DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a document editing apparatus, and more particularly, to a case where a document composed of a plurality of components including a graphic is edited, each component of a structured document can be edited by a user. Display hierarchically to suit the editing intent of,
The present invention relates to a document editing device capable of selecting and editing each component.

[0002]

2. Description of the Related Art Conventionally, in a document editing system for a document including a figure, in order to facilitate figure editing, a plurality of document components (hereinafter, simply referred to as elements) constituting a figure, text, and the like are used. A grouping function that collectively treats the group as one and a grouping release function that releases the grouping are provided. When a document is edited using this grouping function / grouping release function, for example, elements constituting a figure are sequentially generated, and in the process, a plurality of elements constituting the figure are grouped stepwise. Here, after grouping, when grouping is released for subsequent partial modification of the figure, the way to release the grouping is that the entire group selected for grouping release is conventionally A first method of dividing into individual components and a second method of holding each stage of grouping and sequentially returning to the state of grouping of the immediately preceding stage are used.

In such a conventional document editing system, even when the grouping function and the ungrouping function of the first method or the second method are used, a plurality of figures forming a grouped figure are used. It is not easy to select an arbitrary element individually from the elements.

Accordingly, in a document editing system having a grouping function holding grouping hierarchical structure information and a grouping canceling function, an arbitrary element constituting a figure or the like, Various methods have been proposed to select a group unit.

For example, the method proposed in the "graphic selection method" described in Japanese Patent Application Laid-Open No. Hei 5-242209 is disclosed in Japanese Patent Application Laid-Open No. 5-242209. Even if it is done, without breaking the grouping, using the information of the grouping structure,
This is a proposal of a method of changing a selection target according to the number of clicks or the click time of a selection instruction on an editing screen for performing graphic editing.

A method proposed in "Drawing Editing Apparatus" described in Japanese Patent Application Laid-Open No. Hei 5-324740 is to display an element representing a hierarchy on a screen and click on the element to select the hierarchy. This is a proposal for a method of selecting an element belonging to a lower hierarchy of. Also, JP-A-4-90065
Japanese Patent Application Laid-Open Publication No. H10-260, "Method and Apparatus for Processing Graphic Data Having Hierarchical Structure", when selecting a selection function from a menu or the like, selects only the component to be selected or clicks the component to which the component belongs. There has been proposed a method of selecting a method of selecting a target to be selected by designating the entire group.

At present, a graphic processing system based on an application program of a software product having a trade name "Adobe Illustrator", which is commercially available from Adobe, includes, among its graphic processing functions, a function of only selecting an element clicked on a selection target; A function is provided for grouping elements to form an entire group, and an element is selected by designating a selection function from a menu or the like. Here, when the function of selecting only an element is used, an arbitrary layer in the hierarchical structure of the group can be selected by the number of clicks by the number of clicks.

[0008]

However, in such a conventional method, it is difficult to visually grasp the hierarchical structure of the group in the case of grouping, and therefore, elements which are not incorporated in the hierarchical structure of the group. Choosing a unity is not easy. Therefore, there is a problem that the element selection operation cannot be performed efficiently.

That is, when selecting a group of elements that are not in the hierarchical structure of the group, it is necessary to regroup or to individually select the constituent elements to be selected. Specifically, for example, if a method of re-grouping is used, the hierarchical structure at the time of the previous grouping is lost, and if it is desired to return to the previous hierarchical structure, it is necessary to redo the grouping again.

When the method of individually selecting elements is used, the more elements to be selected, the more complicated the operation of selecting the individual elements. For example, it is difficult to select a small element or an element that partially overlaps, so it is difficult to select the element and perform an operation by enlarging it on the edit screen, or change the vertical relationship of the overlap of each element. Therefore, the operation of selecting each element must be performed. Also,
Even if a complicated selection operation is performed and the selection is made, the element group in the selected state is canceled once if another selection operation is performed. However, there is a problem that it is necessary to re-select the corresponding element from the beginning again, which takes much time and effort.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to make it easy to visually understand the structure of elements constituting a document and to construct the document. There is a need to provide a document editing apparatus that allows a user to easily select and edit an element of a structure by an operation on a display screen visually.

FIG. 3 shows the structure storage subsystem 13.
FIG. 3 is a block diagram showing the configuration of FIG. The structure storage subsystem 13 stores the structure information used in document editing for reuse. For this reason, as shown in FIG. 3, the structure storage subsystem 13 includes a structure storage unit 31 and a structure selection processing unit 3.
2, a structure registration processing unit 33, a structure switching processing unit 34, and an editing operation reflection processing unit 35.

The structure storage section 31 stores a plurality of pieces of structure information to be reused in document editing. Structure selection processing unit 32
Selects a saved structure to select a structure to be used in the editing operation. The structure registration processing unit 33 saves the displayed upper structure, or the structure selection processing unit 32

Updates the structure information by reflecting the content changed in the document editing on the structure stored here.

Next, a document editing operation by the document editing apparatus according to the present embodiment will be described with reference to a specific example. here,
A case where a pie chart is created as an example of an edited document will be described. FIG. 4 is a view showing an example of a screen of a figure editing window for document editing. As shown in FIG. 4, the figure editing window 40 includes an image display sub-window 41.
And the structure display sub-window 42 are displayed side by side. In the image display sub-window 41, an image of the pie chart graphic being created is displayed, and the structure of the corresponding pie graph graphic element is displayed in the structure display sub-window 42. That is, in the image display sub-window 41, an image display of a pie chart graphic composed of a combination of elements (graphic elements and character string elements) is displayed as it is, and correspondingly, the structure display sub-window 42 displays By the structure generation processing unit 21 of
For example, the structure of the combination of elements is displayed in a tree structure display based on the automatically generated structure information according to the order in which the elements are created or combined.

In this embodiment, a tree structure is used as a display structure. Therefore, the leaves of the tree are the elements that make up each figure, and the nodes other than the leaves are objects. As shown in FIG. 4, the top node of the tree is “T
The node of the object that represents the entire document "op" is an object node. The node of the object merely indicates the connection relationship of the elements, and thus may not have a name. To avoid this, each node of the object is given a name, and it is possible for the user to arbitrarily rename the node of this object.

As an example of the document editing operation, a graphic element is uniformly enlarged / reduced and the font of text data is changed in order to enlarge / reduce while maintaining the balance of the entire document. An example of the operation will be described as an example.

In this case, the figure editing operation is performed as shown in FIG.
First, a node 52 for forming a text object is added in the structure display sub-window 51 as shown in the upper part of FIG. The name of the node 52 is “SG1-4” from the hierarchical level of the structure and the creation order. The element T1, element T2, and element T3 of the text element are replaced with the node 52 of the text object. And
As shown in the lower part of FIG.
In FIG. 4, a new text object is set to a node name “SG1-4”, the node 52 is assigned to the top node, and the graphic object node 53 is set to the node name “SG3
-1 ". This added node 53
, The node “SG2-1” from the Top node,
The node “SG1-2” and the node “SG1-3” are replaced. Further, the node “SG3-1” of the graphic object
Is attached to the Top node.

As a result, the structure resulting from such an editing operation is as shown in the lower part of FIG. Subsequently, when the node of the object having only one lower node is deleted from such a structure, the structure becomes as shown in the upper part of FIG. Then, when the names of the nodes of the object are newly given to the nodes of the object so as not to be duplicated by the hierarchical level of the structure and the numerical values of the creation order, the names are as shown in the lower part of FIG. That is, here, the name of the node 52 changes from the node “SG1-4” to the node “SG1-3”, and the name of the node 53 changes from the node “SG3-1” to the node “SG2-1”.
It should be noted that, in order to avoid a deeper hierarchical level when the structure is changed, in the structure editing process here, a process of automatically applying a rule for deleting redundant nodes may be performed. Good.

When the editing operation of such a structure is performed, that is, when the editing operation is performed on the structure information as shown in the lower part of FIG. 6, the elements T1, T2, and T3 of the text are selected. This can be done by selecting the text object node “SG1-3”. Further, in the structure display sub-window 56, each of the three text elements of the leaf node may be directly selected. Since the branches of the structure correspond one-to-one with the lower nodes, it may be performed by selecting the branches.

In the structure display sub-window 56 shown in the lower part of FIG. 6, the elements constituting the graphic and the elements of the text are connected to different object nodes, respectively. You can now select graphic elements and text elements separately. Therefore, for example, when performing an operation by enlarging / reducing a graphic and subsequently changing the font of the text in the graphic,
Performing the editing operation, seeing the balance between the entire figure and the text, and performing the enlargement / reduction of the figure and the editing operation of changing the font can be performed in a well-balanced manner, and the fine adjustment can be performed efficiently. I can do it.

In this case, the result of the editing operation of the configuration of the figure performed in the structure display sub-window 56 is as follows:
By the processing of the structure reflection processing unit 26, the image is reflected on the display of the image display sub-window. That is, in order to reflect the change in the structure in the structure display on the image display, the display content of the image display window is changed to match the structure display of the grouped hierarchical structure.

In this embodiment, the structure modification processing is sequentially reflected on the image display every time the structure is rearranged. However, during the editing operation, the editing result is not reflected and is specially reflected. The correction based on the editing result may be reflected only when a command for reflecting the correction is executed by an instruction such as a pull-down menu. As a result, the response speed of the processing during the editing operation does not decrease.

As described above, in the figure editing window 40 (FIG. 40), there is a one-to-one correspondence between the display contents of the image display sub-window 41 and the display contents of the structure display sub-window 42. Since the structure change in the structure display is always reflected in the image display by the processing of the structure reflection processing unit 26, an instruction to select an element to be edited can be given also in the image display sub-window 41. . That is, an instruction to select a graphic area corresponding to the object node “SG1-2” displayed in the structure display sub-window 56 shown in the lower part of FIG. 6 and to select a text area corresponding to the object node “SG1-3” Can also be performed in the image display sub-window 41.

In order to avoid complicating the structure display, the structure display in the structure display window 42
It is possible to select whether to display or not display the lower hierarchy for each object node in the display content, and to hide the lower hierarchy for each object node according to the selection. With such a simple display,
It is possible to easily give an instruction to select a specific part for a complicated figure.

FIG. 7 is a view for explaining a display example of the structure by the simplified display. Structure display sub-window 7 shown in FIG.
0, the structure display subwindow 5 shown in the lower side of FIG.
In 6, the lower hierarchy of the node "SG2-1" of the displayed graphic object is not displayed, and the lower hierarchy of the node "SG1-3" of the text object is not displayed. The above-described enlargement / reduction operation can be efficiently performed by selecting an operation target object and performing an editing operation on the display of such a simple structure, thereby efficiently selecting an element to be operated. it can.

Further, as another example of a method for preventing the structure display from becoming complicated, it is also possible to display only the structure in the selected area selected in the image display sub-window. FIG. 8 is a diagram showing a display example when only the structure in the selected area is displayed by the image display sub-window. As shown in FIG. 8, in the image display sub-window 81, for example, the text “Type
In order to select and instruct the character string area of “eB”, when the pointer cursor 83 selects and instructs the area 84 surrounding the character string of the text “Type-B”, at this time, in response to the selection instruction of this area, In the structure display sub-window 82, only the structure of the element related to the character string element of the text “Type-B” is displayed. That is, in the structure display sub-window 82 in this case, the text “Type
-Type of text that is not related to the element of the string
The structure (shown by a broken line in the figure) relating to the character string element of “-A” and the character string element of the text “Type-C” is not displayed.

In the document editing, before editing the structure of the figure, the structure storage subsystem stores the structure information used in the editing. The data structure for storage is a list structure. FIG. 9 is a view for explaining the data structure of the structure information generated for the elements constituting the graphic to be edited. As shown in FIG. 9, the data structure of the structure information has a link in which information of each element constituting the figure and structure information of each object node are linked by a list structure.

According to such a data structure, the data of the element constituting the figure is composed of the element name 91 and the attribute data 92 of the entity data of the element. The configured structure information is linked by a pointer. Each object can determine the lower hierarchical structure and its individual elements by following the pointer from the Top node.
According to such a data structure, a plurality of pieces of structural information of each object node can be stored for data of one element group forming a figure. Therefore, a plurality of types of structural information are stored and stored in correspondence with a figure editing operation, and one of them can be reused to perform the editing operation efficiently.

FIG. 10 is a view for explaining a data structure when a plurality of pieces of structure information are stored for elements constituting a figure. As shown in FIG. 10, the data structure stored in the structure information storage unit includes one
The data structure of one graphic element group has a data structure in which structure information of each object node of a plurality of structure information is linked by a list structure.

As described above, since a plurality of structures are registered, even when storing the structure information, the data of the same element is used as the data constituting the figure, and the amount of data to be stored is determined by avoiding duplication. Decrease.
In this case, as shown in FIG. 10, at the time of saving, a plurality of Top nodes are automatically numbered in the order in which they are saved, or the user assigns a unique name to each of the saved nodes, so that any saved structure can be saved. Distinguish. If the structure information that has been saved is reused by the editing operation and it has been changed, a dialog message on the system side indicates whether to overwrite or save as a different name according to the dialog message on the system side. Choose.

To select a structure previously saved for editing, a pull-down menu using a graphical user interface process is used to list the number of the save order or the name of the structure assigned by the user in a list. Choose from among them. When one structure is selected by the user's instruction, the data (structure information) of the structure currently displayed in the structure display sub-window is deleted, and the object node of the selected structure information is traced from the top node. Generates a tree structure, and displays the generated tree structure in the structure display subwindow.

When the structure displayed in the structure display sub-window 42 shown in FIG. 4 is selected, the data structure of a plurality of structure information shown in FIG. Follow the link destination (dashed line) of the node to generate and display a tree structure. When displaying the edited structure as shown in the lower part of FIG. 6, the link destination (solid line) of each object node is traced from the top node of “Top: 2” to generate a tree structure. indicate. In this manner, when the structure display is switched, the selected structure is reflected on the image display by the structure reflection processing unit 26 in response to the switching.

When the editing process is performed on the graphic, the elements constituting the graphic to which the editing process is applied are searched from the stored structure information, and the attribute values of the changed element are corrected. If unsaved elements are added to the saved structure information, and if the saved structure is consistent,
The structure that is currently being edited is added as it is, and if there is a contradiction, the structure of only the additional components is added to the saved structure.

FIG. 11 is a diagram for explaining an example of processing for changing a data structure by updating structure information when a graphic element is added. For example, in the structure display window 56 shown in the lower part of FIG.
As shown in (a), a new element 11
1 is added and reflected in the stored structure information.
1 (b) is obtained. That is, in the list of components,
New element data 112 corresponding to the added element 111
And reflect it in the structural information.

In this case, since the element 111 intersects the elliptical graphic element (E5) and the circular graphic element (E9),
These two elements are regarded as the same object. In the structure of the solid line, the two elements E5 and E9 belong to the same object node "SG2-1".
Is the link 11 from the object node “SG2-1”.
3 is provided. However, in the dashed structure, the two elements E5 and E9 each have a different object node "S
G1-2 "and" Top: 1 ", the structure is added to the structure only with the added element 111, and the link from the" Top: 1 "node to the link 1
14 is formed.

As described above, in the present embodiment, a structure is generated for each figure editing process, editing is performed using the structure information, and the structure information used in the editing is reused. Since the graphic information is saved, when the graphic editing using the structural information is performed, for example, when a graphic element is added or deleted, a process of reflecting the edited content on the stored structural information is performed. That is, the contents of the editing operation are reflected in the stored structure information. The processing may be collectively reflected when the structure information is stored, when the structure information is selected, when the graphic editing processing is ended, or the like.

FIG. 12 is a block diagram showing a system configuration when the document editing apparatus of the present invention is applied to a computer system. In this system configuration, the monitor device 1
Each of the system elements of the present invention is applied to a computer system including a computer 21, a mouse / keyboard input device 122, a system device main body 123, a storage device 124, and an external storage device 125. That is, the input device 15 for performing input processing is associated with the mouse / keyboard input device 122, and the display device 14 for performing display processing of image display and structure display is associated with the monitor device 121.
The system device main body (CPU) 123 incorporates the document editing subsystem 11, the structure recombination subsystem 12, and the structure storage subsystem 13. Also, the storage device 124
, A work storage area used in this system is secured. For this reason, a memory area 126 for holding the correspondence and a memory 127 for storing the structure are provided. Further, the external storage device 125 provides a disk area for storing structural information to be reused.

[0047]

As described above, according to the document editing apparatus of the present invention, the editing operation is performed using the structure information in the editing process of document creation, so that the structure of the object can be easily visually recognized. Become. Further, since this structure can be edited, a hierarchical structure suitable for a user's editing intention, which cannot be sufficiently expressed by structuring the automatically generated structure, can be easily created by changing the structure. Further, by performing the selection operation on the structure display based on the structure information created here, it is possible to reduce mistakes in selecting the element to be edited. By saving the structure information used in the editing, a structure suitable for the editing operation intended by the user can be reused in the editing process by saving. Also in this case, the selection can be made immediately by using the graphical user interface, and the editing work can be made more efficient.
