Abstract

PURPOSE:To simplify a command input operation by separating commands into plural parts by their functions, and storing data on commands of the previous time, and by adding the storage data relative to the abbreviated type commands. CONSTITUTION:A CPU1 edits graphics in accordance with input data and is further provided with a command table 11, abbreviated value setting table 12, abbreviated value table 13, and a command buffer 14. The CPU stores all of each command previously performed in the table 13, discriminates which part of the command is inputted at the time of inputting the command, and recognizes the abbreviated part during the command when the command is continuously inputted. It prepares a command by compensating for the part an abbreviated value stored in the table 13, which reduces the number of the process stages for inputting command.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field This invention relates to a graphic editing method using a computer or the like.

Conventional technology When a human and a computer perform a task while interacting with each other, it is important to be able to input the work details (hereinafter referred to as commands) to be performed by the computer in a simple manner and with fewer operating steps, which increases work efficiency. is important.

When using a calculator to edit a shape such as adding/selecting or moving a shape such as a line segment or rectangle that has already been entered into the calculator, conventionally the commands given to the calculator were, for example, move. , selection, etc., and a coordinate input section indicating the coordinate position of a destination, etc., and these commands Y were simply input one after another.

Therefore, input for editing could not be simplified.

Purpose of the Invention The present invention is based on the fact that when editing figures using a computer, etc., a part of the command to be executed from now on is often the same as a part of the previously executed command. When adding continuously and repeatedly, use the control part and line segment.

Focusing on the fact that the command contents of the controlled part such as a rectangle are the same, and when moving several figures by the same distance, the command contents of the control part and the coordinate input part are the same. , and its purpose is to provide a command input method that simplifies command input when editing figures.

Summary of the Invention Therefore, by storing all parts of previously executed commands in a default value table and identifying which part of the command was input when a command is input, it is possible to , the number of operational steps for inputting commands is reduced by recognizing omitted portions in commands and creating commands by filling in those portions with default values stored in a default value table.

Also, depending on the type of command, it may be difficult to use it as a default value for the next command, so when updating the default value table after command execution for each part of all commands, check which part of the command was executed. In addition to specifying whether to store the default value, the default value is effectively used.

Example An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a graphic editing device to which the present invention is applied, in which 1 is a central processing unit for graphic editing, and 2 is a keyboard, in which input keys are arranged according to the functions of commands to be input. . The input keys include commands, and for the control section, the \DD key instructs to add a figure, the DELE key to instruct deletion, the MOVE key to instruct movement, the MDFY key to instruct the transformation of a figure, and the figure. S L CT key to select a part, U to indicate not to select
NSE key, FIT key to align the figure to the height of the screen, FWIN key to align the figure to the specified range of size, CWIN key to align the image to the center of the screen, Execute XEQ
It has keys etc.

Furthermore, even if the object to be edited is a line segment or a rectangle, there are keys for line segments, keys for rectangles, etc. for the controlled portions of commands such as 3-, etc. Furthermore, it has a coordinate input key for inputting an editing position.

3 is a CRT for displaying input data, edited figures, etc.;

The central processing unit 1 edits and displays figures according to input data using a command table 11, a default value setting table 12, and a default value table whose details are shown in FIGS. 2 to 5. 13. A command buffer 714 is provided which temporarily stores a part of the command input using the keyboard and data read from the default value table 13 to create a completed command.

Note that the command buffer 714 is the control part of the command,
The controlled part and the coordinate input part are stored respectively.

In command table 11, <controlled part> coordinates human power part>
This indicates that the combination of ``Key 1 is my control section'' and those ``Key 1'' parts constitutes one command. For example, in the case of A D D4-, the control section () \DD)>, <Controlled part (LI)
NE)>, <coordinate input part> are input into one completed command, and two parts, control part (FWiN)><coordinate input part>, are input into 1 complete command. This means that there will be one complete command.

The above table is used to determine whether all input for one command has been completed, and to determine which part of the command should be extracted from the default value table.

Furthermore, if "store" is specified in the default value setting table 12, it means that that part of the command will be stored in the default value table 13 after the command is input.

Below, these command table 11, default value setting table 12, default value table 13, and command buffer 14
A method for simplifying command input according to the present invention using the following will be described.

In the configuration described in ``2,'' ■ When a part of the command is entered from the keyboard 2,
The central processing unit 1 identifies whether the input is a control unit, a controlled unit, or a coordinate input unit, depending on which key the input is made from.

(Tei) If the input is <control unit>, if the command buffer 14 is not empty, and if the command for the control unit or controlled unit is omitted, the command table will be displayed. 11 to find out which parts need to be input, and extract the uninputted parts from the default value table 13 (see Figure 6 (a)).
, completing the previous command. Furthermore, the default value table 13 is updated with the data of the default value setting table 12, and the control unit that is currently being input is transferred to the command buffer 14.
Store it in , and proceed to ① described below. (FIG. 6(A)) If the command buffer 14 is empty, the <control section> is stored in the command buffer and the process proceeds to (2) described later. (Fig. 6 (b)) 6. If the command buffer 14 is completely empty, the inputted <controlled part> is stored in the command buffer 1, and then the <control part> is manually operated. is moved from the default value table 13 to the command buffer 14, and the process proceeds to (2). (Fig. 7 (a)) If the control section in the command buffer 14 is not empty and the controlled section is empty, store the controlled section to be input in the command buffer 714 and proceed to [F]. . (Fig. 7 (b)) If both <control part> and controlled part> in the command buffer 714 are not empty, take out the <coordinate input part> from the default value table 13, complete the previous command, and omit it. Update the value table 13. Then, the controlled unit to be input this time and the control unit to be extracted from the default value table are stored in the command buffer 14, and the process proceeds to (2). (Fig. 7 (c)) ■ If the input is in the <coordinate input section> If there is an empty part in the command buffer 14, extract the necessary part from the default value table 13 and enter the coordinates you want to input. Add an input section to complete the command. After updating the default value table 13, return to step 7-(Fig. 8 (a)). If the command buffer is not empty, this <coordinate input section>
The command is completed. After updating the default value table, return to ■. (FIG. 8(b)) G) Check the command table 11 to see if the command input is complete. If completed, the default value table 13 is updated. Then return to ■.

In the above configuration, the operation will be described with reference to FIG. 9 assuming that the following inputs have been made.

Input (1) (2) (3) (4) (5) (6)
(7) Eight DD; LINE; PI, P2; PP, P
2'; Sl, CT; MOVE; Pl", P2";
Then, the central processing unit determines that the key operated in (1) is the ADD key, and the control command ADI) is written into the control section area 14a of the command buffer 14. I was then repeated in (2).

By pressing the IME key, LINE is written into the controlled area 14b of the command buffer. Similarly, coordinate human power P
1:P2 is written to the coordinate input canister 14c.

8- This completes one command.

Here, the default value setting table 12 is referred to, and if the control part of the command is ADD, it is determined that the control part, controlled part, and coordinate input part all need to be stored, and as shown in FIG. ADD, LINE Pl in default value table 13
:P2 is stored.

Next, in (3), P1' and P2' are input, and since this is an abbreviated format in which the control section and controlled section are omitted, ADD and LINE of the default value table 13 are respectively read into the command buffer 14, one command ADD,
LINE PI': P2' is completed.

Below, in the same operation as above, (5), (6), and (7) are 5
CLT, MOVE Pi", P2" are input, so for S C1,,,T, L obtained in the previous operation is used.
INE:Pi', P2'' is read from the default value table 13, and the command 5CLT:LINE:P1+,P2
” is 93hU.MOVE+, :1 vs. MOVE:
LINE: Pl', P2'' is completed, and a series of commands \DD; LINE; Pi, P2; r\, D □DOL
INE; r'l', P2';5LCT;LINE; Pi

is completed.

In the above process, input commands and created commands are displayed at predetermined positions on the CRT 3 screen.

With this command, the central processing unit 1 moves a predetermined line segment to the coordinates P on a certain drawing according to the above series of commands.
1, P2, P1', and P2' to edit the figure and display it on the CRT 3J2. These editing operations and display operations are similar to those known in the art, and their explanations will be omitted.

Effects of the Invention - As described in detail, this invention is a graphic editing device that divides commands into multiple parts according to their functions,
For each part, the data from the previous command is memorized as necessary, and for abbreviated commands, the command can be completed by adding this memorized data. If a part of a command is repeated, the command input operation can be simplified by omitting that part of the command input.
