Abstract

PURPOSE:To secure the consistency of each object graphic and to improve the graphic generation efficiency by providing a selection table for setting a mutual relation of subordination and independence between the object graphics, and allowing it to correspond to an input/output instruction from a control means. CONSTITUTION:In the case an enlarged view of an object graphic displayed on a first CRT graphic display device 7 is displayed on an n-th CRT graphic display device 8, image data of the object graphic stored in a storage device 1 is loaded and subjected to enlargement processing by a CPU 4, and thereafter, delivered to an input/output channel 6. Simultaneously therewith, a selection table 10 which sets in advance the CRT graphic display device is referred to, and image data of the object graphic after the enlargement processing is outputted a designated n-th display device 8. In such a way, the consistency of each object graphic is secured, a miss in the course of graphic processing is eliminated, and the graphic generation efficiency can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphic display device, and in particular to a graphic database and a means for preventing concealment of a target graphic display due to an increase in transmission information, and a means for displaying and subordinating target graphics. independence and
This invention relates to graphical display that ensures consistency.

[Conventional technology]

In a conventional graphic display, for example, a CAD device, for example.

As described in Japanese Unexamined Patent Publication No. 62-219070, independent target figures and target characters can be simultaneously displayed on the same display means by generating several figure fields, viewports, and windows. I was going. However, until now, no consideration has been given to hiding or reducing the size of target graphics and characters due to the overlapping of graphic fields, viewports, and windows.

[Problem to be solved by the invention]

In the case of windows or viewports existing on the same display screen as in the above-mentioned conventional technology, for example, when changing or modifying the first target figure by enlarging or reducing the position specified by the operator, the operator Or, the viewboard was opened and the changed or modified Nth target figure was displayed on the window or viewboard. This method has the problem that, depending on the physical size, position, and total number of the windows or viewports, the first target figure may be hidden in whole or in part by overlapping with the window, and each There are problems in that the graphics become absolutely small and that the data input area is limited due to the increase in the amount of information to be transmitted that is displayed on the same display screen.

SUMMARY OF THE INVENTION An object of the present invention is to provide a graphic display device that eliminates the above-mentioned hiding of target graphics by the window or viewport and alleviates restrictions on the data input/output area.

[Means to solve the problem]

In order to achieve the above object, at least two or more display means are connected via an input/output channel, and image data is addressed to any display means through the input/output channel. Further, by providing a selection table for setting dependent and independent relationships with the target figure displayed on the first display means, and by associating input/output commands from the control means with the selection table, The correlation can be predefined for N display means.

[Effect]

In such a configuration, the target graphic and the transmission information on the same display screen can be set on the n-th display means. Furthermore, since the n-th display means specified by the operator and the N-th target figure can be switched to a dependent or independent relationship, consistency between the target figures is guaranteed, and the operator can eliminate mistakes during figure processing. Figure generation efficiency can be improved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

Figure 1 shows the system configuration diagram.

1 is a storage device for storing image data, 2 is a keyboard for inputting data or commands, 3 is a pointing device, and 4 is a main controller. Also,
An input/output channel 6 is connected between the graphics processor 5 and a plurality of CRT graphics display devices 7-9.

With this configuration, for example, when displaying an enlarged view of the target figure 1 displayed on the first CRT graphics display device 7 on the n-th CRT graphics display device 8, the target figure stored in the storage device 1 is The image data of figure 1 is the main control bag! After being loaded and enlarged by 4, it is passed to the input/output channel 6. At the same time, the selection table 10 in which CRT graphic display devices are set in advance is referred to, and the image data of the target figure N after the enlargement process is transferred to the specified n-th CRT graphic display device! It can be output to 8.

FIG. 2 shows the concept of the selection table 10 mentioned above. The selection table 10 consists of a group of target figures a and a group of address numbers of CRT graphic display devices,
The target figure specified by the operator is checked against the address number of the CRT graphic display device and displayed on the specified CRT.
Output to a graphic display device. With such a configuration, the target graphic can be output to a plurality of designated CRT graphic display devices, thereby preventing the target graphic from being hidden on the same screen, improving work efficiency.

FIG. 3 shows an embodiment of Section 2 of the present invention. In this embodiment, the selection table 10 includes a group of target figures a, a group of address numbers B of the CRT graphic display device, and furthermore, when one of the target figures is subjected to some processing, the other target figure is also selected in the same way. The flag group C is composed of a dependent-independent flag group C that specifies a correlation between target figures, in which a relationship that is processed in a process is defined as dependent, and a relationship in which the target figures have no relationship at all is defined as independent. With such a configuration, target graphics can be moved between CRT graphic display devices, and consistency between target graphics can be maintained.

FIG. 4 shows an embodiment of Section 3 of the present invention. In this embodiment, the selection table 10 is composed of a target graphic group a, a CRT graphic display device address number group, a dependent independent flag group C, and a command group d. When the operator inputs a processing command for the target shape,
The target graphic is outputted to the designated CRT graphic display device by comparing the address number of the CRT graphic display device corresponding to the processing command with the dependent-independent graph. In such a configuration, it is possible to move target graphics between CRT graphic display devices, and a particular CRT graphic display device can be dedicated to a command specified by an operator, so multiple CRT graphic display devices can be used. CRT graphic display devices can be treated as an integrated system, improving work efficiency.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to eliminate hidden appearance of target figures. Furthermore, consistency between the target figure and the CRT graphic display device can be ensured, and a CAD device with excellent operability can be obtained.
