Abstract

PURPOSE:To make the display image of graphic data the same at the time of displaying graphic data in a display where a dot number is different. CONSTITUTION:The dot number of the display corresponding to a pre-existed system, which is stored in an environment setting part 42, and dot number data A of the display 31 corresponding to the new system are compared by a discriminating means 21 and an operating means 22 operates and displays graphic data in such a way that the display image of the pre-existed system and that of the new system becomes the same in the display image of graphic data.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for displaying graphics in information processing and the like.

0002

2. Description of the Related Art In systems that display graphics for information processing and the like, for example, when displaying graphics, graphic data is generated in accordance with the number of dots on the display to make the entire screen look well-balanced. For this reason, when displaying graphics with the same image on displays with different numbers of dots, the system must be changed to correspond to the number of dots of the displays.

0003

[Problem to be solved by the invention] However, as the number of dots on the display changes more frequently, it is inefficient to change the system every time, and it places an extremely heavy burden on the person in charge of the system. ing.

An object of the present invention is to solve the problems with such conventional graphic display systems, and to provide a graphic system that allows system personnel to develop and maintain the system without being concerned about the number of dots on the user's display. The purpose of this invention is to provide a display device.

[0005]

[Means for Solving the Problems] The graphic display device of the present invention includes a file section for storing data for displaying graphics, and a display section corresponding to the address of the data for displaying graphics in the file section. The environment setting section that stores the first dot number data compares and determines the second dot number data of the display to be used given in advance and the first dot number data of the environment setting section, and determines the comparison value. and a calculation section that changes the address of data for graphical display in the file section to data corresponding to the display to be used in accordance with the comparison value of the discrimination section.

[0006] In the present invention described above, it is desirable to add the second dot number data of the display to be used to the discriminator using a key.

Furthermore, in the present invention described above, it is desirable that the file section and the environment setting section be provided in the same memory.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The graphic display device of FIG.
, a control section 2 , an output means 3 , and a memory 4 .

Furthermore, the input means 1 is equipped with a key 11, and the control section 2 is equipped with a determination means 21 and a calculation means 22. The output means 3 includes a display 31, and the memory 4 includes a file section 41 and an environment setting section 42.

The input means 1 receives data indicating the number of dots on the display 31 when the key 11 is pressed. Then, data indicating the number of dots on the display 31 from the input means 1 is given to the determination means 21.

The determining means 21 determines whether the data indicating the number of dots on the display 31 from the input means 1 is larger or smaller than the number of dots on the display stored in the environment setting section 42 of the memory 4.

Based on the result of the determining means 21, the calculating section 22 calculates the display dots stored in the file section 41 of the memory section 4 so as to correspond to the size of the display 31. That is, by comparing the number of dots between the environment setting section 42 and the display 31, the dots to be displayed according to the size of the display 31 are calculated.

The file section 41 of the memory 4 stores data for graphic display. That is, the file section 41 in the memory 4 stores graphic data to be displayed and character data to be displayed, which have been input from another system.

The environment setting section 42 stores the number of display dots corresponding to the graphic data of the file section 41. For example, the data is stored as (vertical axis: 600 dots, horizontal axis: 800 dots).

Next, the operation of this embodiment will be explained using FIG. 2. Note that FIG. 2 is a flowchart illustrating the operation in one embodiment of the present invention.

First, in order to display a graphic, the operator operates the keys 11 of the input means 1 to input the number A of dots on the display 31 (the number of dots on the vertical axis, the number of dots on the horizontal axis, etc.). The control unit 2 uses this data (for example, 1200 dots on the vertical axis and 1600 dots on the horizontal axis) and the file unit 4.
The number of dots stored in the environment setting unit 42 (for example, 600 dots on the vertical axis and 800 dots on the horizontal axis) corresponding to the graphic data in the data C of No. 1 is extracted and compared (step 2). In this case, since the number of dots A on the display 31 is larger than the number of dots on the display corresponding to the graphic data in the file section 41,
The calculating means 22 calculates the display address of the graphic data in the data C of the file section 41 on the display 31 on both the vertical and horizontal axes based on the comparison value determined by the discrimination (step 2). This process is repeated until the end of the graphic data in the data C of the file section 41.

Based on this result and the character data, the control unit 2 sends the display data D to the display 31 to display the graphic data (step 2).
. If there is remaining graphic data, step ■
, ■repeat (step ■). Also, display all character data (step ■). In this embodiment, since the display position of the characters is the same as the number of characters displayed on the display, there is no need to change the display position of the characters.

Next, a specific example will be explained.

The calculation means 22 calculates the display address of the graphic data in the data C of the file section 41, for example.
When expressed as (vertical axis, horizontal axis), the address of each corner is (400
,100),(200,100),(200,400)
, (400, 400) with the data (600 dots, 800 dots) of the environment setting section 42 and the input data A.
(1200 dots, 1600 dots) are compared, and each is doubled and sent to the display 31. In this example, (800, 200), (400,
Graphic data displaying a rectangle whose corner addresses are 200), (400, 800), and (800, 800) is sent to the display 31 as data D.

In this embodiment, the number of dots on the display 31 is input by the operator by operating the keys 11, but the number of dots on the display 31 may be stored in the memory 4 in advance.

[0022]

[Effects of the Invention] As explained above, according to the present invention,
When displaying graphic data, the display image of the graphic data can be displayed in the same way even if the display has a different number of dots. Therefore, in systems that display graphic data, screens can be created by considering only the display image of the display currently in use, without being aware of the number of dots on the display. This eliminates the need to change the system, which has the effect of improving system productivity.
