10 of FIG. 6, it is determined whether an instruction for screen creation end has been accepted (step S <b> 47). The screen data corresponding to is stored in the storage unit 13 and the process is terminated. At this time, the data generation unit 125 generates object information corresponding to the call screen using the calculated ratio and start point coordinates, and assigns the object information to the screen data. If an instruction to end screen creation has not been received (No in step S47), the drawing support processing unit 121 repeats the processing from step S42. The normal calling process is a process after step S2 in FIG.

As described above, the screen information including the screen data corresponding to the creation screen in which a plurality of call screens are arranged is displayed via the display device 2 in the same manner as the screen information including the screen data created by the processing using FIG. Is received by the terminal 3. Using the screen information, the terminal 3 can display a screen on which a plurality of call screens are arranged by the process shown in FIG. That is, in this case, the calling image is a plurality of first screens, and the calling unit 123 receives an input of the number of divisions for dividing the new screen, and based on the number of divisions, the calling screen is displayed on the plurality of first screens. The arrangement positions and sizes of the plurality of first screens for arranging the plurality of screens are calculated, and the plurality of first screens are arranged on the second screen based on the calculated arrangement positions and sizes.

The drawing support device 1 of the present embodiment may further set editability information for each screen. The creation unit 122 receives a setting for whether or not editing is possible when the screen is called as a call screen for each screen via the input unit 15 from the user. That is, when the first screen is used as a call image, the creation unit 122 receives input of information indicating whether the call image can be edited. FIG. 16 is a diagram illustrating an example of an editing permission / inhibition setting screen. The setting screen 401 shown in FIG. 16 is displayed on the display unit 14 when, for example, a screen is created. The setting screen 401 includes a check box 402 for setting whether to permit size change and a check box 403 for setting whether to allow color change. The setting screen 401 further includes a check box 404 for setting whether or not to allow position change, a check box 405 for setting whether or not to allow addition of an object, and deletion of an object. It includes a check box 406 for setting whether or not. For example, the creation unit 122 accepts various editable settings on the setting screen 401 illustrated in FIG. 16.

FIG. 17 is a diagram illustrating an example of screen data in a case where editability is set. As shown in FIG. 17, the screen data includes information indicating whether each edit item for which editability is set can be edited or cannot be edited. That is, the first screen data includes information indicating whether editing is possible. The information indicating whether editing is possible or not is, for example, 1 when editing is possible and 0 when editing is impossible. FIG. 17 shows an example in which the color of each object can be changed, and the attribute information includes the color. FIG. 18 is a diagram illustrating an example of a creation screen in a case where a screen in which size change is not possible is called as a call screen. In the example shown in FIG. 18, a handle for changing the size is not displayed on the call screen 600. When a screen that is set to allow resizing is called, a handle is displayed and resizing is possible.

As described above, in this embodiment, when creating a new screen to be displayed on a device different from the device on which the existing screen is displayed using the existing screen, the new screen is arranged on the new screen. Added support for resizing existing screens. This makes it possible to easily change the size of the existing screen data when creating a display screen using the existing screen data. In the present embodiment, it is possible to select a target to be arranged on a new screen in area units or object units in an existing screen. Thereby, a new screen can be flexibly created according to the size and application of the device to be displayed.

The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention.
