2. Description of the Related Art Generally, when a graphic processing system is used to create various graphics, a creator uses a keyboard to sequentially draw graphic elements such as straight lines, curves, and circles while watching a display screen of a CRT display device. So I will enter the key. Then, a desired graphic is obtained by combining these graphic image elements.

Even in the case of inputting the one graphic element, the type of graphic element such as a straight line, a curved line, and a circle,
It is necessary to enter data that specifies each graphic element. For example, in the case of a straight line, the coordinates of the starting point and the coordinates of the ending point need to be input, and in the case of a circle, the coordinates of the center and the radius must be input.

When performing an editing process such as correcting, deleting, or adding a part of the graphic thus created, the graphic of the part to be edited is constructed as described above. Since it is necessary to specify each graphic element on the display screen, each data for specifying each graphic element is keyed in by the same operation as when creating the graphic. Then, when the corresponding graphic element is specified, the graphic type is actually edited as intended by the creator by designating the edit type such as deletion, addition, and change by key operation.

[0005]

However, even in the graphic processing system for performing the editing process on the created graphic by the above-mentioned procedure, there are still the following problems to be solved.

That is, generally, the finally created figure is a combination of a large number of unit figures such as rectangles, triangles, trapezoids, and cylinders, and when one figure includes a large number of identical unit figures. There are many.

Therefore, in the case of performing the above-described editing for one type of unit figure in a figure constituted by combining a plurality of unit figures having the same shape as described above, the above-mentioned complicated same editing is performed. The device needs to be run repeatedly. Since the task of sequentially designating each of the graphic elements is very complicated for the graphic creator, there is a concern that the efficiency of graphic editing work will be significantly reduced.
Further, even if the same editing process is intended to be carried out, there is a concern that human error may occur due to misaligned graphic editing due to incorrect input of coordinates. Further, the graphic editor needs to be familiar with the functions of the graphic processing system and complicated handling operations.

The present invention has been made in view of the above circumstances. For example, a basic graphic corresponding to a unit graphic is defined, and an edit basic graphic to which editing attributes such as addition and deletion are added to the basic graphic is added. It is an object of the present invention to provide a graphic editing device of a graphic processing system which can simplify the editing work for the same editing content by creating and storing it and can greatly improve the work efficiency of the whole graphic creating work.

[0009]

In order to solve the above problems, the present invention provides a graphic editing apparatus of a graphic processing system for editing a created graphic in a graphic processing system for creating and editing a graphic,

Basic figure defining means for defining a basic figure for editing, and an editing basic figure for creating an editing basic figure with an editing attribute added to each defined basic figure Creating means, figure storing means for storing the created editing basic figure, figure reading means for reading out the editing basic figure corresponding to the portion to be edited when editing the created figure from the figure storing means, and reading An edit attribute determining means for determining the edit attribute of the edited basic graphic and a graphic editing means for editing the portion of the graphic to be edited corresponding to the edit basic graphic according to the edit attribute.

[0011]

In the graphic editing device of the graphic processing system configured as described above, the graphic creator or the graphic editor first corresponds to the unit graphic such as a rectangle, a circle or a triangle that constitutes the created graphic. , Define basic figures respectively. Then, when performing an editing process such as addition and deletion on this basic figure, an editing basic figure to which the editing attributes such as addition and deletion are added is created and stored in the figure storage unit. deep.

When a part of the unit graphic forming the created graphic is edited, the editing basic graphic corresponding to the part is read out from the graphic storage unit and the position is adjusted on the display screen. When an editing command is input later, the corresponding portion is automatically edited based on the editing basic figure.

As described above, since the editing work for editing each unit figure is simplified, the editing work efficiency in the case of editing a figure in which a large number of identical unit figures are incorporated is greatly improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a graphic processing system incorporating the graphic editing apparatus of the embodiment. The figure processing system 1 is composed of a kind of computer, and is roughly divided into a figure creating section 2 for creating a figure and a figure editing apparatus 3 for editing a created figure, as shown in the figure.
And a man-machine device 4 for displaying a drawing being created and a drawing being edited and allowing the figure creator or figure editor to interactively input various data and operation commands.

Further, as shown in the figure, the figure editing device 3 includes a basic figure defining section 5, an editing basic figure creating section 6, and
Graphic storage unit 7, graphic reading unit 8, and editing attribute determination unit 9
And the graphic editing unit 10. Next, the operation of each unit will be described step by step.

In the figure creating unit 2, the figure creator uses the keyboard to sequentially order graphical elements such as straight lines, curves, and circles in the man-machine device 4 in an interactive manner while looking at the display screen of the CRT display device. Enter. Then, a desired graphic is obtained by combining these graphic image elements.

In the basic figure defining section 5, in the process of the figure creator sequentially creating desired figures using the man-machine device in the figure creating section 2, a rectangle as shown in FIG. , Unit figures such as triangles, trapezoids, and cylinders 11
As shown in FIG. 3 (a), when is created. A basic figure 12 is defined by taking out a portion to be edited in the unit figure 11. Specifically, the basic figure shown in FIG. 3A is created on the display screen by the conventional method of sequentially specifying the figure elements.

In the basic figure defining section 5, it is not always necessary to create the basic figure 12 for editing by using the unit figure 11 created in the figure creating process in the figure creating section 2, and the figure creating section 2 The basic graphic 12 may be independently defined regardless of the creation operation of the above. That is,
The basic graphic 12 may be created before starting the graphic creation work in the graphic creating unit 2.

Next, in the editing basic figure creating section 6,
According to the editing policy, the figure editor may edit the basic figure 12 defined by the basic figure defining unit 5 as shown in FIG. Editing basic figure 1 to which each editing attribute 13b is added
3 is created by the interactive work using the man-machine device 4. In this case, each of the diagrams 13a and 13
The designation work of b is the same as the conventional method of designating the start point and the end point.

Furthermore, the addition diagram 13a and the deletion diagram 13
With only b, the figure creator cannot know which part of the basic figure 12 shown in FIG. 3 (a) the addition diagram 13a and the deletion diagram 13b correspond to. A temporary display graphic 13c shown by a solid line that is not involved is also created at the same time.

The editing basic graphic 13 thus created is temporarily stored in the graphic recording unit 7 constituted by, for example, a magnetic disk device (HDD) or the like. Therefore, the basic graphic 1 corresponding to each unit graphic 11 is stored in the graphic recording section 7.
A plurality of types of editing basic figures 13 are stored for each 2.

When it is necessary to edit a part of the graphic in the process of creating the graphic in the graphic creating unit 2,
The figure creator uses the figure reading unit 8 to read the man-machine device 4
Is used to read the editing basic graphic 13 corresponding to the unit graphic 11 of the portion to be edited from the graphic storage unit 7 and display it on the display screen on which the graphic already created is displayed. Then, when the corresponding editing basic figure 13 is displayed, the corresponding editing basic figure 1 is operated by a key operation on the keyboard.
3 is aligned with the edit target portion of the created drawing.

When an edit command is input by, for example, a key operation, the edit attribute determination unit 9 is activated, and the portion of the created drawing overlapping the edit basic graphic 13 corresponds to the delete line 13b of the edit basic graphic. Or temporary display graphic 1
The edit attribute corresponding to 3c is determined. In the case of the additional line figure 13a, it is not necessary to compare it with the created drawing. When the edit attribute of the portion to be edited in the created drawing is determined, the graphic editing unit 10 is activated and the edit target portion is edited according to the edit attribute.

A specific example will be described with reference to FIG. On the display screen of the man-machine device 4, when the editing basic figure 13 is superimposed on the unit figure 11 which is the object of the created drawing, the part corresponding to the deletion line figure 13b of the editing basic figure 13 in the unit figure 11 is deleted. For example, a straight line graphic is added at a position corresponding to the additional line graphic 13a. As a result, as shown in the figure, the edited figure 14 in which the lower right triangular portion of the unit figure 11 is deleted is obtained.

The basic figure defining section 5 and the editing basic figure creating section 6 are not limited to the editing basic figure shown in FIG. 5 in which a part of the rectangle shown in FIG. 3 is deleted in a triangular shape. As described above, it is possible to create the editing basic graphic 13 that instructs the editing to delete a part of it into various shapes. Also,
As shown in FIG. 5B, it is possible to create the editing basic graphic 13 that is composed of only the additional graphic 13a without the delete graphic 13b.

According to the figure editing apparatus of the figure processing system thus constructed, the figure creating section 2 can edit the part to be edited in advance in the drawing creating process before starting the drawing creating work. A large number of editing basic figures 13 as shown in FIGS. 3 and 5 for the corresponding unit figure 11.
Is created and stored in the graphic storage unit 7.

Then, in the case of actually creating a graphic, when it becomes necessary to edit, the editing basic graphic 13 corresponding to the portion and having a desired editing attribute is read from the graphic storage unit 7. , The corresponding portion is edited by simply overlapping it on the display screen and pressing the edit execution key.

In this way, by storing a large number of editing basic figures 13 in the figure storage unit 7 in the form of a database, when editing becomes necessary at the time of creating a figure, it is added as in the conventional method. Figure. There is no need to perform complicated operations such as inputting the starting point and the ending point of each graphic element as in the case of creating a deleted graphic in general. In particular, it is possible to expect a significant improvement in the efficiency of editing work in the work of creating machining drawings for attaching a large number of identical parts such as setscrews and gears in machine drawings.

Further, once a large number of editing unit graphics 13 are stored in the graphic storage unit 7 as a database, for example, when editing a created graphic, the corresponding editing basic graphic 13 is read out and the editing target portion is read. Since it is only necessary to align the position with, it is possible for a person who is unfamiliar with the operation of the graphic processing system to easily perform editing work. Further, since it is not necessary to input the coordinates each time, when the same editing process is performed on a plurality of parts, the edited figures will not be misaligned due to an artificial input error or the like. As a result, editing quality can be improved.

[0031]

As described above, according to the graphic editing apparatus of the present invention, for example, a basic graphic corresponding to a unit graphic forming a graphic is defined, and edit attributes such as addition and deletion are added to the basic graphic. An edit basic figure is created and stored in memory, and the figure is automatically edited using the stored edit basic figure. Therefore, the editing work for the same editing content can be greatly simplified, and the work efficiency of the whole graphic creation work in the whole graphic processing system can be greatly improved.
