Description

[Detailed Description of the Invention] [Summary] Regarding the graphic display process in a graphic processing system that manages graphic information by segmenting, commands for segment display and normal display are enabled even for graphic output devices that do not support the segment function. The purpose of this method is to divide the information that defines a figure into segments and manage them, and to create a non-geometric attribute for outputting the figure to a figure output device according to the display attributes specified for each segment. , instructs the graphic output device based on a status table in a predetermined format, and in response to a predetermined display command and a normal command that specify the segment, display the figure belonging to the segment, and change the display state from the display state to the normal display state. In a graphic processing system that processes a return to , if the graphic output device is a device that does not support the segment function, the graphic output device that is the same as the status table is generate a plate-like layer table in the format, and in the case of the display command, modify the required portion of the plate-like layer table according to the display color index of the graphic information, and use the plate-like layer table in the state table. Then, the graphics output device is configured to notify the non-geometric attribute and re-output the graphics of the segment.

[Industrial application field]

The present invention relates to a segment display processing method for validating segment display and normal display commands even for a graphic output device that does not support the segment function in a graphic processing system that manages graphic information by segmenting.

[Problems to be solved by the prior art and the invention] For example, the so-called I5O, which is an international standard of the International Organization for Standardization,
- In the GKS standard, information about figures is divided into segments corresponding to each appropriate figure, and so-called geometric attributes such as figure, size, display position, line type, line width, green color, marker type, size, etc. Each piece of information defining color and other so-called non-geometric attributes is managed as an intra-segment element, and by specifying a segment using a segment identification name, the corresponding figure can be manipulated.

FIG. 3 is a diagram explaining the processing of the graphic processing system.

In FIG. 3(a), an example of the definition of a graphic specified by the segment identification name "segment A" is from "segment A start" to "segment A end" in the application program 1 that uses graphic processing. Polyline color index (1) J specifies the display color of the polyline figure specified by the next "Fold &1...J" and "Polyline 09...

,'' defines a polyline figure by specifying the number of vertices and coordinates using parameters not shown.

"Marker color index (3)" specifies the color of markers such as stars, asterisks, black dots, etc. specified in the next "marker row". Further, the "display color index (3)" is a definition of a display color when a figure is displayed, and "display" refers to displaying the figure in an emphasized state.

The graphic output unit 2 has a status table 3, updates a predetermined item in the table 3, and then updates [fold &1. ．． ．． ．． Before instructing the graphic output device 5 to output a polygonal line according to j, the state table 3
The graphic output device 5 is notified of the non-geometric attributes set in .

In this case, the same content as the previously notified attribute is held in the graphic output device 5, so in order to omit notification, the device state is such that the content stored in the graphic output device 5 is stored. Compared with Table 4, only the different items are notified, and the device status table 4 is updated according to the contents of the notified items.

When the graphic output device 5 is a device that supports the segment function, the graphic output device 5 receives the attribute information received from the “start of segment” to “end of segment” shown in the graphic output device 5 of FIG. 3(a) into the segment. The contents can be changed by a command specifying a segment identification name.

Therefore, for example, "segment) A" shown in application program 1
When the graphic output unit 2 receives the command “reveal”, the third
As shown in Figure (bl), if this is notified to the graphic output device 5, the graphic output unit W5 can perform the revealing process based on the information of the segment A held and output the revealed figure of the segment A.

Even when changing from a revealed state to a non-displayed state (hereinafter referred to as a normal state), the same process can be performed using a command such as "segment A normal", for example.

However, there are still many graphic output devices that do not support the segment function, and in that case, it is not possible to write a command such as "reveal segment A" in an application program. There is a problem in that programs such as ``Programme'' cannot be executed, and individual operations such as changing the color index must be specified in the application program if an output state similar to that of display and normal display is to be achieved. .

An object of the present invention is to provide a segment display processing method for validating segment display and normal display commands even for graphic output devices that do not support the segment function.

[Means to solve the problem]

FIG. 1 is a process flowchart showing the configuration of the present invention.

The figure shows the processing flow of the graphic output unit in response to commands for revealing and normal displaying of segments, and 10 to 15 are processing steps.

[For production]

The graphics processing system uses the graphics output unit to manage information that defines graphics by dividing it into segments, and outputs non-geometric attributes to the graphics output device in accordance with the display attributes specified for each segment in a predetermined format. Instructs the figure output device based on the status table, and in response to a predetermined display command and normal command that specify a segment, processes the display of figures belonging to the segment and the return from the display state to the normal display state. do.

When the graphic output unit receives a display command and a normal command, it identifies whether the graphic output device supports the segment function in processing step 10 of FIG. 1, and if it does not support the segment function, it processes the In step 11, a plate-like layer table in the same format as the status table is generated based on the graphic information of the segments designated as the display command and the normal command.

According to processing step 12.13, in the case of a reveal command:
Required portions of the plate-like layer table are corrected according to the revealing color index of the graphic information.

Next, in processing step 14, the plate-like layer table is switched to replace the state table, the figure output device is notified of the non-geometric attribute, and the figure is re-outputted according to the figure information of the segment, so that the specified segment is Re-output the figure in the visible color or normal color. Note that if it is determined in processing step 10 that the graphic output device supports the segment function, a command is notified in processing step 15 as usual.

With the above processing method, it is possible to easily apply display and normal commands to graphic output devices that do not support the segment function by using the notification function of non-geometric attributes based on the status table. Ru.

〔Example〕

FIG. 2 is a diagram illustrating an example of the process shown in FIG. 1. As shown in FIG.
In addition to the device status table 4, for example, a device capability table 21 is provided, and information indicating whether the graphic output device 22 supports the segment function or not is held corresponding to each graphic output device. .

The graphic output unit 20 outputs “segment A” from the application program 1.
When the command is received for "display" or "segment A normal",
In processing step 10 of FIG. 1, according to the device capacity table 21,
It is determined whether the graphic output device 22 supports the segment function, and if the graphic output device 22 supports the segment function, in step 15, "segment A reveal" is notified as in the conventional method, and the process ends.

If the segment function is not supported, a plate-like layer table 2 in the same format as the status table 3 is created based on the graphical information of the segment specified as the reveal command or normal command in processing step 11.
Generate 3.

In addition, if the current command is a display command as identified in processing step 12, the required portion of the plate-like layer table 23 is modified in accordance with the display color index of the graphic information (in the figure, the "broken line color index" index is The number has been modified from ``1'' to ``3'', which is defined as the revealing color).

Next, in processing step 14, the plate-like layer table 23 is switched to be used instead of the state table 3, and as shown in FIG. , notifies the graphic output device 22 of the non-geometric attributes of the different parts, and re-outputs the graphic according to the graphic information of the segment, thereby outputting the graphic of the specified segment in the revealing color. to erase.

When processing a normal command to return to normal display, as shown in FIG. 2(b), the temporary status table 23 generated in processing step 11 is used as is (without being modified with the revealing color index). Since the graphic output device 22 is used to perform the process in step 14, the graphic output device 22 is rewritten to a graphic output that is not in the revealed state.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in a graphic processing system that manages graphic information by segmenting, graphic output devices that do not support the segment function can display segments in the same way as devices that support the function. and normal display commands can be easily made effective, which has a significant industrial effect of reducing the burden on application programs and improving system usability.
