DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic data creating apparatus for creating a graphic source program that can be read as a subroutine from graphic data of a graphic created using a mouse.

[0002]

2. Description of the Related Art FIG. 6 is a block diagram showing a configuration of a conventional graphic data creating apparatus. In FIG. 1, reference numeral 1 denotes a computer constituting each control means, to which a display unit 2, a keyboard 4, a hard disk 5, a floppy disk 6, and the like are connected.

Reference numeral 7 denotes a display control unit for controlling the display of the display unit 2. Reference numeral 8 denotes a key control unit for processing a signal from the keyboard 4 and outputting the processed signal to the graphic creation control unit 10 and the file control unit 14. 10 causes a graphic to be created on the screen of the display unit 2 in accordance with a signal from the keyboard 4, and the file control unit 14 stores the graphic data of the graphic on the hard disk 5 or the floppy disk 6.

In the apparatus configured as described above, when a figure is added as a part of the main software (program), the figure is "1" for each dot obtained by subdividing the display screen as shown in FIG. It is determined by the value of “0”. For example, the value of point A (coordinates 3 and 4) on the screen is “1”, and this set of “1” is a circle drawn. In addition, the value of a point that is not plotted, for example, point B (coordinates 5 and 4) is “0”.

FIGS. 8 and 9 show the flow of the conventional graphic data creation operation in which a graphic is handled as a set of dots obtained by dividing the screen as described above. The example of FIG. 8 shows a graphic drawing function library (subroutine) (a) representing coordinate data of a figure such as a point or a square.
This is a user-created program (b)
Then, the program is incorporated as a subroutine and sent to the compile link (c) to create an execution file (d). Then, the program is executed to display a graphic on the CRT (e).

In the example of FIG. 9, a picture (figure) drawn on a CRT is filed as a bit pattern, and a picture is created on a CRT (a) using dedicated software (program), and the picture is created in a file. (B) is stored in a bit pattern. Then, the picture is read out by the user program (c) and displayed on the CRT (d).

[0007]

However, in the above-described conventional graphic data creating apparatus,
Since a figure is handled as a set of dots obtained by subdividing the screen, there is a problem that the amount of data relating to the figure is large and the figure cannot be changed or adjusted. In the example of FIG. In the example of FIG. 9, filing can be performed after confirming the actual figure, but the data on the V (video) RAM is basically used. However, there is a problem that a large-capacity recording medium is required.

The present invention has been made in view of the above-mentioned problems, and does not require fine coordinate setting, has a small amount of data, does not require a large-capacity recording medium, and changes and adjusts figures. It is an object of the present invention to provide a graphic data creation device that is easy to use.

[0009]

According to the present invention, there is provided a graphic data generating apparatus for generating a graphic on a display screen in accordance with a signal from an input means such as a mouse, and a graphic generating control means for generating a graphic on the display screen. And a source creation control unit for creating a source program based on the read graphics data.The source program of the created graphics is used as a subroutine as a main program. It is configured so that it can be incorporated.

Further, when different graphic data at the same position on the display screen are read in an overlapped manner, an optimization control means for optimizing the graphic data to desired data is provided.

[0011]

In the graphic data generating apparatus according to the present invention, a graphic drawn by a mouse or the like is analyzed by the analysis control means, and a source program is generated based on the graphic data read here. Then, this source program is incorporated into the main program as a subroutine.

When a figure is overlaid and drawn at the same position on the display screen by the optimization control means, for example, the previous graphic data is erased.

[0013]

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, reference numeral 1 denotes a computer constituting each control means, which is connected to a display unit 2 using a CRT, a mouse 3 used as a graphic input means, a keyboard 4, a hard disk 5 used as a file, a floppy disk 6, and the like.

Reference numeral 7 denotes a display control unit for controlling the display of the display unit 2, 8 a mouse control unit for controlling an input from the mouse 3, 9 a key control unit for controlling an input from the keyboard 4, and 10 a mouse control unit. A graphic creation control unit (control means) for creating a graphic on the screen of the display unit 2 in accordance with the signal of (1), an analysis control unit (11) for analyzing the graphic created on the display screen and reading graphic data such as coordinate data ( Control means) and 12 are optimization control units (control means) for optimizing the graphic data to desired data when different graphic data at the same position on the display screen are read by the analysis control unit 11 in a superposed manner. Erase previous data with priority given to data entered later.

Reference numeral 13 denotes a source creation control unit (control means) for creating a source program representing the figure based on the graphic data read by the analysis control unit 11 or the graphic data optimized by the optimization control unit 12.
The figure source program created here is in a form that can be compiled by a C language compiler, and can be incorporated in the main program as a subroutine. Reference numeral 14 denotes a file control unit that stores the source program in the hard disk 5 or the floppy disk 6.

The above-described graphic data generating apparatus is configured as a tool for generating a C language source program for displaying a graphic when the graphic is generated on the CRT using the mouse 3. The flowchart of FIG. 2 shows the flow of the operation.

First, in the figure creation routine (S1), when a desired figure (picture) is created on the CRT using the mouse 3, the data of the figure is input to the analysis control unit 11 through the figure creation control unit 10. . Then, the analysis routine (S
In step 2), graphic data such as coordinate data of a figure drawn on a CRT is read. Next, an optimization routine (S3) is entered, and measures are taken for overlapping parts of the figures. For example, when a different figure is input in the same place, the previous figure is erased.

Next, a source program is created by a source creation routine (S4) based on the read graphic data, and stored in a file (S5). Then, a source text file is created from this program (S6), and this is used as a subroutine.

FIG. 3 shows a flow of operation when actually using the graphic source program created as described above. The main program and the graphic subprogram (a) are linked by the compile link (b) and stored in the execution file (c). Then, when the sub program is called by the main program, the graphic created by the mouse 3 is displayed on the CRT (d).

As described above, when a figure is created with the mouse 3, a sub-program for displaying the figure is created, so that fine coordinate setting required at the time of coding is unnecessary, the data amount is small, and the conventional method is used. Thus, it is not necessary to store the data obtained by dividing the screen, and a large-capacity recording medium such as a bit pattern is not required.

Further, the change and adjustment of the figure can be performed easily by the created source program, so that it is easy to make it correspond to various C languages by performing parameter judgment in the source creation routine.

FIG. 4 is a diagram showing a specific example of the operation of the above-described analysis routine, optimization routine, and source creation routine. In the analysis routine, graphic data of a figure drawn on the CRT is written. At this time, for example, if a circle, triangle, or square figure is created with the mouse 3, the coordinates X, Y of the center with respect to the circle are displayed. And a radius R ir (X,
The data (a) of (Y, R) is read as an input, and the data (b) of tri (...) Of the position coordinates of three points for a triangle, and the squ (4) of the position coordinates of four points for a square. …
..) Are read.

Next, when the optimization routine is entered, measures are taken for the overlapping portions of the graphics as described above. For example, in the above description, a circle, a triangle, and a square figure are input. delete.

Next, when the source creation routine is entered, in the above example, data of a circle and a square figure are finally left.
This is converted into a program as shown in FIG. By using this program as subroutine software as part of the main software, graphics can be easily displayed on the CRT.

[0025]

As described above, according to the present invention, a graphic created by a mouse or the like is analyzed to read graphic data, a source program is created based on the graphic data, and this is used as a subroutine as a main program. Since there is no need for detailed coordinate setting when inputting a figure, the amount of data is small, a large-capacity recording medium is not required, and the figure can be easily changed and adjusted.
