Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic creation device installed as one function of a document creation device, for example.

[0002]

2. Description of the Related Art Conventionally, a graphic creation function for creating a graphic or the like has been used as one function of a document creation apparatus, for example.

That is, the operation mode of the document creating apparatus is designated and set to the figure creating mode, and the figure creating program is started. Next, after selecting the desired figure type (straight line, curved line, polygonal line, circle, ellipse, etc.) to draw, the type and thickness (line type) of the figure line, etc., move the cursor (eg crosshair cursor) Then, the graphic drawing range (drawing start position and drawing end position) on the display screen is specified. Then, a desired figure pattern is displayed corresponding to the figure drawing range designated by the cursor.

In this way, for example, a road on a map (a road figure, that is, a width line figure consisting of two lines facing each other with a constant width) is combined with a figure type (line figure) of a straight line or a curve. By doing so, the building, the mark, etc. can be drawn by combining other graphic types such as a square, a circle, and an ellipse.

Therefore, instead of drawing a map by simply combining graphic types, various map symbols are stored in advance as dedicated graphic patterns, and the stored graphic patterns of the various map symbols are read out to be arbitrarily selected. It is conceivable to provide a "map creation function" that draws a map more easily by adding and editing the above-mentioned processing independently of the above-mentioned graphic creation function.

Considering such a map creation function, various map symbols have unique "meaning" and "attributes" unlike simple graphic patterns. For example, stations, tunnels, bridges, etc. for railroad tracks. Also, traffic signals for roads, gas stations, parking lots, bridges, etc. have a close relationship, and if this relationship is computerized, it should be possible to use it to create maps more efficiently.

[0007]

However, there is no conventional document creating apparatus or the like equipped with a dedicated map creating function in addition to the normal figure creating function. Therefore, various map symbols are stored as a graphic pattern, and None of them had the idea of using "attributes" to help create maps.

The present invention has been made in view of the above circumstances, and an object thereof is to have a dedicated map creating function instead of an ordinary graphic creating function, and to establish an attribute relationship of various map symbols. An object of the present invention is to provide a map creation device capable of efficiently drawing and creating a map.

[0009]

That is, according to the present invention, a plurality of map graphic data having attribute information indicating a master-slave relationship is stored in a storage unit, and the "master" attribute information stored in this storage unit is stored. When editing such as copying, moving, or deleting the map graphic data having the above is specified, other map graphic data having the attribute information of “subordinate” to the specified map graphic data is retrieved from the storage unit and obtained. The other map graphic data and the specified map graphic data are collectively edited, and the editing operation of the other map graphic data attached to the specified map graphic data can be omitted. It is possible to draw and create maps efficiently.

Further, according to the present invention, a plurality of map graphic data having attribute information indicating a master-slave relationship and position information on a map are stored in a storage unit, and the "master" attribute information stored in the storage unit is stored. Copy, move to map figure data,
Other map graphic data that has "subordinate" attribute information for the specified map graphic data when editing such as deletion is specified and whose position information is within the specific range of the position information of the map graphic data The above-mentioned storage unit is searched, and the obtained other map graphic data and the specified map graphic data are collectively edited. Since it is possible to omit the editing operation of the map graphic data of, the map can be efficiently drawn and created.

Ends the process.

When a part of the map figure is moved as a means of editing the map shown in FIG. 3, the original range to be moved after operating the "move" key of the keyboard 11, for example, the figure A rectangular area surrounding the inner railway track 31 is designated by the cursor keys, and then the "conversion / next candidate" key is operated to determine the area. Next, when the position of the destination of movement is designated by the cursor key, the movement is executed. In this case, in FIG. 2, the map data display control unit 16 first determines from the attribute information whether or not there is map data attached to the railroad track 31 within the original range of movement as the editing means ( Step A1).

In this case, the map data of the stations 32 and the tunnels 34 having the attribute information of the relationship of “main” and “subordinate” with the railroad track 31 in the rectangular area surrounding the railroad track 31 partially overlap the position information. Therefore, it is determined that there is accompanying data, and it is next determined whether the editing instruction content is copy, move, or delete (step A2).

Since the content of the editing instruction is to move,
Then, in the above step A1, it is determined that there is accompanying data, and the accompanying map data, here, the station 32 and the tunnel 34.
The new railroad track 31 'and the station 3 are moved together with the map data of the railroad track 31 and the position information of each map data is rewritten to move the distance B as shown in FIG.
2 ', the display data of tunnel 34' is updated and created
The display is output in step 2 (step A4), and the processing in FIG. 2 is completed.

Further, in the case of deleting a part of the map figure as a means of editing the map shown in FIG. 3, a range to be moved after operating the "delete" key of the keyboard 11, for example, in the figure. When the rectangular range surrounding the river 40 is designated by the cursor key and the “conversion / next candidate” key is subsequently operated to determine the range, the deletion is executed. In this case, in FIG. 2, the map data display control unit 16 first determines whether or not there is map data associated with the river 40 within the range to be deleted as the editing means, based on the attribute information (step A1). ..

In this case, the river within the rectangular area surrounding the river 40
Bridge 4 with 40 as "master" and attribute information of "subordinate" relationship
Since the map data of 1 and 41 partially overlap the position information, it is determined that there is accompanying data, and it is next determined whether the editing instruction content is copy, move, or delete (step A2).

Since the content of the editing instruction is to delete,
Next, in step A1, the accompanying map data determined to be associated data, here, the map data of the bridges 41, 41 is deleted together with the map data of the river 40 as shown in FIG. 6 (step A5). The process of FIG. 2 is terminated.

In the above embodiment, examples of "road" and "guidance line", "railroad track" and "station" and "tunnel", and "river and" bridge "as map data having attribute information of master-slave relationship Although shown, it is not limited to these. Also,
In the above embodiment, the case of the graphic display has been described, but the same can be applied to the case of printing.
