As a result, the production load of a special graphic is reduced and the graphic editing efficiency is improved.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Technical Field The present invention is a graphic! The present invention relates to an i-collection device, and relates to a graphic editing device having a function of editing graphics in a word processor or the like.

Prior Art Conventionally, when editing figures using a word processor or personal computer, for example, when drawing a circle using a word processor, the center coordinates and radius were determined by taking into account the position and size of the circle to be drawn. , when drawing an equilateral triangle, calculate the coordinates of the three points by taking into account the position, size, and rotation (tilt) angle of the equilateral triangle to be drawn, and calculate the calculated coordinate values. This was done by inputting the

In addition, some shapes are preset in the shape editing function and can be selected, but in this case, the size of the shapes is limited and the selection range is narrow, and you can only select the shape you want. Even if you can specify the size, etc., you often have to make a selection based on how you feel when actually drawing it.

Therefore, when drawing a figure with special properties such as an equilateral triangle (having three sides of the same length), the operator must carefully consider the drawing position, the size of the figure, and the angle of rotation (tilt). It is necessary to take into account the following and calculate each coordinate accurately using theorems of the figure, which has the disadvantage of increasing mental burden, time-consuming work, and inefficient work.

Displaying the figure on the means, determining the size or rotation angle of the figure in accordance with an instruction to stop the changing operation inputted through the input means, and fixedly displaying the figure having the size or rotation angle at the time of inputting the instruction on the display means. It is characterized by Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

It consists of an input device such as a figure (30), into which data and instructions regarding figures are input.

The editing section 4 edits data related to graphics input from the input section 2 and graphic data stored in the storage section 6.

The display control section 8 reads the graphic data stored in the memory 8116, and displays the display section I n , t according to the instructions from the editing section 4.
-ffj control eggplant display unit lO is a display screen such as a CRT [Fig. 2 (22) 1
It displays data such as figures according to instructions from the display control section 8.

The figure changing system 12 is connected to the editing section 4, and the editing section 4
The coordinates of the figure are calculated according to the instructions, and the size or rotation angle of the figure is changed over time.

When creating a graphic using this device, the operator first uses the mouse 30 of the input unit 2 to specify the center point of the location where the graphic is to be displayed on the display screen 22 of the display unit 10.

Next, a figure to be drawn is selected using the function key 24 for specifying the type of figure, such as a circle, an equilateral triangle, or a square.

With the above input, the shape change system inside the device is activated,
The size and rotation (#I) angle of the specified figure change over time, and the state of change is displayed on the display screen 2 of the display unit 10.
2.

The operator looks at the changing state of the figures displayed on the display screen 22 and inputs an instruction using the "fixed key" 24b to stop the figure changing operation when one figure reaches the desired size and rotation angle. Enter from step 2. The operator can draw a desired figure by performing the above operations.

Next, an algorithm for drawing a circle will be explained with reference to flowcharts shown in FIGS. 4 and 5.

FIG. 4 shows an example of an algorithm for drawing a circle using this device.

First, the point specified by the mouse 30 is set as the center point of the figure to be drawn, and its coordinates are read (402).

Next, the initial setting value r of the radius to determine the size of the circle
Put lJ into the coefficient register i (404), and put the set unit change amount "10" into the radius register Δr (40B)
.

Next, in the process of change operation, the circle drawn by one radius is held for a certain period of time, or the operator presses the "fixed key" 2.
The set time "lOO" is entered into the timer register T that counts the display time until an instruction to stop the changing operation is given by step 4b (408).

Next, on the coordinates of the specified center point, display radius iΔr determined by the coefficient of coefficient register i and radius register Δr
Draw and display a circle (in this case lxΔrglo) (4
10).

Next, while displaying the circle in step 410, it is determined whether or not the operator inputs the "fixed key" 24b (412), and if the "fixed key" 24b is input, the operation is stopped. However, if there is no input, the process moves to the next step.

In step 412, if there is no input from the "fixed key" 24b, the set time "〒-1" is entered in the timer register T.
In other words, in this example, "98" is entered (414).

Next, it is necessary to judge whether the time register T is "0" or not.
), if the time register T is other than rOJ, the process returns to step 410, and if it is rOJ, the process moves to step 418.

In step 41B, when the clock register T reaches rOJ and reaches the set time of "100", the coefficient "country", that is, "2" is entered in the radius coefficient register i (418).
.

Next, the coefficient of coefficient register i is rl, which is the maximum coefficient set.
420), r100J
In the following cases, the process returns to step 408, and the coefficient of the coefficient register i and the radius register Δr are placed on the coordinates of the specified center point.
Display radius iΔr determined by (in this case 2!Δr=
20) Draw and display the circle (41G).

In step 420, if the coefficient of coefficient register i exceeds the set maximum coefficient rloOJ, that is, if the display radius iΔr becomes the maximum, the initial setting value "1" is put in coefficient register i (422), and step Return to 408.

According to this embodiment, when the operator specifies the center point of a circle using the mouse 30, the shape change system in the device is activated, and the shape changes from the preset minimum circle to the maximum circle at regular intervals, and the The status is displayed on the display screen 22 of the display unit 10.

Therefore, the operator can check whether the yen displayed on the display screen is 16 ÷ 1 ■ or not.

A desired circle can be drawn by inputting an instruction to stop the changing operation using the "fixed key" 24b of the input section 2.

Moreover, when the changing circle reaches the preset maximum circle, it returns to the minimum circle again and repeats the changing operation of increasing from the minimum circle, so in the first changing operation, first confirm the desired size of the circle, and then The size can be determined by the following change operation.

FIG. 5 shows another example of an algorithm for drawing a circle using this device.

"Circle key" to specify drawing of a circle from the operator [
Figure 2 (24B When the month is input, first set the initial radius value rlJ to determine the size of the circle in the coefficient register i.
(502), and the setting unit change amount "lO" is entered into the radius register Δr (5G4).

Next, when the operator uses the mouse 30 of the input unit 2 to specify the location on the display screen where he wants to display the circle, the point specified using the mouse 30 is set as the center point of the circle to be drawn, and its coordinates are read (50B ).

Next, it is determined whether or not the operator inputs the "fixed key" 24b instructing the determination of the size of the circle (508).
If there is an input, the operation ends; if there is no input, the process moves to step 510.

Step 5 (If there is no input using the "fixed key" 24b in Step 18, use the "enlarge key" that performs a circle changing operation only while the operator presses it) [Figure 2 (Determine whether there is an instruction by 240 However, if there is an instruction using the "enlargement key" 24c, the process moves to step 512, and if there is no instruction, the process returns to step 508.

In step 510, if there is an instruction using the "enlargement key" 24c, the coefficient "i◆1" is stored in the radius coefficient register i.
” In other words, enter “2” (512).

Next, the coefficient of coefficient register i is rl, which is the maximum coefficient set.
514), rlOQJ
In the following cases, the process moves to step 518, and the coefficient of the coefficient register i and the radius register Δr are placed on the coordinates of the specified center point.
The display radius iΔr determined by K (in this case, 2xΔra
Draw and display the circle 2Q) 518) and return to step 508.

In step 514, if the coefficient of coefficient register 1 exceeds the set maximum coefficient rlooJ, that is, if the display radius iΔr becomes the maximum, the initial setting value is "1".
into coefficient register i (51B), display radius iΔr
(In this case l!Δralo), draw a circle and display 5
18), return to step 508.

Therefore, while the operator presses the "enlarge key" 24c without making any input using the "fixed key" 24b, the circle changing motion is performed.

According to this embodiment, when the operator presses the "enlarge key" 24C after specifying the center point of the circle with the mouse 30, the figure change system in the device is activated, and while the "enlarge key" 24c is pressed, The preset minimum circle to maximum circle changes over time, and the state of the change is displayed on the display screen 22 of the display unit IO.

Therefore, the operator can watch the changing state of the circle displayed on the display screen 22 and when the circle reaches the desired size,
A desired circle can be drawn by canceling the operation of the "enlarge key" 24c and inputting an input using the "fixed key" 24b to instruct determination of the size of the circle.

Furthermore, when the changing circle reaches a preset maximum circle, it returns to the minimum circle again and repeats the changing operation, so it is possible to confirm the desired size of the circle and draw it.

FIG. 3 shows an example of an algorithm for drawing a circle using a conventional device.

First, a point specified by a mouse (corresponding to the mouse 30 in this embodiment) is set as the center point of a figure to be drawn, and its coordinates are read (32).

Next, determine whether there is a mouse click that specifies the radius of the circle.34) If there is a mouse click, use the coordinates of the center point of one figure and the mouse click. Find the distance of the coordinates and determine the radius of the 5 circles (3B).

Draw a circle using the radius determined by stay and block 3B and the center point of the specified shape (38).

A circle is drawn by entering the diameter. Therefore, the radius that determines the size of a diagram had to be determined by feeling and imagining a circle drawn on the display screen (corresponding to the display screen 22 of this embodiment).

Next, an algorithm for drawing a square will be explained with reference to the flowchart shown in FIG.

First, the point specified by the mouse 30 is set as the center point of the figure to be drawn, and its coordinates are read (802).

Next, enter the initial setting value "0" of the angle for determining the rotation angle jΔ0 (Fig. 7) with the center point of the square as the principal point into the angle coefficient register j (804), and set " 5 degrees" into the angle register Δ0 (soe).

Next, count the display time for displaying the square drawn by one rotation angle during the change operation process for a fixed period of time or until the operator instructs to stop the change operation using the "fixed key" 24b. + -';

Next, with the specified center point as the center, set the distance from the center point to each end point of the square as the minimum value "1o", and set the display rotation angle jΔθ (in this case 0x5=O) square,
In other words, draw and display the minimum square with a display rotation angle of 0 degrees (
810).

Next, while displaying the square in step 810, it is determined whether or not there is an input from the operator to stop the angle variation using the "fixed key" 24b (612), and if there is an input, the process moves to step 824, If there is no input, the process moves to the next step 614.

In step 612, if there is no input from the "fixed key" 24b, the set time rT-I is stored in the timer register T.
Enter J, or "89" (814).

Next, it is necessary to judge whether the time register T is rOJ or not.81B

Next, it is determined whether the coefficient of the angle coefficient register j exceeds the set maximum coefficient "71" (820), "71".
In the following cases, the process returns to step 808, and the distance from the center point to each end point is rlOJ, and the display rotation angle jΔ0 (
1!5=5), that is, in this case, the smallest square with a display rotation angle of 5 degrees is drawn and displayed (eto).

In step 820, if the coefficient of the degree angle coefficient register j exceeds the set maximum coefficient "71", that is, if the display rotation angle jΔθ has reached the maximum, the initial setting value rQJ is put into the angle coefficient register j ( G22),
Return to step 808.

Next, in step 812, if the operator instructs to stop the angle change operation using the "fixed key" 24b while the square is being displayed, the coefficient for determining the size of the square, that is, the specified Put the initial setting value "1" of the distance from the center point to each end point of the square into the coefficient register i (
ff24), the setting unit change amount "lO" is input into the register Δr (82B).

Next, in the changing motion process, a square drawn by one distance from the center point to each end point of the square is drawn for a certain period of time.
Alternatively, the set time rloooJ is entered into the timer register T that counts the display time until the operator instructs the user to stop the changing operation using the "fixed key" 24b (G28).

Next, on the coordinates of the designated center point at the display rotation angle jΔθ in step 812, the display distance iΔr (in this case l!Δr=1
Draw and display a square as shown in Figure 7 of 0) (83

Next, while displaying the square in step 630, it is determined whether or not there is an instruction from the operator to cancel the changing operation using the "fixed key" 24b (832), and the "fixed key 2"
If there is an input from 4b, the operation is stopped at 1hL, and if there is no input, the process moves to the next step.

In step 632, if there is no input using the "fixed key" 24b, the set time rT-
Enter ``99'' (634).

Next, it is necessary to judge whether the time register T is rOJ or not.83G
), if the time register T is other than roJ, the process returns to step 830, and if it is rOJ, the process moves to step 638.

In step 83B, when the time register T becomes "0" and the set time rlOQJ is reached, a coefficient ri+lJ, or "2", is entered in the distance coefficient register i indicating the size (838).

Next, the coefficient of coefficient register i is rl, which is the maximum coefficient set.
840), rloOJ
In the following cases, the process returns to step 628 and step 612
At the display rotation angle jΔ0, the display distance iΔr is determined by the coefficient register i, which is the coefficient of the distance from the center point to each end point of the square, and the distance register Δr (in this case, 2!Δr=
20) and displays the square (830).

In step 840, if the coefficient in coefficient register i exceeds the set maximum coefficient rloOJ.

In other words, when the display radius iΔr becomes the maximum, the initial setting value rlJ is put into the coefficient register i (842), and the stay

A desired square can be drawn by inputting with the "fixed key" 24b of 2.

Moreover, the changing square repeats the change operation when the preset rotation angle reaches the maximum rotation angle, returns to the minimum rotation angle, and returns to the minimum rotation angle again when the size reaches the maximum, so check the desired square size. You can draw the diagram using Further, in the above embodiments, an example of a graphic change from a minimum to a maximum is shown in terms of size or rotation angle, but it can also be applied to a case where a reduction change from a maximum to a minimum is performed.
