Abstract

PURPOSE:To correct a figure easily by storing the information to draw the figure as a point string and, when a shift key reaches a changing position in the point string, inputting a correction command. CONSTITUTION:When a figure to be drawn is specified and keyed in by a figure specification key 2, the shape information is stored in a storage part 6. When a broken line is to be drawn as an example, the starting point and the end terminal of each straight line segment of the broken line are successively specified on a tablet board 1, so that the coordinate position information of the point string is stored in the storage part 6 through a storage controlling part 7 and displayed on a display device 8. If the position of the 2nd point is to be corrected, a pointer indicating a storage area in the storage part 6 is returned to the status of the position of two points before the present position by the controlling part 7 when the shift key 4 is depressed twice. Consequently the carsor of the device 8 is shifted to the position of P2. When a correction command key 3 is depressed and a point Q is specified on the board 1, the contents of the storage part 6 is rewritten to the coordinate position information of Q in accordance with the pointer indicated by the controlling part 7.

Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a device for creating and modifying graphics.

[4f# Background of the Invention] To create a figure, store it as a figure command and point sequence information, convert #I in the memory into a figure 4), and display it on a CRT display, etc. A method of displaying on a display device is adopted. The figure command here specifies the shape of the figure to be drawn hb, and the point sequence information specifies the orientation p and size of the figure to be drawn11.
For example, for a circle, the center point and one point on the circumference, for a line segment, the start and end points, and for a rectangle, two diagonal points are the point sequence i'#
Good news.

However, when modifying a figure created by the above method, conventionally there was only a temporary method of 11 & erasing the drawn figure and redrawing a new *KIIji in that position. In other words, even when making relatively small-scale or partial corrections, the user has to go through the procedures of deleting and creating a new one for each figure, and furthermore, the user has to carry out the procedure of deleting and creating a new one for each figure, and furthermore, the user has to carry out the procedure of deleting and creating a new one for each figure. I was unable to do anything.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a modification mechanism that solves the above-mentioned problems and can easily modify five figures.

[Structure of the invention]

For this purpose, an input means in the form of a moving key was provided. The essence of correction is correction of point sequence information, and this point sequence information is stored in a storage unit in an orderly manner, and furthermore, it is visualized into A chunks by one display device. The movement key is the ninth means by which the user freely accesses the past point sequence information (for one graphic creation period) that exists in the storage unit. By operating the movement keys, change the 1-point sequence.If you reach the 1st place and it is 9, manually execute the Modify iE command to change the 1-point sequence.As a result, the display on the display device will change according to the changed 9-point sequence. change. In other words, a correction has been made.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an outline of the embodiment of the apparatus. First, ・1
When the shape designation key 2 is used to designate the shape of the figure to be drawn (-juice, circle, square, etc.) and the key is pressed, information on that shape is sent to the memory s6 and stored. Now, as an example, if we consider four points to draw a polygonal line, we can sequentially specify the position where the polygonal line should be placed on the tablet surface l as the starting point and end point of the line segment. The position information of the seat Ili is sent to the memory s6 via the memory control unit 7 and stored there. Furthermore, these stored pieces of information are transformed into a visible graphic image and displayed on the display device 8.

If you want to correct the position of the second point now that you have drawn three one-minute lines that make up one line as shown in Figure 1, that is, you have specified four points on the tablet surface 1.1:. think of. At this time, by pressing the movement key 4 twice, the pointer 71 pointing to the storage area of the memory s6 as shown in FIG.
The storage unit d867 returns to the previous state 11. Further, in accordance with this, the cursor on the display device 8 moves to the position two positions earlier, that is, sP2. Here, by pressing "Correct" on the correction command key 3 and specifying a new point Q to replace P2 on the tablet surface L, the coordinate position information of this new nine point Q is stored in the memory system #. The data is stored in the storage section IJ7 of the storage section according to the pointer 71 pointed to by the pointer 71. That is, as shown in Figure 1M2, the contents of the area in which the coordinate position information of P2 was stored are rewritten to %Q(2) coordinate position information.

This result display A 8 is modified according to the contents of the storage section 6 and displays 9 folds 4 PI -Q-P3-P4. When the correction is completed, use movement key 5 to move the pointer of the storage control unit and the cursor of the display device back to the original position 111.
1 (P4) K: You can go back and continue creating folds.

The above example uses dI Tadashi as an example, but it is clear that it is also possible to delete and modify the closet monument in the same way. That is, as shown in FIGS. 3 and 4, it is sufficient to move the storage area of the dot sequence located at )'' of the storage area pointed to by the pointer up or down.

[The young fruits of invention]

In this way, by memorizing the information for drawing a figure as a sequence of points, it becomes possible to freely modify the figure using simple manual means such as moving keys.

That is, according to the present invention, it is possible to easily enlarge, reduce, change the position, etc. of a figure by returning to an arbitrary key point during figure creation and changing it, and then continue to create the figure. For example, when modifying a 2 circle, by changing one key point on the circumference, you can change half of the circle, and by changing the key point at the center point, you can change the shape of the circle. You can shift the center.

Also, since the change in the conflict is done by pointing the tapered board E, it can be considered to be more similar to Iruma's feeling.

[Modified example of the invention] In this embodiment, one key point returns by one each time the movement key is pressed 11Jj, but originally, the movement key was
Since this is a means for accessing past point sequence information, it is not limited to the configuration of this embodiment.

For example, it is possible to combine a numeric keypad and a movement key so that it jumps when you return to the previous key point specified by the numeric keypad, or you can move to past keypoints in proportion to the time you hold down the movement key. It is also possible to consider the structure of going back and forth.

First, in order to inform the user of the movement of the key point, this embodiment has a configuration in which a kernel is displayed on the display device, but the structure of this embodiment is such that the key point is inverted in black and white, displayed in color 4, etc. It's not something you can do.

Although the tablet board and the pointing pen are used as the position input device, any device that can input relative or absolute position information such as a tracking ball, stick, mouse, light pen, etc. may be used.
