Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a graphic editing control device, and particularly to display control of a graphic to be edited, which is suitable for improving the operability of graphic editing.

[Background of the invention]

When editing figures using conventional word processors, etc., the display method for the specified figure is as follows:
How to display target and non-target shapes in different colors, how to display target shapes by placing the cursor on them,
There were methods such as displaying an arrow or the like near the target figure, or changing the line type of the target figure.
However, the method of changing colors cannot be applied to display devices with monochrome screens. The cursor-positioning method does not allow you to manipulate multiple shapes at the same time. With the method of displaying arrows, identification is difficult on a screen where a mixture of figures is displayed. Furthermore, the method of changing the line type has the disadvantage that it is impossible to identify figures of the same line type when they are displayed on the display screen.

[Purpose of the invention]

An object of the present invention is to enable, in a figure editing function, to visually easily distinguish between figures designated as targets for editing operations and figures that are not targets from among a plurality of figures displayed on a display device. Moreover, the object of the present invention is to provide a graphic editing control device that can easily restore the original graphic shape when the target designation is canceled due to completion of editing, etc., and can improve the operability of the graphic editing function.

[Summary of the invention]

In a figure editing operation, the present invention includes a target specifying means for specifying a figure to be edited among a plurality of figures displayed on a display device; Inversion overwriting means for overwriting a figure with a line width wider than the line width of the target figure in black and white inversion, edit input end input means for inputting the end of editing input for the target figure for editing operation, and input from the edit input end input means. By providing means for inverting the black and white of the target figure that has been reversed and overwritten by the edit input end input, the target figure is displayed in reverse during the figure editing operation to make it easier to distinguish it from other figures, and when the editing operation is completed, the target figure is displayed in reverse. It is characterized by easily obtaining a normal figure after editing by re-inverting the image.

[Embodiments of the invention]

Hereinafter, an example in which the present invention is implemented for graphic editing control on a keyboard-type Japanese word processor will be explained with reference to the drawings. FIG. 1 is a block diagram schematically showing the hardware configuration of a keyboard-type Japanese word processor to which the present invention is applied. 1 is a figure,
A display device for displaying characters, symbols, and operating procedures; 2 is a display device for displaying information on figures, characters, and symbols;
A storage device for storing programs; 3 an input device for inputting figures, characters, symbols, and operating procedures; 4
5 is an output device for printing documents and graphics, and 5 is a control device for controlling each of the devices 1 to 4.

FIG. 2 shows the key arrangement on the keyboard surface of the input device 3. As shown in FIG. Numeral keys 3-1 are capable of directly inputting numerical values, cursor keys 3-2 are used to instruct cursor movement, and execution keys 3-3 are used to execute various processing functions of the word processor.

The following will explain the display contents on the display device 1 shown in FIGS. 3 to 7 and the graphic editing process flowcharts of the processing device 5 in this embodiment shown in FIGS. 8 to 9.

FIG. 3 is a diagram in which the processing device 5 stores the flowchart figure input from the input device 3 in the storage device 2, and then displays the flowchart figure on the display device 1. Reference numeral 1-1 denotes a frame indicating a graphic display area, which clearly indicates the range of the area set by the operator when performing a graphic editing process operation. The word processor has a figure editing function that allows figures to be input, moved, copied, etc. freely within this frame area 1-1. 1-2 is a matrix display showing functions that can be executed in the figure editing process, and when selecting and executing the functions displayed in this matrix 1-2, press "1" to "" on the numeric keypad 3-1. 9” key to select (Matrix 1
-2 corresponds to the key arrangement of "1" to "9" on the numeric keypad 3-1). In addition, when performing graphic input processing, pressing the "•" key on the numeric keypad 3-1 changes the word processor to graphic input processing control, and matrix 1-2 is used for graphic input. Changes to matrix display.

In the display state of FIG. 3, the processing device 5 is in the editing function input waiting state A of the processing flowchart of FIG. Here, the distance between shapes 1-3 and 1-4 and shapes 1-5, 1-6, 1-7, and 1-8 (character strings can also be treated as shapes) is far, so the operation to reduce the distance is necessary. The movement processing function to be executed will be explained. When the "8" key of the numeric keypad 3-1 corresponding to the movement processing function of the matrix display 1-2 is input, the processing device 5 performs the movement determination process B of FIG. 8 and enters the control mode in which the movement processing function is executed. Transition.

FIG. 4 is a display screen of the display device 1 during the movement process of the graphic editing process to which the present invention is applied in an embodiment. The processing device 5, which has entered the movement processing control mode, executes movement object designation input processing and movement object figure special display processing in process C of FIG.

FIG. 9 is a detailed diagram of this process C. First, the target designation input guidance display process C5 is executed, and the matrix display 1-2 shows "target designation" and "target cancellation".
and “All Cancel” is displayed as “1” on the numeric keypad 3-1.
~ This is done in association with the key arrangement of "9". Next, key lead C10 is executed. When there is a key input, it is determined in process C15 whether it is a cursor key or not,
If it is a cursor key, the process moves to process C20 and cursor movement process is executed. Here, the operator presses the cursor key 3-2 to enter an instruction to move the cursor 1-9 so that the cursor 1-9 is placed on an arbitrary line on the target figure. The amount of movement of the cursor 1-9 changes alternately in units of 1 dot and 7 dots each time the cursor movement amount change key 3-4 is pressed, so when specifying one of the adjacent figures as the target, It is preferable to press the cursor movement amount change key 3-4 and operate in units of one dot. In this movement amount changing process, it is determined in process C15 whether or not there is a cursor movement amount change key input, and if the key input is the key input, the process moves to process C30 and is executed. When the cursor 1-9 is placed on the target figure for target designation, the operator presses "7" on the numeric keypad 3-1 corresponding to "target designation" in the matrix display 1-2.
Press either the "8" or "9" key. Processing C
When the key input is detected in step 35, the processing device 5 moves to step 40, and based on the graphical information in the storage device 2, selects a target including the cursor 1-9, which is closest to the center of the cursor 1-9, and which is still the target. Search for unspecified shapes. At this time, if there are multiple untargeted figures at the same distance, the first input figure is searched. Next, overwrite the corresponding shape (target designation shape) with a line width of the shape + 2 dots so that the outline of the shape becomes a double line, inverted black and white, and identify it as a shape other than the target designation. Display as special as possible. FIG. 5 is an example of a special display when target-designated figures intersect with each other, and when target-designated figures and non-target-designated figures intersect. The operator repeats the above operation and sequentially creates shapes 1-4, 1-5, 1-6, 1-
7, and specify character strings 1-8 as targets. In this embodiment, the target designation display of the character string is such that the entire character string is displayed in black and white inverted.

Furthermore, in this embodiment, there are two methods for canceling a figure once designated as a target figure. One is the cancellation method for each figure, which is to press one of the "4", "5", and "6" keys on the numeric keypad 3-1 that corresponds to "Target Cancellation" in the matrix display 1-2. It is executed by This process is
The key input is detected in process C45, and process C50
This is executed by moving to , canceling the special display of the object figure closest to the cursor, including cursors 1-9. The other one is matrix display 1-2
"1" on numeric keypad 3-1 corresponding to "all release"
The special display of all target figures is canceled by pressing the key. This complete cancellation process is performed in process C55.
It is determined whether or not the all release key has been input, and if the key has been input, the process moves to process C60 and is executed. The process of returning the special display of the target figure to the original figure display is performed by overwriting the figure in black and white inversion with a line width equal to the line width of the figure + 2 dots, similar to the special display of the target figure. .

When the designation of the figure to be moved is completed, the operator presses the execution key 1-3. The processing device 5 is
When execution key input is detected in process C65, process C
The process moves to step 70, where a target designation end flag is set to end this target designation and special display processing.

Thereafter, the processing device 5 moves to process D in FIG. 8, determines whether the target designation is complete, and shifts to a destination designation control mode. FIG. 6 is an example of a display on the display device 1 when a moving operation is being executed. The processing device 5 executes the process E, that is, the process of displaying the reference point mark 1-10 at the reference point of the target figure. In this process, the shapes 1-5, 1-
6, 1-7 and the character string 1-8 from the graphic information in the storage device 2, and place a reference point mark 1-10 at the reference point in a reverse filled rectangle (19 dots x 19 dots). Display in .

The direction of movement is determined by pressing the cursor key 3-2.
It is possible to freely specify the destination in both the up, down, left and right directions. Also, the amount of movement is “F1” on input device 3.
By pressing the key 3-4, it is possible to alternately switch between 1 dot unit and 7 dot unit.

The processing device 5 reads the key input in processing F, and each time the cursor key 3-2 is pressed, the processing device 5 moves to processing G and moves the reference point coordinates of the figure to be moved stored in the storage device 2 in the specified direction. The amount is corrected and the movement position mark 1-11 is displayed as an inverted filled rectangle (11 dots x 11 dots). At this time, since the cursor key 3-2 is used to specify the destination, the cursor 1-9 is deleted in consideration of operability. In addition, since the reference point mark 1-10 and the movement position mark 1-11 are displayed with reversed fill, they can be easily distinguished even if they interfere with other figures.After the movement position mark 1-11 passes on the figure line, Return to the original shape display. Also, cursor key 3
The -2 input supports the repeat function, so if you keep pressing it, it will be a continuous movement instruction. When the operator confirms by the movement position mark 1-11 that the figure to be moved is at the desired position by the movement operation, the operator presses the execution key 3-3. The processing device 5 determines this key input in process H, completes the movement operation, and moves on to the process.

In processing, the processing device 5 selects movement target figures 1-5, 1-6, 1- from the figure information in the storage device 2.
7, the graphic information of 1-8 is searched, and the coordinate position in the corresponding graphic information is corrected to the destination coordinate position. Next, moving to process J, as shown in FIG.
Delete the source shape that was displayed and display the new destination shape. In addition, matrix display 1
-2, the graphic function operation display is displayed, and the cursor 1-9 is displayed again within the graphic area frame, and the mode is set to wait for input of the next graphic editing function.

Although the above embodiment relates to a movement processing function, it can be similarly implemented to designate a target figure for functional operations such as copying, deletion, line type, line width, etc.

According to this embodiment, one graphic editing process can be operated in an interactive manner, and the graphic to be edited is displayed in reverse and recovered, so that operability is good.

2 Since the graphic area is framed, it is convenient to check the placement of figures during input, movement, and copying operations, and the balance between figures within the area.

3. Since the amount of movement of the cursor can be changed alternately in units of 1 dot and units of 7 dots, the cursor can be easily aligned with the desired figure even among mixed figures.

4. Providing a function key that targets all shapes including the cursor will further improve operability.

There are other effects.

〔Effect of the invention〕

According to the present invention, a figure editing control device using a monochrome screen display is adopted, since the target figure is displayed in reverse so that its outline becomes a double line to distinguish it from non-target figures. The target figure can be easily confirmed in the process, and the operability is improved.
