Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for processing figures divided by mesh lines in a computer system that divides and manages drawings such as maps and detailed design drawings by mesh lines. It is something.

(Prior Art) In a computer system in which the original drawing 1 shown in FIG. 7 containing a large amount of information such as maps and detailed design drawings is input into a magnetic disk device 5 and managed by a computer, a wide original drawing 1 is used.
If we treat it as a processing target, for example, managing the screen display on the graphics workstation (GWS) connected to the host computer (circuit) becomes extremely complicated.
Because management is difficult, the entire original drawing 1 is divided into a certain mesh (usually rectangular) 3 by mesh lines 2, as shown in Figure 7.
The user 11 uses an input device 4 such as a digitizer or scanner to store the mesh as a basic unit in the magnetic disk drive 5, and also displays and processes the mesh. It is being done.

(Problem to be solved by the invention) However, in the conventional drawing processing method described in 1.
Since the figures divided by (mesh 3) are treated as separate figures, the following problems arise.

■ When moving or deleting a figure such as a house divided by the mesh line 2, the user 11 must always keep in mind that the figure straddles the mesh, Similar processing must be performed for

If necessary processing is omitted, the drawing as a whole will be incomplete.

■ In a mesh-based drawing management system, when manually inputting drawings to a computer as information, it is basically performed at the mesh level, but when the figures divided by the mesh are manually input separately, the input device 4 (digitizer, scanner device, etc.) ) Due to errors, etc., the joint that spans the mesh may be slightly misaligned.

For this reason, when displaying multiple adjacent meshes on one screen or outputting multiple meshes using a plotter device, etc., the figure will be discontinuous at the mesh lines, so after inputting the drawing, correct the joint parts. However, it is a difficult task to consider the figures cut by the mesh not as the entire figure (for example, a circle, polygon, etc.) but as a single line-tree and to correct this.

■ Generally, attribute information is given to the figures in Drawing-1-.

For example, the attributes of a house shape include information such as residents' names, family structure, and telephone numbers. To display this attribute information on GWS, first display the drawing, select the desired shape with the digitizer cursor, stylus pen, etc., and specify (
(big) and reads the attribute information of that figure from the host computer and displays it.

However, the figures divided by the mesh have the same attributes redundantly for each divided figure, which must be managed, and it is difficult to modify the attribute information when the attributes are changed.

The object of the present invention has been made in view of these points, and it is an object of the present invention to solve the problem 1 by making it possible to collectively manage figures spanning meshes.

=3 (Problems to be Solved by the Invention) In order to solve the problem and achieve the purpose of the present invention, in a computer system that manages drawings using meshes, the present invention provides a representation for multiple figures divided by mesh lines. It has a figure information table that has information defined separately for the parent figure and other child figures, and a parent and child management table that manages which parent and child figures are the same figure. When various graphic processing is specified for a part of a graphic, the parent graphic of the specified graphic is obtained from the graphic information table, information that only the parent graphic has is obtained as a representative, and the parent/child management is performed. The present invention is characterized in that child figures of the divided figure are obtained from the table and can be processed as the entire original figure before being divided.

(Function) The present invention has information that defines a plurality of figures divided by mesh lines into representative figures (hereinafter referred to as parent figures) and other figures (hereinafter referred to as child figures). It has a figure information table and a parent-child management table that manages which parent and child figures are the same.Based on this, just by specifying a part of the divided figure, the entire original figure before division is processed. It is possible.

(Embodiment) FIG. 1 shows a basic configuration diagram for implementing the method of the present invention. In the figure, 6 is a figure information table, Mi (i=1, 2 .
......, n) is the mesh number of the figure, j (, j=
001,002.・=-, m) indicates the figure number. 7
is a parent-child management table that shows the relationship between Mi and j.

Reference numeral 8 denotes a mesh straddling figure processing unit, which includes a mesh straddle determining unit 81 (judging from the figure information table 6), a parent figure extracting unit 82 (extracting from the figure information table 6), and a processing target figure extracting unit 83 (extracting from the parent-child management table 7). ). 9 is a graphics workstation (GWS),
It has a digitizer 91. IO indicates each drawing and figure divided into mesh groups, and M i (mesh number)
and J (figure number) are also illustrated. In addition, 11 is GW
The user I2 of S9 is a graphic processing section.

Next, to explain the operation, when the user II displays a drawing on the GWS 9 and specifies the drawing and figure IO of the mesh group to be processed, the mesh number M1 of the specified figure and the figure number j are mesh-straddling figures. It is sent to the processing section 8.

In the mesh straddling graphic processing unit 8, a mesh straddling determining unit 81 refers to the graphic information table 6 and makes a determination.

If there is no parent-child relationship defined here, it is determined that the figure is not a mesh-straddling figure, and only the figure instructed by the user 11 is sent to the figure processing unit 12 for processing.

In addition, if the mesh straddling determining unit 81 determines that there is a parent-child relationship definition, the mesh straddling figure is determined to be a mesh straddling figure.
If it is a child figure, it is sent to the parent figure extraction section 82.

The parent figure extraction section 82 extracts parent figures Mi and J from the figure information table 6 and sends them to the processing target figure extraction section 83 . On the other hand, if the mesh straddle determining unit 81 determines that the figure is a parent figure, M1 of the parent figure is sent to the processing target figure extracting unit 3.

Then, the processing target figure extraction section 83 refers to the parent-child management table 7 from M1 and j of the designated parent figure, extracts all the figures that require graphic processing, and sends them to the figure processing section 12 for processing.
