Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus capable of easily realizing an operating method for setting a line segment or a circular arc as a guideline for arranging a character string along it.

[0002]

2. Description of the Related Art Conventionally, in the field of typesetting and electronic publishing, evenly arranging a character string along a line segment is called "straight line combination", and arranging a character string along an arc is called "arc combination". In an information processing apparatus that performs document processing, a straight line combination and a circular arc combination are adopted for the editing process.

Specifically, a "character processing device" described in JP-A-63-139391 and JP-A-63-1083 are disclosed.
There is a technique of "character processing device" described in Japanese Patent Publication No. 92-92, and in these techniques, in order to set a guideline 20 which is a reference for arranging a character string, in the case of a straight line combination, FIG. As shown in (a), the starting point P of the line segment
s21 and the end point Pe22 are input, and in the case of a circular arc combination, as shown in FIG.
Generally, the operation procedure of inputting 21, the passing point Pj23 on the way, and the end point Pe22 of the circular arc.

[0004]

In the above technical technique, the user can set the intended guide line by inputting the start point and the end point in the case of the straight line combination. However, in the case of the arc combination,
In addition to the start point and the end point, the passing point must be input, which causes a problem as described below.

That is, for example, when it is desired to arrange a character string along a circle that has already been displayed in a document, it is necessary to set arcs having bulges at equal intervals as the circumference of the circle as a guideline. However, it is difficult to input the passing point of such an arc only by relying on the visual sense.

Further, since the guideline setting operation in the case of the straight line set and the guideline setting operation in the case of the arc set are different operation procedures, there is a problem that it is complicated.

As described above, the above-mentioned conventional technique has a problem in that the user cannot always set an arc having an intended bulge.

An object of the present invention is to solve these problems and to provide a guideline setting operation method of changing to a circular arc while adjusting the bulge of a line segment connecting two points. By doing so, it becomes possible to make common the setting operation of the guideline in the case of the straight line assembly and the setting operation of the guideline in the case of the arc construction, and the user can easily set the guideline. become.

[0009]

In order to achieve the above object, the present invention provides an information processing apparatus including a display device, an input device for receiving coordinate positions on a display screen of the display device, and a processing device. In the above, the input device receives a coordinate position indicating a start point and an end point and requests a large bulge of a line segment connecting the start point and the end point, and a small bulge. And a second segment that connects the start point and the end point when the input device receives the coordinate position indicating the start point and the end point. When the line segment display means for displaying on the display screen of the display device and the input device receive the first instruction, the bulge of the line segment connecting the start point and the end point is largely changed, and ,
When the input device receives the second instruction, it has arcuate display means for changing the bulge of the line segment connecting the start point and the end point to a smaller value.

In the case of such a configuration, the arc display means, in detail, (1) The input is made when the line segment display means is displaying a line segment on the display screen of the display device. When the device receives the first instruction, the line segment is changed to a circular arc having a predetermined minimum bulge,
(2) When the input device accepts the first instruction when an arc is displayed on the display screen of the display device,
When the bulge of the circular arc is largely changed by one predetermined step, and (3) the circular arc is displayed on the display screen of the display device, when the input device receives the second instruction, If the arc is the arc having the minimum bulge, the arc is changed to a line segment, and if the arc is not the arc having the minimum bulge, the bulge of the arc is determined by one predetermined step. You can make it smaller, and so on.

Further, according to the present invention, in an information processing apparatus including a display device, an input device for receiving a coordinate position on the display screen of the display device, and a processing device, the input device indicates a start point and an end point. While accepting the coordinate position,
A line segment connecting the start point and the end point is defined by 2
A first instruction requesting to be inflated in a first direction out of the two directions, and a line segment connecting the start point and the end point to a second direction out of two directions perpendicular to the line segment. A line that connects the start point and the end point when the processing device receives the coordinate position indicating the start point and the end point when the second instruction that requests to inflate in the direction is received. A line segment display means for displaying a minute on the display screen of the display device and a line segment connecting the start point and the end point when the input device receives the first instruction. And an arc display means for expanding the line segment connecting the start point and the end point in the second direction when the input device receives the second instruction. .

In the case of such a configuration, the arc display means is, in detail, (1) when the line segment display means displays a line segment on the display screen of the display device, the input is made. When the device receives the first instruction, the line segment is changed to a circular arc bulging in the first direction (hereinafter, referred to as a convex circular arc) having a predetermined minimum bulge,
(2) When the input device receives the first instruction when the convex arc is displayed on the display screen of the display device, the bulge of the convex arc is reduced by one predetermined step. (3) When the input device receives the second instruction when the convex arc is displayed on the display screen of the display device, the convex arc has the minimum bulge. If it is a circular arc, the convex circular arc is changed to a line segment, and if the convex circular arc is not the circular arc having the minimum bulge, the bulge of the convex circular arc is reduced by one predetermined step. (4) When the input device receives the second instruction when the line segment display means displays the line segment on the display screen of the display device, the line segment is predetermined. With a minimum bulge, the arc bulging in the second direction (hereinafter, (5) If a concave arc is displayed on the display screen of the display device and the input device receives the second instruction, the bulge of the concave arc is changed to (5). Is greatly changed by one predetermined step, and (6) when the input device receives the first instruction when the concave arc is displayed on the display screen of the display device, the concave If the circular arc is the circular arc having the minimum bulge, the concave circular arc is changed to a line segment, and if the concave arc is not the circular arc having the minimum bulge, the bulge of the concave circular arc is previously set. It is possible to make a small change by one fixed step.

In any of the configurations, the arc display means is on the perpendicular bisector of the line segment connecting the start point and the end point, and the distance to the start point and the end point. An arc connecting the start point and the end point of a circle whose center is a point whose distance between and is equal to the value of the predetermined variable is obtained, and the value of the predetermined variable is predetermined. By increasing or decreasing by the value, the bulge of the arc can be increased or decreased stepwise.

Further, the input device further accepts the designation of the character string, and the line segment display means displays the line segment displayed on the display screen of the display device, or the arc display means displays the display device of the display device. The placement instruction requesting to place the character string in the arc displayed on the display screen is received, and the processing device further, when the input device receives the placement instruction, the line segment display means is A line segment displayed on the display screen of the display device, or a character string accepted by the input device along the arc displayed on the display screen of the display device by the arc display means. It is possible to have a character string arranging means for arranging.

[0015]

According to the present invention, when the user inputs the coordinate positions indicating the start point and the end point from the input device, the line segment display means displays the line segment connecting the start point and the end point on the display device. Displayed on the screen. When the user inputs a first instruction requesting to increase the bulge of the line segment from the input device while the line segment connecting the start point and the end point is displayed on the display screen of the display device. The arc display means changes the line segment into an arc having a predetermined minimum bulge. Further, each time the user inputs the first instruction from the input device while the arc connecting the start point and the end point is displayed on the display screen of the display device, the arc display means displays The bulge of the arc increases by one step, which is predetermined.

Further, while the arc connecting the start point and the end point is displayed on the display screen of the display device, the user
Each time a second instruction for reducing the bulge of the circular arc is input from the input device, the circular arc is displayed by the circular arc display means until the bulge returns to a line segment again in a predetermined step. It gets smaller by the minute.

As described above, when setting a circular arc, the user only needs to input the start point and the end point, as in the case of setting the line segment, and does not need to input the passing point.

Further, the setting operation of the arc appears to the user to adjust the bulge of the line segment connecting the two points.

Therefore, when setting a line segment or an arc as a guideline for arranging a character string along it, the setting operation of the guideline in the case of a straight line combination, and
It becomes possible to standardize the setting operation of the guideline in the case of the set of arcs, and the user can easily set the guideline.

By reflecting in T5, the cursor is displayed on the display screen of CRT5. Further, the moving direction and the moving amount input by the user are read from the PD 8 and C is read correspondingly.
By changing the display position of the cursor on the display screen of RT5, the cursor moves on the display screen of CRT5 according to the operation of PD8.

Further, the CPU 1 performs various processes based on an instruction input by the user from the PD 8 or KB 6,
The data that is the processing result is written in the MM2 and the VRAM3. In the following description, the information processing apparatus of this embodiment is

By transferring the data to 10, the document data is registered in the floppy.

Next, a guideline setting operation procedure implemented in the above-described information processing apparatus will be described with reference to FIGS.

When the user wants to set a guideline in which a desired character string should be arranged, the user first inputs the start point Ps of the guideline from the PD 8. When the starting point Ps is input, a mark indicating the position of the starting point Ps is displayed on the display screen of the CRT 5, as shown in FIG. In FIG. 3, 30 is a cursor, and 21 is a mark indicating the position of the starting point Ps.

Then, the user inputs the end point Pe of the guideline from the PD 8. When the end point Pe is entered, C
On the display screen of RT5, as shown in FIG.
Is displayed, and a line segment connecting the starting point Ps and the ending point Pe is displayed as a guideline. In FIG. 4, 22 is a mark indicating the position of the end point Pe, and the mark 21 and the mark 22 are connected by a line segment 20.

Here, when the user wants to arrange a character string along a line segment connecting the starting point Ps and the end point Pe as a guideline (that is, in a straight line combination), for example, KB6 By pressing the execute key, an instruction to arrange the character string is input. When the execute key is pressed, a character string is arranged and displayed on the display screen of the CRT 5 along a line segment connecting the start point Ps and the end point Pe.

Note that the user can specify the character string to be arranged before or after the start point Ps and the end point Pe are input before or after the execution key is pressed.

Further, when the user wants to arrange a character string along the guideline (that is, in a combination of arcs) with the arc connecting the start point Ps and the end point Pe as a guideline, the user can set the start point Ps and the end point Pe. With the line segments connected to each other, the line segment is changed to a circular arc.

This operation depends on which of two directions the line segment is inflated to change into an arc.
There are kinds of operations. In the present embodiment, of the points that can be the center of the circular arc, the direction in which the Y coordinate is large, that is, the case where the circular arc is convex upward is referred to as a “convex circular arc” and an instruction to change to a convex circular arc is given. It is assumed that the plus key of KB6 is pressed. In addition, of the points that can be the center of the arc, the direction in which the Y coordinate is small, that is, the case where the arc is convex downward is referred to as a "concave arc" and an instruction to change to a concave arc is given.
It is assumed that the minus key of KB6 is pressed. However,
When the Y coordinates of the two center points are the same, the direction in which the X coordinate is large is called a convex arc, and the direction in which the X coordinate is small is called a concave arc. The definition of unevenness is not limited to this because it does not relate to the essence of the present invention.

When the user wants to change to a convex arc on the display screen of the CRT 5 shown in FIG. 4, he presses the plus key of KB6 to input an instruction to change to a convex arc. When the plus key is pressed, the start point Ps and the end point P are displayed on the display screen of the CRT 5 as shown in FIG.
The starting point Ps and the end point of a circle centered on the center point Po such that the distance between the starting point Ps and the end point Pe is a radius r, which is on a perpendicular bisector to the line segment connecting with e A convex arc connecting with Pe is displayed. When the plus key is pressed for the first time, the center point Po is determined so that the value of the radius r becomes rmax, which is the maximum value predetermined by the system.

In FIG. 5, 24 is the center point Po,
25 is the radius r (= rmax), and the start point Ps and the end point P
It is connected to e by a convex arc 20. Further, 27 is the minimum value that the value of the radius r can take, that is, the start point Ps and the end point P.
It shows rmin which is half the distance of the line segment connecting with e. That is, when the value of the radius r is rmin, it means that the center point Po is located on the line segment connecting the start point Ps and the end point Pe.

When the user presses the plus key once with the line segment connecting the start point Ps and the end point Pe, the line segment has the smallest curvature in the system. It is changed to a convex arc close to.

When the value of the radius r is not rmin,
There are two points that can be the center point Po, but in order to distinguish two arcs (convex arcs and concave arcs) centered on these two center points, in the present embodiment, the start point Ps and the end point Pe. A status, which is a variable for indicating the state of the guideline connecting between and, is introduced. When status = 1, the starting point Ps and the end point Pe are connected by a convex arc, and status = −1. If there is a starting point P
It is assumed that s and the end point Pe are connected by a concave arc. When the status = 0, the start point Ps and the end point Pe are connected by a line segment. The status is used in the processing of the information processing apparatus described later.

When the user continues to press the plus key, the value of the radius r decreases by a constant value α, and the curvature of the convex arc displayed is gradually increased accordingly. The display screen of the CRT 5 when the plus key is pressed twice is as shown in FIG.

Since the value of the radius r does not become smaller than rmin, when the value of the radius r decreases by a constant value α, and rmin> r (> 0), the radius r becomes smaller. The value is set to a negative value and the CRT
On the display screen of No. 5, as shown in FIG. 7, since it is a convex arc, the longer one of the arcs connecting the start point Ps and the end point Pe is displayed.

As described above, in this embodiment, the radius r takes either a positive value or a negative value, and when the radius r takes a positive value, the starting point Ps and the end point are The shorter arc of the two arcs connecting to Pe is displayed, and when a negative value is taken, the long arc of the two arcs connecting to the start point Ps and the end point Pe. By displaying the other circular arc, it is possible to gradually increase the curvature while maintaining a convex circular arc (or a concave circular arc). That is, even if the value of the radius r is negative, the absolute value of the radius r continues to increase. Therefore, the absolute value of the radius r is used as the value of the radius r used when displaying an arc. You can do it like this.

The value of the radius r is decreased by a constant value α until the value of the radius r reaches a minimum value -rmax which is predetermined by the system, and accordingly, the convex arc displayed is The curvature gradually increases.

On the other hand, when the user wants to change to a concave arc on the display screen of the CRT 5 shown in FIG.
By pressing the minus key of 6, an instruction to change to a concave arc is input. When the minus key is pressed,
On the display screen of the CRT 5, as shown in FIG.
A start point of a circle centered on a center point Po that is on a perpendicular bisector to a line segment connecting s and the end point Pe and has a radius r between the start point Ps and the end point Pe A concave arc connecting Ps and the end point Pe is displayed. When the minus key is pressed for the first time, the value of the radius r is rma, which is the maximum value predetermined by the system.
The center point Po is determined so as to be x.

In FIG. 8, 24 is the center point Po,
25 is the radius r (= rmax), and the start point Ps and the end point P
It is connected to e with a concave arc 20. Further, 27 is the minimum value that the value of the radius r can take, that is, the start point Ps and the end point P.
It shows rmin which is half the distance of the line segment connecting with e.

As described above, when the user presses the minus key once with the line segment connecting the start point Ps and the end point Pe, the line segment has the smallest curvature in the system.
It is changed to a concave arc close to a line segment.

Further, when the user continues to press the minus key, the value of the radius r decreases by a constant value α, and the curvature of the concave arc displayed is gradually increased accordingly. CRT when the minus key is pressed twice
The display screen of No. 5 is as shown in FIG.

Since the value of the radius r does not become smaller than rmin, when the value of the radius r decreases by a constant value α, and rmin> r (> 0), the radius r becomes smaller. The value is set to a negative value and the CRT
On the display screen of No. 5, as shown in FIG. 10, since it is a concave arc, the longer one of the arcs connecting the start point Ps and the end point Pe is displayed.

Then, the value of the radius r is decreased by a constant value α until the value of the radius r reaches the minimum value -rmax which is predetermined by the system, and accordingly, the concave arc displayed is changed. The curvature gradually increases.

By the way, if the user continues to press the minus key while the convex arc is displayed as a result of the user continuously pressing the plus key several times, the radius until the convex arc returns to the line segment. The value of r is incremented by a constant value α, and the curvature of the convex arc displayed is gradually reduced accordingly.

If the user continues to press the plus key while the concave arc is displayed as a result of the user continuously pressing the minus key several times, the radius until the concave arc returns to the line segment. The value of r is incremented by a constant value α, and the curvature of the concave arc displayed is gradually reduced accordingly.

FIG. 1 is a processing flowchart of the information processing apparatus according to the present embodiment in accordance with the guideline setting operation procedure.

The information processing apparatus first sets status = 0.
(Step 101) status = 0
Means that, as described above, the guideline connecting the start point Ps and the end point Pe is a line segment.

When the user inputs the starting point Ps from the PD 8 (step 102), a mark indicating the position of the starting point Ps is displayed on the display screen of the CRT 5 (step 103). The display screen of the CRT 5 at this time is the display screen shown in FIG.

Subsequently, when the user inputs the end point Pe from the PD 8 (step 104), a mark indicating the position of the end point Pe is displayed on the display screen of the CRT 5 (step 105). Then, since status = 0 here (step 106), a line segment connecting the start point Ps and the end point Pe is further displayed on the display screen of the CRT 5 (step 107). The display screen of the CRT 5 at this time is the display screen shown in FIG.

In this state, when the user presses the execution key of KB6 (step 108), since status = 0 (step 109), the display screen of the CRT 5 displays
A line segment connecting the start point Ps and the end point Pe is used as a guideline, and along the guideline (that is, in a straight line combination).
A character string is arranged and displayed (step 110).

When the user presses the plus key of KB6 with the line segment connecting the start point Ps and the end point Pe (step 108), since status = 0 (step 111), status = While setting to 1 (step 112), r = rmax is set (step 113).

Accordingly, thereafter, in step 106,
Since it is determined that status ≠ 0, C
On the display screen of RT5, it is on the perpendicular bisector to the line segment connecting the start point Ps and the end point Pe, and the start point Ps
And a convex arc connecting a start point Ps and an end point Pe of a circle centered on a center point Po such that the distance between the end point Pe and the end point Pe is a radius r (= rmax) (step 11).
4). The display screen of the CRT 5 at this time is the display screen shown in FIG.

Further, when the user continues to press the plus key (step 108), since the status is 1 (step 111), the value of the radius r is decreased by a constant value α (step 115), and in accordance therewith. , The curvature of a convex arc gradually increases. The display screen of the CRT 5 at this time is the display screen shown in FIG.

However, when the value of the radius r becomes rmin>r> 0 (step 116), r = -rmin is set (step 117), and the display screen of the CRT 5 displays
The longer one of the arcs connecting the start point Ps and the end point Pe is displayed. The display screen of the CRT 5 at this time is the display screen shown in FIG. 7.

If the radius r is smaller than -rmax (step 116), the radius r is kept at -rmax (step 118).

From this state, if the user continues to press the minus key (step 108), since status = 1 (step 119), a constant value α is added to the negative value of the radius r. By doing (Step 12
0), the absolute value of the radius r is decreased, and the curvature of the arc gradually decreases accordingly.

However, the value of the radius r is -rmin <r <0.
Is set (step 121), r = rmin is set (step 122), and on the display screen of the CRT 5,
The shorter one of the arcs connecting the start point Ps and the end point Pe is displayed.

Then, as a result of adding a constant value α to the value of the radius r, the value of the radius r (which is a positive value) is rma.
When it becomes larger than x (step 121), st
Atus = 0 is set, and the state where the start point Ps and the end point Pe are connected by a line segment is returned (step 123).

When the user presses the minus key of KB6 with the line segment connecting the start point Ps and the end point Pe (step 108), the status is 0 (step 119), and the status = -1 is set (step 114), and r = rmax is set (step 115).

Accordingly, thereafter, in step 106,
Since it is determined that status ≠ 0, C
On the display screen of RT5, it is on the perpendicular bisector to the line segment connecting the start point Ps and the end point Pe, and the start point Ps
And a concave arc connecting a start point Ps and an end point Pe of a circle centered on a center point Po such that the distance between the end point Pe and the end point Pe is a radius r (= rmax) (step 11).
4). The display screen of the CRT 5 at this time is the display screen shown in FIG.

Further, when the user continues to press the minus key (step 108), since the status is −1 (step 119), the value of the radius r is decreased by a constant value α (step 116). Accordingly, the curvature of the arc gradually increases. The display screen of the CRT 5 at this time is the display screen shown in FIG.

However, when the value of the radius r becomes rmin>r> 0 (step 117), r = -rmin is set (step 118), and the display screen of the CRT 5 displays
The longer one of the arcs connecting the start point Ps and the end point Pe is displayed. The display screen of the CRT 5 at this time is the display screen shown in FIG.

If the value of the radius r is smaller than -rmax (step 117), the value of the radius r is kept at -rmax (step 119).

From this state, if the user continues to press the plus key (step 108), the status is -1 (step 111). Therefore, a constant value α is added to the value of the radius r which is a negative value. By going (Step 11
0), the absolute value of the radius r is decreased, and the curvature of the arc gradually decreases accordingly.

However, the value of the radius r is -rmin <r <0.
Is set (step 131), r = rmin is set (step 132), and on the display screen of the CRT 5,
The shorter one of the arcs connecting the start point Ps and the end point Pe is displayed.

Then, as a result of adding a constant value α to the value of the radius r, the value of the radius r (which is a positive value) is rma.
When it becomes larger than x (step 131), st
Atus = 0 is set, and the state where the start point Ps and the end point Pe are connected by a line segment is returned (step 133).

Note that status = 1 or status
When the user presses the execution key of KB6 when s = −1 (steps 108 and 109), the arc displayed at that time is used as a guideline, and along the guideline (that is, in the arc combination). ) Arrange and display the character string (step 134).

Here, the process of arranging the character strings in the arc combination will be briefly described with reference to FIGS. 11 and 12.

As shown in FIG. 11, first, n points are obtained by dividing the arc by the number of characters n of the character string arranged along the arc (step 1101). However, as shown in Fig. 12, make sure that the letters on both ends to be placed are inside the arc.
Points 200-1 at both ends of points 200-1 to 200-n
1 and the point 200-n are respectively shifted inward by half the character width from both ends of the arc, and n-1 is equally divided between them.

Subsequently, for each character (step 1102, step 1105), the character pattern is rotated so that the character faces the center point Po of the arc at the corresponding point 200 (step 1103), and the corresponding point 2
A rotated character pattern is drawn around 00 (step 1104).

As described above, according to this embodiment,
By pressing the plus key and the minus key of KB6 from the state where the two points of the starting point Ps and the ending point Pe have been input, the user can easily change the uneven direction and the bulge of the arc connecting the starting point Ps and the ending point Pe. It has the advantage that it can be changed to.

Therefore, for example, as shown in FIG. 13, when it is desired to arrange a character string in an arc shape along a circle which is already displayed, an arc guide line having bulges at equal intervals with the circumference of the circle. It becomes possible to easily perform the setting operation. Further, as shown in FIG. 14, when the title area of the document is determined to some extent and it is desired to arrange the character strings in an arc shape so as to be accommodated therein, the degree of bulge of the arc is checked while checking the positional relationship with the document. Can be adjusted, and the operation of setting arc guide lines can be easily performed.

Further, according to the present embodiment, since the line segment connecting the two points of the start point Ps and the end point Pe is changed to a circular arc, the setting operation of the guideline in the case of straight line combination,
Also, the setting operation of the guideline in the case of the arc combination can be made common, and the setting operation of the guideline can be simplified. Further, the change between the line segment and the arc can be easily operated.

In the present embodiment, the plus key and the minus key are used to input the instructions for adjusting the concave-convex direction and the bulge of the arc, but the up cursor key and the down cursor key, the convex key and the Any key that has the opposite meaning, such as a concave key, may be used.

An operating method using the PD8 is also conceivable. In this case, as shown in FIG. 15, on the display screen of the CRT 5, there is a vertical bisector 28 with respect to the line segment connecting the starting point Ps21 and the end point Pe22, and between the starting point Ps and the end point Pe.
