Field of the Invention The present invention relates to a processing method of a graphic data processing apparatus for performing drawing with the aid of a computer, and more particularly, to a method of processing graphic data in a user-friendly operation procedure. It is configured as follows.

[0002]

2. Description of the Related Art In recent years, computer-assisted graphic data processing apparatuses have been actively used for architectural design and creation of various images and graphics. In this apparatus, by performing data processing on a graphic, it is possible to move, copy, or delete the graphic on the display screen, and to retrieve (generate) a stored graphic on the edit screen. This makes the work of creating figures more efficient.

As shown in FIG. 19, a graphic data processing device includes a position coordinate input means 7 such as a mouse for designating an input position on a display screen, and a graphic data processing means 9 for processing graphic data in a predetermined procedure. And a storage means 10 for storing graphic data and position information, and a graphic display means 8 for displaying a menu screen and a generated graphic.

In a conventional graphic data processing apparatus, as shown in FIG. 20, an initial area of a display screen includes an editing area 4 for editing a graphic and "generation" and "copy" representing menu items 6.
Mouse that moves in response to mouse movement
The cursor 5 and a trash can icon (pictogram) 31 for deleting the selected figure are displayed.

On this screen, a mouse operation is performed to move the mouse cursor 5 to the position of "generate", and a click (quickly pressing and releasing the mouse button) (FIG. 22)
(A)), the “generate” function is selected, the screen changes to a generation menu screen (FIG. 21), and icons are displayed in a list. When one of the icons is selected with the mouse (FIG. 22B), the icon list disappears, and only the selected icon is displayed in the editing area 4 (FIG. 22C).

There are two ways to delete a figure in the editing area 4. One is to select a figure to be deleted from the editing area using a mouse (see FIG. 24).
(A)), select the "Delete" menu (FIG. 24)
(B)). In another method, after selecting the figure to be deleted in the editing area, the trash can icon 31 is selected (FIG. 2).
2 (d)). In either case, the figure specified by the mouse cursor 5 can be deleted (FIG. 24).
(C)).

As shown in FIG. 26, the storage means 10 stores the following data required to execute such an operation.

Screen area data; data specifying the position (X, Y) of each area of the "generate", "duplicate", "delete", edit area and trash can icon displayed on the initial screen; (FIG. 27A) (this initial data remains unchanged even during execution of the graphic processing).

Generate menu icon data; icon numbers of icons displayed in a list on the generate menu screen, and icon image data (graphics are displayed in bits)
That specifies the relationship between the data and the shape data of the figure (FIG. 2)
7 (b)) (this initial data remains unchanged even during execution of the graphic processing).

Trash icon data; Trash icon
Data for specifying the icon number and icon image data of 31 (FIG. 27 (c)) (this initial data remains unchanged even during the execution of the graphic processing).

Edit area graphic data: Graphic data of a graphic displayed in the edit area 4; a selection flag indicating that the graphic is designated by a mouse; a position (X, Y), shape, size, direction, etc. of the graphic. (FIG. 27 (d)) (The number of records in this data table is 0 in the initial state. When "generation" and "copy" are performed during execution of graphic processing, one record is added and "deletion" is performed. In the case of "move", the position data of the record is changed.)

The storage means 10 further includes a processing end flag indicating whether the processing selected by the mouse has been completed,
Position information indicating a position (X, Y) on the screen specified by the mouse, a selected area name for inputting an area name of an area specified by this position information, and a selected icon number for inputting an icon number of a figure in the area And the like are provided.

The graphic data processing means 9 executes various graphic processings selected by the mouse while operating data stored in the storage means 10.

In the conventional graphic data processing apparatus, as shown in FIG. 28, initial setting of the storage means 10 (steps 1 to 3).
Is performed, the selected graphic processing is executed (steps 4 to 29).

As shown in FIG. 29, the initial setting of the storage means 10 is as follows: Step 1: Turn off the processing end flag of the storage means; Step 2: Clear the storage areas of the position information, the selected area name and the selected icon number. Step 3; image area data, generated menu data,
Reads trash can icon data and edit area figure data from a file.

Further, in order to perform graphic processing (FIG. 3)
0) First, an area is selected by a mouse, and data relating to the selected area is read into the storage means 10 in the following procedure (FIG. 31).

Step 4: storing the position information input from the mouse in the position information column of the storage means 10; Step 5: referring to the screen area data, searching for an area name corresponding to this position information; Step 6 The corresponding area name is stored as the selected area name.

Next, according to each of the stored selection area names (step 7), the generation menu processing (steps 8 to 1)
2), a copy menu process (steps 13 to 15), a delete menu process (steps 16 to 18) or an in-edit area process (steps 19 to 28) are executed. When these processes are completed, the process end flag is set. It is determined whether it is on (step 29), and if it is off, the process is repeated from step 4.

The generation menu process is performed in the following procedure (FIG. 32).

Step 8: All the selection flags of the editing area graphic data table read into the storage means 10 are deleted. Step 9: The image data of all generated icons is displayed by referring to the generated menu, icon and data table. A list is displayed on the screen (FIG. 21).

Step 10: When one of the generated icons is selected by the mouse (FIG. 22 (b)), the icon number of the selected icon is stored in the selected icon number column. Step 11: The generated icon on the display screen is displayed. The list display is erased, and step 12; one record of the editing area graphic data record is added, and the shape data relating to the icon of the previously stored number is copied from the generated menu, icon and data table, and the record is added to this record. Add a selection flag. The position (X, Y) data at this time is set to a predetermined value (for example, (5, 5)).

Thus, the figure selected from the list of figures is displayed in the editing area 4 of the display screen (FIG. 22 (c)).

In the copy menu process, as shown in FIG. 23, as an operation on the display screen, a figure to be copied in the editing area 4 is designated by the mouse cursor 5 (a), and then the "copy" menu is selected. (B). Then, a copy of the designated figure is displayed at a position on the editing area 4 which is shifted from the original figure by a certain distance (c).

Along with this operation, the operation of the copy menu process proceeds in the following procedure (FIG. 33).

Step 13: A record with a selection flag is searched from the edit area graphic data. Step 14; if it exists, step 15; one edit area graphic data record is added. The data of the detected record is copied there. Next, clear the selection flag of the record of the duplication source,
The position data of the duplicated record is changed to a position shifted by a certain amount.

In the deletion process, a menu is selected.Method

The editing area graphic data is graphic data representing the position (X, Y), shape, size, orientation, etc. of the graphic displayed in the editing area 4 (FIG. 4 (a)). The number of records in this data table is 0 in the initial state, that is, in a state where no figure is displayed in the editing area, and when “generate” and “copy” are performed during the figure processing, a record is added. When "deleted", the number of records decreases. "Move"
In the case of "save", the data of the record is updated.

The icon data stores icon data used for generation, storage, and deletion. Each icon number and icon image data (01100011 @) are stored.
Etc.) and shape data of a figure to be displayed when this icon is selected (FIG. 4B).

The icon data for generation includes a large number of basic graphic data. These data are written as initial data, and are not changed during execution of the graphic processing (that is, writing to the generated icon data is not allowed). The icon data for deletion is image data of a trash can, and the shape data is empty. This icon data is not changed during the process. On the other hand, in the initial state, the image data is blank and the shape data is empty, but can be written during the execution of the graphic processing, and the data is updated every time “save” is performed. It is.

The screen area data includes the generation, storage, deletion, and editing areas displayed on the initial screen, and coordinates and icon IDs corresponding to each of the generated graphic icon, the stored graphic icon, and the deleted area icon. The data to be specified. These data are unchanged even during the execution of the graphic processing.

The editing area graphic data and the icon data for storage stored in the storage means 10 are updated by an editing command. (A)-illustrated in FIG.
Data update is performed as follows in response to each editing instruction of (e).

Corresponding to (a); the shape data of the icon number 11 of the icon data is added to the editing area graphic data as a new record. The position data of the added record is rewritten to (5, 5).

Corresponding to (b): The shape data of the icon number 21 of the icon data is added to the editing area graphic data as a new record. The position data of the added record is rewritten to (5, 5).

Corresponding to (c); delete the data record having the position coordinates of (5, 5) of the edit area graphic data.

Corresponding to (d); the position coordinates of the figure data record having the position coordinates of (5, 5) in the edit area figure data are rewritten to (10, 10).

In correspondence with (e); a graphic data record having the position coordinates of (5, 5) in the edit area graphic data is added as the shape data of the icon number 21 of the icon data. The image (image) data displayed at the position (5, 5) in the editing area is displayed as an icon
The data is rewritten to the image data part of the icon number 21 (icon for storage) of the data.

Now, in this graphic data processing apparatus,
The operation procedure of the graphic data processing means for processing graphic data will be described with reference to a flow chart.

In the graphic data processing means employing this processing method , as shown in FIG. 10, the storage means and the display means are initialized (steps 1 to 3), and area information is created based on the input information of the mouse cursor. (Steps 4-1
