Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a graphic display system, and more particularly to a graphic display system that performs graphic processing using a command input type interactive format to manage the display of graphics.

Prior Art Conventionally, in this type of system, an input command is analyzed, and the analysis result is displayed as a graphic on a graphic display device.

The conventional graphic display method described above is capable of displaying a graphic in response to an input command and updating the displayed graphic from an operation performed by an input device of the graphic display device, but does not have a function to reversely generate a command for that operation. Therefore, the input command cannot be updated. Therefore, even if operations such as adding or deleting the displayed figures on the figure display device are performed, the input commands are not updated as they are, and as a result, the input commands cannot be matched with the displayed figures, making it difficult to manage or redisplay the figures. There are drawbacks.

Purpose of the Invention The purpose of the present invention is to update the contents of the command input file not only by registering commands in the command input file but also by adding, deleting, modifying, etc. graphics on the graphic display device. An object of the present invention is to provide a graphic display system that accurately manages the correspondence between commands and graphics.

Structure of the Invention A graphic display system according to the present invention includes a command input file and command analysis means for analyzing commands registered in the command input file, and a graphic display system that displays a graphic based on the analysis result. The display system is a correspondence table that associates the identification number of the display figure with the instruction number of the command corresponding to the display figure, in order to express the correspondence between the display figure and the command registered in the command input file. a means for generating an additional figure generation command in response to a figure adding operation on the figure display device; and a means for associating the instruction number of the additional figure generation command with the identification number of this additional figure and storing the same in the correspondence table. means for registering the additional figure generation command in the command input file at the same time as writing, and means for searching the identification number of the deleted figure from the correspondence table in response to a figure cancellation operation on the figure display device, and searching for the identification number of the deleted figure from the correspondence table. and means for deleting an instruction having an instruction number corresponding to the instruction input file from the instruction input file.

Example Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of the present invention. 1 is an instruction input file that stores input instructions, 2 is an input control unit that checks the authenticity of the input instructions and controls input/output with the instruction input file, and 3 is an input control unit that stores the input instructions. This is a control unit that sends the data to the graphic display device 5 or receives it from the graphic display device 5 and analyzes it. 31 is a control unit that analyzes input commands, performs grammar checks, classifies commands, etc.;
Reference numeral 2 denotes a control unit for generating and managing a correspondence table between an identification number (ID) given to a graphic and the command when the command is displayed on the graphic display device.
Reference numeral 33 is a command inverse generation unit that generates a command in response to an operation inputted from the graphic display device by an input device, and 4 is a control unit that performs input/output in response to input operations and input commands to the graphic display device. be.

FIG. 2 is a concrete example of the instruction ID correspondence table in the instruction ID correspondence table control section.

A case where a graphic is additionally generated from the graphic display device 5 by an input device will be described. In this case, the device control unit 4 generates a new identification number ID for the figure, and sends a series of operations necessary to generate the figure to the command inverse generation unit 33. The instruction inverse generation unit 33 performs processing to create this series of operations as an instruction, and combines this newly created instruction with the
ID is passed to the instruction ID correspondence table control unit 32, where an additional instruction ID correspondence table is created.

The position of the added table starts from the value of the maximum instruction number in FIG. 2 +1. Here, the command
The maximum ID value is from instruction input file 1 to input control section 2, instruction analysis section 31, and instruction ID correspondence table control section 3.
2. This has already been set when a graphic is displayed through the processing units of the device control unit 4 and graphic display device 5. When the instruction ID correspondence table in FIG. 2 is updated by the above addition, the input control section 2 updates the contents of the instruction input file 1.

By doing this, conventionally, the command input file 1 is connected to the graphic display device 5 via the input control section 2.
In the present invention, the contents of the command input file 1 can be added and updated via the command control section 3 in response to a graphic addition operation from the graphic display device 5.

Next, a case will be described in which a figure is deleted from the figure display device 5 using an input device. In this case, the device control unit 4 extracts the ID of the figure to be deleted from the operation of the input device, passes through the command inverse generation unit 33, and issues the command.
The ID is passed to the ID correspondence table control unit 32, and there,
Find the instruction number of the instruction ID and multiply its value by -1. Also, the number of deletion instructions is added by one.

After performing all of this processing for the deleted shape,
The contents of the command input file are updated via the input control section 2. At this time, the contents of the instruction input file 1 can be updated by searching the instruction ID correspondence table for instruction numbers with negative values for the number of instructions to be deleted and deleting those instruction numbers from the instruction input file 1. .

Here, the instruction inverse generation section 33 that generates instructions based on the input operation from the graphic display device 5 decomposes the instruction inputted from the input control section 2 into each instruction identification section and a data section. The processing that is the reverse of the processing that sends display data to No. 4 is performed. That is,
The input control unit 2 generates a series of operation commands for operations such as figure addition and deletion extracted by the device control unit 4, performs processes such as assigning command numbers to these generated commands, and so on. The processing results are now sent to.

Effects of the Invention As explained above, according to the present invention, the contents of the command input file are updated not only when registering commands in the command input file, but also when adding, deleting, and modifying figures on the graphic display device. By doing this, it is possible not only to establish a correspondence between displayed figures and commands, but also to efficiently display figures by redisplaying updated display figures from the command input file and by storing and managing instructions when generating display figures. There is a potential effect.
