[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to graphic processing @ placement, and in particular, to moving a graphic displayed on a display screen to a desired position through conversation with a user. The present invention relates to a graphic processing device having a moving configuration.

[Prior Art] A conventional device of this kind, for example, Apple Computer
Personal computer manufactured by Ter Corporation Personal computer 9 type ACINT08A "MACDR, AWII (
There is a device such as that described in "CLAR18".

FIG. 3 is a block diagram showing the configuration of a conventional graphic processing device typified by the device described above, in which numeral 1 denotes a storage section for storing graphic information, and numeral 2 stores raster information (dot information) from the graphic information in the storage section 1. 3 is a frame memory section that stores the dot information converted in the vector/raster converter 2 for display, and 4 is a frame memory section 1 to 4 in the frame memory section 3. A video signal generator for periodically reading out information and converting it into visual information; 5 is a display unit using a raster scan method such as a CRT; 6 is a unit for specifying a figure displayed on the display unit 5 by the user; 7 is a user command analysis unit that analyzes commands from the user to perform graphic processing; 8;
1 is a graphic information processing unit that processes graphic information based on commands from the user and input position information, and stores the processed graphic information in the storage unit 1.

In the conventional graphic processing apparatus configured as described above, the storage area of the frame memory section 3 is usually associated with the number of effective display pixels of the display section 5.

Furthermore, the display operation of marking on the display section 5 is performed independently of the conversion processing of the vector/raster conversion section 2, and the dot information stored in the frame memory section 3 is applied to the display control signal from the video signal generation section 4. Therefore, it is read out sequentially at a rate of, for example, 30 to 40 times/second, and is sequentially read out as visual information.
It is sent to the display section 5. On the other hand, the vector/raster conversion section 2 reads the graphic information in the storage section 1 and performs a process of sequentially converting pixels in the frame memory section 3 corresponding to the graphic information into bright spots.

The user command analysis section 7 analyzes commands from the user for performing graphic processing such as graphic drawing, graphic movement, and graphic deletion, and sends them to the graphic information processing section 8 .

The positional information input unit 6 is a part for inputting a figure to be subjected to graphical processing and positional information such as coordinate values required for the graphical processing. Once the positional information is input, the information is transferred to the graphical information processing unit. Send on 8th. The graphic information processing unit 8 integrates the command from the user command analysis unit 7 and the position information from the positional information input horn unit 6, and stores it in the storage unit 1 as new graphic information. Processes such as updating the graphic information in the file are performed.

Here, the case of editing a figure, especially the case of moving a figure, will be explained.

FIG. 4 is an exemplary diagram of a display screen, in which a circular 9
and character string 10 are displayed. These graphical information are
Both are stored in the storage section 1, and the vector/raster conversion section 2 converts the graphic information into raster information and stores it in the frame memory section 3, which is then read out by the video signal generation section 4 and displayed on the display section. 5, and is provided to the user as a display screen as shown in the figure.

Here, in order to move the character string 10, the user selects a figure movement command from the figure processing command list 11, and then selects the character string 10 to be moved using an input device such as a mouse. Then, the user instructs the destination position using the input device. The location information of the destination is input by moving the position indication mark 12, such as an arrow, displayed by the input device to the corresponding position on the display screen, and performing a position determination operation such as pressing a button on a mouse. The selected graphic information and the position information input into the position information input unit 6 by the position determination operation are sent to the graphic information processing unit 8. Then, the graphic information processing unit 8 records the selected graphic information from the position information input unit 6.
The corresponding graphic information in the tM section 1 is searched, and since the command from the user command analysis section 7 is to move the graphic, the current graphic position information is deleted and changed to the position information from the position information input section 6. In this case, since the command is to move a figure, information other than the position of the figure information is not changed. Vector/raster converter 2
In accordance with the changed graphic information in the storage unit 1, the graphic information is converted into raster information and stored in the frame memory unit 3. The accumulated raster information is read out by the video signal generation section 4 and displayed on the display section 5. This results in
In the display screen shown in FIG. 4, the character string 10 before movement is
is deleted and displayed as the moved character string 13.

[Problem to be Solved by the Invention 1] In conventional graphic processing devices, when moving a figure, the position of the destination figure is designated by the absolute position from the position information human input unit 6 while looking at the display screen, so that one figure cannot be moved from another figure. There is a problem in that when performing processing such as displaying figures in the middle, for example, errors occur in the relative positional relationship between the figures.

This invention was made to solve the above-mentioned problems, and it is possible to specify the destination of a figure as a relative position with respect to other figures, thereby making it possible to accurately determine the relative position of other figures. The purpose is to obtain a graphic processing device that is

[Means for Solving the Problems] The graphic processing device of the present invention includes a graphic moving means (position information calculation unit 14 ).

[Operation] In this invention, when the movement destination of a figure is specified as a relative position of another figure, the figure moving means receives a movement command based on the relative position specification and the position information of the figure which is the source of the relative position information. The absolute position information of the destination is determined by calculation, and the figure to be moved is moved to the specified position.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In the figure, 1 is a storage unit that stores graphic information, 2 is a vector/raster conversion unit that converts the graphic information in the storage unit 1 into raster information (also called dot information), and 3 is a vector/raster conversion unit. A frame memory section 4 stores the dot information converted in the section 2 for display; 4 a video signal generating section for periodically reading out the dot information in the frame memory section 3 and converting it into visual information; 5; 6 is a raster scan type display unit such as a CRT, 6 is a position information input unit for the user to specify a figure on the display unit 5, and 7
8 is a user command analysis unit that analyzes instructions from the user to perform graphic processing; 8 is a user command analysis unit that processes graphic information from the commands from the user and the input position information, and stores it in the storage unit 1; The graphic information processing unit 14 is a position information calculation unit that calculates absolute position information of a movement destination from a movement command based on relative position specification and position information of a figure that is the source of the relative position information.

FIG. 2 is a diagram showing an example of the display screen of this embodiment, where 9 is a figure to be moved by specifying a relative position, 10 is a figure to be moved, and 12 is an arrow etc. displayed by an input device. 13 is a position indication mark, 13 is a figure after being moved, and 15 is a list of user selections - 4 figure processing commands, including figure movement by relative position specification.

Next, the operation will be explained.

First, graphic information such as 9 and 10 displayed in FIG. The data is stored, further read out by the video signal generating section 4 and displayed on the display section 5, and provided to the user as a display screen as shown in FIG.

Here, if the user wants to move the character string 10 by specifying a relative position, the user selects a figure movement command by specifying a relative position from the figure movement command list 15, such as "middle", Next, the character string 10 to be moved is selected using an input device such as a mouse, and the figure 9 to be moved by specifying the relative position is selected using the input vi position. The user command analysis unit 7 notifies the graphic information processing unit 8 that a graphic movement command based on relative position specification has been selected from the graphic processing command list 15. Further, the selected two pieces of graphic information are notified from the position information input unit 6 to the graphic information processing unit 8.

In the graphic information processing unit 8, since the instruction from the user command analysis unit 7 is to move a graphic by specifying a relative position, the graphic information processing unit 8 receives two pieces of selected graphic information from the position information input unit 6, and selects the corresponding figure information in the storage unit 1. Search for two pieces of graphic information. First, since it is a figure movement, the current figure position information of the figure information corresponding to 10 figures is deleted. Next, in order to obtain the absolute positional information of the movement destination, the positional information of the figure 9, which is the source of the relative position, and the figure movement command obtained from the user command analysis section 8 are used.
It is sent to the position information calculation unit 14. The position information calculation unit 14 performs arithmetic processing on the position information of the figure 9, which is the source of the relative position, in accordance with the type of figure movement command, in this case "middle", and uses the absolute position information after the movement to perform figure information processing. Reply to part 8. The graphic information processing unit 8 changes the position information of the corresponding graphic information in the storage unit 1 based on the returned absolute position information.

0 The vector/raster conversion unit 2 converts the graphic information into rask information according to the changed graphic information in the storage unit 1 and stores it in the frame memory unit. The video generating section 4 reads out the rask information in the frame memory section 3 and displays it on the display section 5.

Through such processing, in the display screen example shown in FIG. 2, the character string 10 before movement is erased and is displayed as the character string 13 after movement.

[Effects of the Invention] As described above, according to the present invention, when moving a figure,
Since the configuration specifies the position after movement 0 based on the relative position with other shapes, it is possible to accurately determine and display the relative positional relationship with other shapes, and it is possible to associate multiple shapes. This has the effect of being extremely useful for display purposes.
