Abstract

PURPOSE:To reduce the whole display time. CONSTITUTION:At the time of inputting graph object display indication 101, a graph object display means 1 adds graph object registration indication 301 to a graph object storage means 5 and inputs present damage range 201, and displays graph object 301 on a display 6 except for the case when graph object 301 is completely included in the present damage range. At the time of inputting graph object erasing indication 201, a graph object erasing indication means 2 deletes graph object delete means 302 from the graph object storing means 5, erases graph object 302 from the display 6 and adds the erased range to a damage range storing means 4 as a damage range 202. At the time of inputting damage recovery indication 103, a damage recovery means 3 regenerates all the graph object 303 in a present damage range 203 to clear the damage range.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic drawing system, and more particularly to a graphic drawing processing system in an information processing system.

[0002]

2. Description of the Related Art A conventional graphic drawing system immediately performs a display process when a graph object display instruction is issued.

[0003]

In the above-mentioned conventional technique, the graph object for which the display instruction has been issued is completely included in the area that needs to be redrawn due to the previous deletion of the graph object. In this case, the same graph object is drawn twice when the display instruction is given and when the redrawing instruction is given.

[0004]

According to the graphic drawing system of the present invention, in the interactive graphic processing of the information processing system, when the graph object display instruction is inputted, the damage range is inputted from the damage range storing means,
When the graph object registration means is output to the graph object storage means and the graph object display means for displaying the graph object on the display and the graph object deletion instruction are input, the damage range is output to the damage range storage means and is sent to the graph object storage means. When a graph object erasing means for outputting a graph object erasing instruction and a graph object erasing means for erasing the graph object from the display and a damage recovery instruction are inputted, the damage range is inputted from the damage range storing means and all the graph objects storing means stored Enter the graph object group, and enter the damage recovery method to display all the graph objects included in the damage range on the display in the input graph object group and the graph object registration instruction. Then, the inputted graph object is stored inside, and when the graph object deletion instruction is inputted, the graph object storage means for deleting the inputted graph object from the inside, and when the damage range is inputted, the inputted damage range is stored inside. And a damage range storage means.

[0005]

The present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the present invention is
(A) When the graph object display instruction 101 is input, the first damage range 2 from the damage range storage means 4 is input.
When 01 is input, the graph object registration instruction 301 is output to the graph object storage means 5, and the graph object display means 1 for displaying the graph object 401 on the display 6 and (B) the graph object deletion instruction 102 are input, the damage range The second damage range 202 is output to the storage unit 4, the graph object deletion instruction 302 is output to the graph object storage unit 5,
When the graph object erasing means 2 for erasing the graph object 402 from the display 6 and the (C) damage recovery instruction 103 are inputted, the third damage range 203 is inputted from the damage range storing means 4 and stored from the graph object storing means 5. All the graph object groups 303 that are being processed are input, and among the input graph object groups 303, all the graph objects 403 included in the damage range 203 are displayed on the display 6, and (D) Graph object registration When the instruction 301 is input, the input graph object is stored internally, and when the graph object deletion instruction 302 is input, the graph object storage means 5 for deleting the input graph object from the inside and (E) damage range 202 are input. With that, the damage range 202 input
And a damage range storage means 4 for storing the inside.

Next, the operation of the graphic drawing system thus configured will be described.

One graphic unit (for example, a polyline) that constitutes a picture displayed by using a graphic on a display is called a graph object, and redrawing that occurs by deleting the graph object from the display is performed. The required area is called the damage range.

When the graph object display instruction 101 is input to the graph object display means 1, the graph object display means 1 inputs the damage range 201 which is the current damage range from the damage range storage means 4, and the graph object storage means 5 Except when the graph object registration instruction 301 for registering the information (for example, coordinate value, color, etc.) about the input graph object is output, and the input graph object is completely included in the input damage range. , The input graph object is displayed on the display 6 as the graph object 401.

When the graph object erasing instruction 102 is input to the graph object erasing means 2, the graph object erasing means 2 causes the graph object erasing means 5 to
A graph object deletion instruction 302 for instructing deletion of the input graph object information is output, and the input graph object is changed to the graph object 402.
Then, the damage range 202 indicating the range in which the graph object is deleted is output to the damage range storage means 4.

Damage recovery instruction 1 to the damage recovery means 3
When 03 is entered, the damage recovery means 3 sets the damage range 203 indicating the current damage range from the damage range storage means 4 and the graph object group 303 composed of all the graph objects currently registered from the graph object storage means 5. A graph object group that is partially or completely included in the input damage range of the input and input graph object group 303 is displayed on the display 6 as a graph object group 403.

Damage range 2 in the damage range storage means 4
When 02 is input, the damage range storage unit 4 adds the input damage range to the damage range stored inside.

When the graph object registration instruction 301 is input to the graph object storage means 5, the graph object storage means 5 stores therein the information on the input graph object, and the graph object deletion instruction 3
When 02 is input, the graph object storage means 5 deletes the information about the input graph object from the inside.

[0014]

According to the present invention, when a specific graph object is displayed, and the graph object is completely included in the current damage range, the graph object is displayed until a damage recovery instruction is given. By avoiding this, there is an effect that it is possible to improve the drawing speed by drawing only once.
