Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to a compound document processing device that synthesizes another document block onto a basic compound document page in which various document blocks coexist.

(Prior Art) In recent years, compound documents have been developed in which desired document blocks (actual data portions) are synthesized on a basic compound document page in which various document blocks such as text, tables, graphs, figures, images, etc. are arranged in independent areas. A compound document processing device that prints out pages has been developed. Here, the area where each document block constituting the basic compound document page is placed is called the basic vA area, and the area 1 where the document block to be combined with the basic combined document page is placed is called the transparent area. .

In conventional compound document processing devices, when handling a basic area or a transparent area, only the target area is displayed on the screen, and the two areas are not displayed overlappingly.

In other words, in conventional compound document processing devices, overlapping of some basic areas (a basic document page consisting of various document blocks arranged independently) and a transparent area (document blocks arranged in the transparent area) is not possible at the time of printing. only. For this reason, conventionally, it has not been possible to grasp the printed image of the target compound document page on which the transparent areas are superimposed on the display screen.

Furthermore, in conventional compound document processing devices, in order to switch the processing target from the basic area to the transparent area or from the transparent area to the basic area during editing, etc., an operation that temporarily ends the processing related to the current target area is performed. After that, it is necessary to perform an operation for specifying processing related to the target area, which cannot be easily and quickly performed.

(Problems to be Solved by the Invention) As described above, in the conventional compound document processing device, the print image of the compound document page created by overlapping the document block placed in the transparent area on the basic document page is displayed on the display screen. There was a problem in that it was not possible to grasp the situation and it was not possible to easily switch between areas.

This invention has been made in view of the above circumstances, and its purpose is to provide a transparent area (to The printed image of the target compound document page can be grasped on the display screen by superimposing and displaying the arranged document blocks), and the area can be switched between the basic side area and the transparent area without complicated operations. An object of the present invention is to provide a compound document processing device that can be processed extremely easily.

[Structure of the Invention] (Means and Effects for Solving the Problems) This invention provides a basic compound document page consisting of various document blocks arranged independently in a first type of area where mutual overlapping is prohibited. lt
! A compound document page in which document blocks placed in a second type of area in which overlap with a second type of area is allowed is displayed on the screen through the viewport, while switching of the processing target area is specified by the area switching specifying means. If the processing chain [
The type of area being processed at that time is determined by referring to the identification means, and if the first type of area is being processed, the processing target area is switched to the second type of area and the processing fAl is Update the contents of W & another means, and if the second type of area is being processed, switch the processing target #4 area to the first mallet area to which the center position of the view boat or cursor position belongs, and change the area being processed. The content of the identification means is updated, from the first type of area to the second FIi term area, or from the second type of area to the first type))V

An area management table 16 in which area information (area information) is set, and an area or buffer 18 in which data (document blocks) of each area is stored in units of areas are secured. In addition, here,
For the sake of simplicity, we will explain the case where a compound document is composed of one compound document page (1 page), but if there are multiple compound document pages (
(multiple pages), the area management table 16 is prepared for each page.

22 is a keyboard; 24 is a pointing device, for example a mouse having a left button 2G and a right button 28;
30 is an input interface that controls input from the keyboard 22 and mouse 24. 32 is a display monitor such as a CRT monitor; 34 is a bitmap memory that stores the screen data displayed on the display monitor 32 as a bit image; and 36 is a memory that updates the contents of the bitmap memory 34 and displays the screen on the display monitor 32. This is a display processor that performs display. The memory 12, input interface 30, and display processor 36 are connected to an internal bus 38 of the contour processor 10.

FIG. 2 shows the structure of the area management table 16. The area management table 16 includes a plurality of area information fields 40 in which the above area information is set for each area, and a current registration number field 42 in which the number of areas (area information of) currently registered in the table 16 is set. , a maximum registration number field 44 in which the maximum number of area VAs (area information) that can be registered in the table 16 is set, and a processing area ID number in which the ID number (identification number) of the area currently being processed is set. field 46.

The area information field 40 indicates whether the corresponding area is a basic side area (an area where document blocks constituting a basic compound document page are arranged and where areas of the same type are prohibited from overlapping with each other, so to speak, an opaque area) or a transparent area (a pond). A first area type field 51 indicating which type of area the corresponding area is (an area that is allowed to overlap with another area), and which type of document block the corresponding area is, such as a text 1 table, graph, figure, image, etc. a second area type field 52 indicating whether the area is used for arranging the area; an area ID number field 53 in which an area ID number (area identification number) for identifying the area is set; As shown in FIG. 3, the position information field 54 is specified by the area start position Xs, Ys (coordinates of the upper left corner) and the size Lx (horizontal length), Ly (vertical length). , an area pamphlet in which a buffer pointer or area 1 indicating the storage position in the area buffer 18 of the document block placed in the corresponding area is set. pointer field 56
It has

Area ID numbers are assigned from O to area creation types.

Next, the operation of one embodiment of the present invention will be explained with reference to the flowchart in FIG. 4 and the operation explanatory diagrams in FIGS. 5 and 6.

In this example, if both the basic side area and the transparent area that are independently assigned to the basic compound document page are created,
In the normal state, the transparent area is displayed on the screen superimposed on the basic compound document page. The transparent area is given the ability to function as cellophane. Therefore, by creating a sentence block such as a figure in this transparent mR and displaying the transparent #4 area in which this document block has been created superimposed on the basic compound document page as described above, it is possible to display the text on the display screen. Compound documents can be created.

Now, on the display monitor 32, as shown in FIG. 5(b), a viewport for displaying documents (hereinafter referred to as document view)
It is assumed that basic temporal l7iB and transparent region C are displayed superimposed through A.

Furthermore, the midpoints and four vertices of the four sides of the transparent area C are areas that the pirate C is currently processing (processing target area, current area), as shown in FIG. 5(b). A square identification mark (this is called a handle mark) indicating the following shall be attached.

At the time of mouth, the area management table 16 is in the middle of processing! 1ilD
The area ID number of the transparent area [C is set in the number field 46. It is also assumed that a menu bar consisting of various menus including ``area operations'' is displayed at the top of the display screen of the display monitor 32.

In the above state, from the transparent area C to the basic side area B1.
: If you want to move the process, that is, move the processing target area to the transparent area C.
If the user wants to switch from the basic side area B to the basic side area B, the user should press mouse 2
4, move the mouse cursor to "Jl19 Works" on the menu bar and press the left button 26 of the mouse 24. This state is determined by the input interface 30 when the internal bus 38
The control processor 10 is notified at time t1.

When the sub-blade processor 10 detects that the left button 26 of the mouse 24 has been pressed while pointing to the area operation button on the menu bar based on the notification from the input interface 30, it first performs the area operation shown in FIG. Pull-down menu 6
0 is displayed on the display monitor 32 (step Si). In this state, the user operates the mouse 24 while holding down the left button 26 of the mouse 24 to move the mouse cursor to a desired menu item (here, "area switching") in the pull-down menu 60.

The control processor 10 causes the mouse cursor to move to a pull-down menu 60 when the left button 26 of the mouse 24 is pressed.
If it is within the range, the menu item pointed to by the mouse cursor (in this case, "Area Switch") is displayed in reverse video (steps 82 to 84). The user releases the left button 26 of the mouse 24 if the highlighted menu item is the desired item. This status is notified to the sub-processor 10 via the input interface 30. Thereby, the control processor 10 detects that the left button 26 of the mouse 24 has been released (step S2).

Control] When the processor 10 detects that the left button 26 of the mouse 24 has been released, it selects the highlighted menu item (step S5) and erases the pull-down menu 60 (step S6). Next, the control processor 10 checks whether the selected menu item, that is, the menu item specified by the user, is "area switching" (step S7). Check (step S
8). The details of this step S8 are as follows.

The control processor 10 retrieves the area ID number set in the vA area D number field 46 being processed in the area management table 16 in the memory 12 . Next, control processor 1
0 is the area information field 40 of the area management table 16
(Area ID number field 53 within) is sequentially searched,
The area information field 40 in which the same ID number as the area ID number extracted above is set is detected. That is, the control processor 10 searches for the area information field 40 in which area information of the area currently being processed is set. Then, the sub-surface processor 10 refers to the region relation insertion field 51 of the region information field 40 and determines whether the corresponding region (the region currently being processed) is a transparent region.

Now, in the case of FIG. 5(b) where the area currently being processed is the transparent area C as described above, the determination in step S8 is Y.
It becomes ES. In this case, the control processor 10 controls the center P of the document view A shown in FIG.
Find the intersection point P of the line segment (diagonal line) connecting the upper left and lower right ends of and the line segment (diagonal line) connecting the upper left and upper right ends of (
Step 39). Next, the sub-processor 10 sets the area information number i to 1 (step 510). Then, the control processor 10 refers to the i-th area information field 40 in the area management table 1G, and places the center P (point P) of the document view A in the area indicated by the position information set in the position information field 54. Check whether exists or not (
Step 511). However, if a transparent area is indicated by the area type field 51 of the information field 40, the above determination using the position information set in the position information field 54 is omitted, and the P point is
It is determined that the number does not exist within 4.

If (the area specified by the first area information field/10 is a transparent area, or) the i-th area IJ! If point P does not exist within the area specified by the information field 4o (even if the area is the basic side area), the control processor 10 determines that this area is not the user-specified processing target area, The area number @i is incremented by one (step 512). The control processor 10 then updates the area information field 4 of the new area number in the area management table 16.
0, the next area information field 40 is referred to, and the above step S11 is executed again.

On the other hand, the target #4 area specified by the i-th area information field 40 is the basic side area, and P
If a point exists, the control processor 10 determines that this area is a new processing target area, and changes the settings of the area ID number field 46 in progress in the area management table 16 to the i-th area information field. After updating the setting contents (area ID number) of item 40 [10 number field 53], the process moves to this area (step 513). That is, when the transparent area C is being processed and the area switching parameter is specified, the control processor 10 selects the basic side illumination Ij! where the center P of the document view A is located in the basic side area! <Here, the process is moved to the basic area B). At this time, the control processor 10
As shown in FIG. 5(a), handle marks are added to the midpoints and four vertices of the four sides of the newly processed area (basic side illumination ViB here), and the display processor 36 is displayed on the display monitor 32. In addition,
The handle mark that has been added to the transparent area tiffc, which has been the target of processing, is erased.

Now, in the state shown in FIG. 5(a) where the 18 processing target area has been switched from the transparent area C to the basic side area B as described above, if the basic side area B is used as a text area, for example,
You can create and edit sentences targeting the basic area B.

Next, when the area currently being processed is the basic side area B as shown in FIG. To,
A case where "area switching" is specified will be explained. In this case, since the area being processed is the basic side area B, the determination in step S8 is No. The determination in step S8 is N.
o, the control processor 10 uses the area management table 16
Transparent fAv by searching the area type field 51
The area information field 40 in which c is shown is detected, and the processing area ID number field 4 of the area management table 16 is detected.
6 in the detected area information field 40.
Setting contents of the area ID number field 53 (area ID
After updating to the number), the process moves to this area (step 314). In other words, the control processor 10 selects "area switching" when the basic side area (here, the basic side I7J, d) is being processed. Then, the process moves to the transparent area C. At this time, the control processor 10, as shown in FIG. 5(b),
Handle marks are added to the midpoints and four vertices of the four sides of the transparent area C that is newly targeted for processing. In addition, the basic ll! that has been processed so far! ++ The handle mark added to g area B is deleted.

Now, as described above, the processing target area is the basic side #4 area B
In the state shown in FIG. 5(b) where the switch has been made from the transparent area C to the transparent area C, if the transparent area C is used, for example, in the figure @ area, a figure targeting the transparent area C can be created, and the basic side area B You can also freely draw borders to correspond to the text inside.

In the above embodiment, the area information field 40 of the corresponding area is updated using the area ID number set in the area ID number field 46 of the area management table 16.
, and refer to the area type field 51 to select the corresponding Wf.
Although it has been explained that it is determined whether area a is a transparent area or not, for example, it is also possible to set a processing area type identification flag indicating whether or not the area currently being processed is a transparent area (or a basic side area). The flag may be prepared in a predetermined area of the memory 12, and the area being processed may be determined by referring to this flag. In this case, it goes without saying that it is necessary to invert the state of the processing area type identification flag in response to switching of the processing target area.

In addition, in the above embodiment, when "'\4vj, switch" is specified while a transparent area is the processing target, processing is transferred to the basic side fi[ to which the center of the document view belongs]. As explained above, the process may be moved to the basic mrl area to which the mouse cursor position belongs.Also, the process may be moved to the basic side area where the center of the document view normally falls, and when the right button 28 of the mouse 24 is pressed. In this case, it is also possible to move the processing to the basic side wAIj! to which the mouse cursor position belongs.Furthermore, in the above embodiment,
Although the case where the transparent area is one layer has been described, the present invention can also be applied to the case where a plurality of transparent areas are overlapped many times on a basic compound document page. In this case, transparent area selection is required to move the processing target area from the basic side area to the transparent area, but for example, each time the right button 28 of the mouse 24 is pressed, the transparent area is moved in a certain order (for example, in order of ID number). All you have to do is switch it.

[Effect of the invention] As detailed above, according to the present invention, the first type of #
By superimposing and displaying the transparent area (document blocks placed on) on the basic side area (basic text page consisting of various document blocks placed on) of 4Ia, it is possible to display the target compound document page. Since you can see the print image on the display screen, you can create compound document pages using transparent areas.

Improved editing efficiency. Also according to this invention.

With the basic side area and transparent area displayed superimposed, you can move from the basic side area to the transparent area, or from the transparent area to the basic (
! Since processing can be immediately transferred to the 11 area without multiple operations, the efficiency of creating and editing a compound document page using transparent areas is further improved.
