Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a graphic processing device that allows figures to be drawn on a graphic display, stores the drawn figures, and outputs the saved figures when necessary.

It has been conventional practice to input graphic information from a character display or the like and display the graphic on a storage type graphic display based on the input graphic information. In order to save the figures drawn on the graphic display screen, such as blueprints, and retrieve them when necessary, it is necessary to store the figures on the graphic display in a magnetic disk device or the like. In the prior art, graphic information input from a character display is temporarily stored in a magnetic disk device or the like, and then the input graphic information is analyzed and the graphic is displayed on the graphic display. This type of graphic processing apparatus has the disadvantage that graphic output is delayed because the input graphic information is stored in a magnetic disk device or the like and then the graphic is displayed.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a graphic processing device that can perform graphic processing at high speed. Therefore, the graphic processing device of the present invention includes a graphic display, a graphic information input device, a main memory, an external storage device, and a processing device. is configured in the main memory, and the processing device has a function of analyzing graphic information input from the graphic information input means and displaying the graphic on the graphic display, and storing the input graphic information in the memory file. A function to store old graphic information in the memory file when it becomes full, a function to move part of the old graphic information of the contents to the external storage device, and a function to transfer the contents of the memory file to the external storage device when the graphic completion is notified. It is characterized by having a function of transferring data to a storage device. Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing an example of the equipment configuration of the present invention, and FIG. 2 is a functional block diagram of one embodiment of the present invention.

In the figure, 1 is a central processing unit, 2 is a graphic display, 3 is a character display, 4-1 and 4-2 are magnetic disk units, 5 is a memory 6 is a typewriter, and 7 is an XY plotter. ing.

In FIG. 1, a central processing unit 1 controls various calculations and the entire graphic processing device based on programs in a memory 5.

The graphic display 2 is of a storage type and displays graphics on the screen.
The graphic display 2 also has a tablet, from which graphic correction data can be input.

The character display 3 is used to input graphic information using an attached keyboard. For example, when inputting a circular arc, the center, radius, starting point, and ending point are input from the character display 3. The input graphic information is displayed on the screen of the character display 3. The magnetic disk devices 4-1 and 4-2 play the role of storing graphic information of completed drawings. The area of the memory 5 is divided into a program area for storing various programs and a memory file area for storing graphic information of figures currently displayed on the graphic display screen. The X-Y plotter 7 is a magnetic disk device 4
It outputs graphics based on the graphics information stored in 4-1 or 4-2, and functions as a hard copy.

FIG. 2 shows functional blocks of one embodiment of the present invention, in which 8 indicates a graphic analysis means and 9 indicates a memory file. When graphic information for specifying circles, arcs, straight lines, characters, etc., is input from the character display 3, the graphic analysis means 8 analyzes the graphic and stores the input graphic information in a memory file 9. The figure analysis means 8
In addition to graphic analysis, it performs processing such as memory file management, graphic output, system startup, system termination, graphic storage, and graphic enlargement. When graphic information is input one after another from the character display 3, figures based on this graphic information are sequentially displayed on the screen of the graphic display 2, and the input graphic information is sequentially stored in the memory file 9. Ru. If the memory file becomes full, old graphic information is transferred from the memory file 9 to the magnetic disk device 4-1 or 4-2. If you want to modify the shape displayed on Graphics Display 2, use Graphics Display 2.
A tablet attached to the display 2 is used to input correction position and correction figure information.

When the design drawing drawn on the screen of the graphic display 2 is completed, a termination command is input, and the set of input graphic information in the memory file 9 is transferred to the magnetic disk device 4-1 or 4-2.
and saved as a file.

As is clear from the above description, according to the present invention, a memory file for storing input graphic information is provided in the main memory, and graphic processing is performed using the memory file, so graphic processing can be performed at high speed. It becomes possible to do so.
